Galveston Hurricane 1900
This killer weather system was first detected over the tropical Atlantic on August 27. While the history of the track and intensity is not fully known, the system reached Cuba as a tropical storm on September 3 and moved into the southeastern Gulf of Mexico on the 5th. A general west-northwestward motion occurred over the Gulf accompanied by rapid intensification. By the time the storm reached the Texas coast south of Galveston late on September 8, it was a Category 4 hurricane. After landfall, the cyclone turned northward through the Great Plains. It became extratropical and turned east-northeastward on September 11, passing across the Great Lakes, New England, and southeastern Canada. It was last spotted over the north Atlantic on September 15.

This hurricane was the deadliest weather disaster in United States history. Storm tides of 8 to 15 ft inundated the whole of Galveston Island, as well as other portions of the nearby Texas coast. These tides were largely responsible for the 8,000 deaths (estimates range from 6,000 to 12,000) attributed to the storm. The damage to property was estimated at $30 million...

Atlantic-Gulf Hurricane 1919
This fearsome cyclone was first detected near the Lesser Antilles on September 2. It moved generally west-northwestward for several days, passing near the Dominican Republic on September 4 and into the southeastern Bahamas on the 5th and 6th. At that time it became a hurricane. A westward turn on September 7 took the center across the central Bahamas on the 7th and 8th and into the Straits of Florida on the 9th. The now large hurricane was of Category 4 intensity as the eye passed just south of Key West, Florida and the Dry Tortugas on September 10. A continued west to west-northwestward motion brought the center to the Texas coast south of Corpus Christi as a Category 3 hurricane on September 14. The cyclone dissipated over northern Mexico and southern Texas the next day.

Although hurricane-force winds occurred over the Florida Keys and the central and south Texas coast, no reliable wind measurements are available from near the center. A storm surge of up to 12 ft inundated Corpus Christ, Texas causing major damage to the coastal areas. A ship moored near the Dry Tortugas measured a pressure of 27.37 inches as the center passed, and based on this, the storm is ranked as the third most intense to hit the United States.

The death toll was estimated at 600 to 900 people. Of these, more than 500 were lost on ten ships that either sunk or were reported missing. Damage in the United States was estimated at $22 million.

Great Miami Hurricane 1926
The "Great Miami" Hurricane was first spotted as a tropical wave located 1,000 miles east of the Lesser Antilles on September 11th. The system moved quickly westward and intensified to hurricane strength as it moved to the north of Puerto Rico on the 15th. Winds were reported to be nearly 150 mph as the hurricane passed over the Turks Islands on the 16th and through the Bahamas on the 17th. Little in the way of meteorological information on the approaching hurricane was available to the Weather Bureau in Miami. As a result, hurricane warnings were not issued until midnight on September 18th, which gave the booming population of South Florida little notice of the impending disaster.

The Category 4 hurricane's eye moved directly over Miami Beach and downtown Miami during the morning hours of the 18th. This cyclone produced the highest sustained winds ever recorded in the United States at the time, and the barometric pressure fell to 27.61 inches as the eye passed over Miami. A storm surge of nearly 15 feet was reported in Coconut Grove. Many casualties resulted as people ventured outdoors during the half-hour lull in the storm as the eye passed overhead. Most residents, having not experienced a hurricane, believed that the storm had passed during the lull. They were suddenly trapped and exposed to the eastern half of the hurricane shortly thereafter. Every building in the downtown district of Miami was damaged or destroyed. The town of Moore Haven on the south side of Lake Okeechobee was completely flooded by lake surge from the hurricane. Hundreds of people in Moore Haven alone were killed by this surge, which left behind floodwaters in the town for weeks afterward.

The hurricane continued northwestward across the Gulf of Mexico and approached Pensacola on September 20th. The storm nearly stalled to the south of Pensacola later that day and buffeted the central Gulf Coast with 24 hours of heavy rainfall, hurricane force winds, and storm surge. The hurricane weakened as it moved inland over Louisiana later on the 21st. Nearly every pier, warehouse, and vessel on Pensacola Bay was destroyed.
The great hurricane of 1926 ended the economic boom in South Florida and would be a $90 billion disaster had it occurred in recent times. With a highly transient population across southeastern Florida during the 1920s, the death toll is uncertain since more than 800 people were missing in the aftermath of the cyclone. A Red Cross report lists 373 deaths and 6,381 injuries as a result of the hurricane.

Hurricane Audrey 1957
Audrey was first detected over the southwestern Gulf of Mexico on June 24. It moved slowly northward as it became a tropical storm and a hurricane the next day. A faster northward motion brought the center to the coast near the Texas-Louisiana border on the 27th. Rapid strengthening in the last six hours before landfall meant Audrey made landfall as a Category 4 hurricane. The cyclone turned northeastward after landfall, becoming extratropical over northern Mississippi on June 28 and merging with another low over the Great Lakes the next day. The combined system was responsible for strong winds and heavy rains over portions of the eastern United States and Canada.

No reliable wind or pressure measurements are available from Audrey's core at landfall. The main impact was from 8 to 12 ft storm surges that penetrated as far inland as 25 miles over portions of low-lying southwestern Louisiana. These surges were responsible for the vast majority of the 390 deaths from Audrey. Damage in the United States was estimated at $150 million.

Hurricane Camille 1969
This powerful, deadly, and destructive hurricane formed just west of the Cayman Islands on August 14. It rapidly intensified and by the time it reached western Cuba the next day it was a Category 3 hurricane. Camille tracked north-northwestward across the Gulf of Mexico and became a Category 5 hurricane on August 16. The hurricane maintained this intensity until it made landfall along the Mississippi coast late on the 17th. Camille weakened to a tropical depression as it crossed Mississippi into western Tennessee and Kentucky, then it turned eastward across West Virginia and Virginia. The cyclone moved into the Atlantic on August 20 and regained tropical storm strength before becoming extratropical on the 22nd.

A minimum pressure of 26.84 inches was reported in Bay St. Louis, Mississippi, which makes Camille the second most intense hurricane of record to hit the United States. The actual maximum sustained winds will never be known, as the hurricane destroyed all the wind-recording instruments in the landfall area. The estimates at the coast are near 200 mph. Columbia, Mississippi, located 75 miles inland, reported 120 mph sustained winds. A storm tide of 24.6 ft occurred at Pass Christian, Mississippi. The heaviest rains along the Gulf Coast were about 10 inches. However, as Camille passed over the Virginias, it produced a burst of 12 to 20 inch rains with local totals of up to 31 inches. Most of this rain occurred in 3 to 5 hours and caused catastrophic flash flooding.

The combination of winds, surges, and rainfalls caused 256 deaths (143 on the Gulf Coast and 113 in the Virginia floods) and $1.421 billion in damage. Three deaths were reported in Cuba.

Hurricane Agnes 1972
The large disturbance that became Agnes was first detected over the Yucatan Peninsula of Mexico on June 14. The system drifted eastward and became a tropical depression later that day and a tropical storm over the northwestern Caribbean on the 16th. Agnes turned northward on June 17 and became a hurricane over the southeastern Gulf of Mexico the next day. A continued northward motion brought Agnes to the Florida Panhandle coast on June 19 as a Category 1 hurricane. Agnes turned northeastward after landfall and weakened to a depression over Georgia. However, it regained tropical storm strength over eastern North Carolina on June 21 and moved into the Atlantic later that day. A northwestward turn followed, and a just-under-hurricane-strength Agnes made a final landfall on the 22nd near New York, New York. The storm merged with a non-tropical low on June 23rd, with the combined system affecting the northeastern United States until the 25th.

Agnes was barely a hurricane at landfall in Florida, and the effects of winds and storm surges were relatively minor. The major impact was over the northeastern United States, where Agnes combined with the non-tropical low to produce widespread rains of 6 to 12 inches with local amounts of 14 to 19 inches. These rains produced widespread severe flooding from Virginia northward to New York, with other flooding occurring over the western portions of the Carolinas.

Agnes caused 122 deaths in the United States. Nine of these were in Florida (mainly from severe thunderstorms) while the remainder were associated with the flooding. The storm was responsible for $2.1 billion in damage in the United States, the vast majority of which came from the flooding. Agnes also affected western Cuba, where seven additional deaths occurred.

Tropical Storm Claudette 1979
Claudette was first detected as a tropical wave that moved off the African coast on July 11. The wave spawned a tropical depression on July 16 that briefly became a tropical storm the next day as it approached the Leeward and Virgin Islands. Claudette weakened to a tropical depression and then a tropical wave while passing near Puerto Rico on the 18th, and little re-development occurred until the system moved into the southeastern Gulf of Mexico on the 21st. Claudette regained tropical storm strength over the western Gulf on July 23 and made landfall the next day near the Louisiana-Texas border. It made a slow loop over southeastern Texas on the 24th and 25th, followed by a northward motion into Oklahoma on the 27th. The remnants of Claudette turned eastward and merged with a frontal system over West Virginia on July 29.

Claudette produced tropical storm conditions along portions of the Texas and Louisiana coasts, but the storm will be most remembered for its rainfall. Widespread amounts in excess of 10 inches occurred over portions of southeastern Texas and southwestern Louisiana, with several local amounts in excess of 30 inches. An observer west of Alvin, Texas reported 43 inches in 24 hours, which is a United States record for 24 hour rainfall amount. The storm total at that location was 45 inches. The rains produced severe flooding that was responsible for one death and $400 million in damage. The storm also produced heavy rains over portions of Puerto Rico that were responsible for one death.

Hurricane Alicia 1983
Alicia formed over the north central Gulf of Mexico on August 15. It drifted slowly westward and northwestward while steadily strengthening on the 16th and 17th. This motion brought Alicia over the western end of Galveston Island, Texas as a Category 3 hurricane on August 18. Alicia moved northwestward into Oklahoma as a tropical depression on August 19, then turned northward before dissipating over Nebraska on the 21st.

The Coast Guard cutter Buttonwood moored at Galveston reported sustained winds of 96 mph with gusts to 125 mph. Hobby Airport at Houston, Texas reported 94 mph sustained winds with gusts to 107 mph. Wind gusts of hurricane force in downtown Houston littered the streets with broken glass as windows broke in the high-rise buildings. Additionally, twenty-three tornadoes were reported from Alicia.

Hurricane Gilbert 1988
A tropical wave exiting the African coastline on September 3rd developed into the 12th tropical depression of the season on September 8th while approaching the Windward Islands. The cyclone rapidly strengthened to hurricane status on September 10th as a west-northwest motion brought Gilbert into the eastern Caribbean Sea. Gilbert passed directly over Jamaica on September 12th as a major hurricane, becoming the first direct impact for the island from a hurricane since 1951. Winds gusted to nearly 150 mph as Gilbert produced a 9-foot storm surge along Jamaica’s northeast coast. Jamaica was devastated as the eyewall traversed the entire length of the island. During this period the eye contracted from 25 nmi to only 12 nmi upon exiting Jamaica.

Gilbert emerged off the western coastline of Jamaica and began a period of extraordinarily rapid intensification. The ferocious hurricane strengthened to Category 4 status as its northern eyewall pounded Grand Cayman Island with 155 mph wind gusts early on September 13th. Gilbert’s remarkable intensification trend continued as the cyclone reached Category 5 status on the afternoon of the 13th and eventually reached peak winds of 185 mph. The minimum central pressure of the cyclone plummeted to 888 millibars, which represented a 70-millibar drop in only a 24-hour period. This minimum central pressure recorded by NOAA aircraft remains the lowest pressure ever recorded in the western hemisphere. Gilbert crossed the northeast coast of Mexico’s Yucatan peninsula on September 14th, becoming the first Category 5 hurricane in the Atlantic basin to strike land since Camille in 1969.

Gilbert weakened over the Yucatan peninsula and emerged into the western Gulf of Mexico as a Category 2 hurricane. Gilbert’s large circulation regained major hurricane status as the cyclone continued on a west-northwest course on the 16th. The hurricane made its final landfall near the town of La Pesca on the Mexican Gulf Coast on the evening of September 16th as a strong Category 3 hurricane. Gilbert’s remnants spawned 29 tornadoes over Texas on September 18th, with flooding spreading to the Midwest as the remnants merged with a frontal boundary over Missouri on September 19th. Although no reliable measurements of storm surge exist from Gilbert’s two Mexican landfalls, estimates are that Gilbert produced between 15 and 20 feet of surge along the Yucatan and 8 to 13 feet at landfall in mainland Mexico.

Gilbert’s large size and impacts were felt over much of the Caribbean, Central America as well as portions of the United States. The death toll of 318 gives an idea of the scope of Gilbert's impacts: Mexico 202, Jamaica 45, Haiti 30, Guatemala 12, Honduras 12, Dominican Republic 5, Venezuela 5, United States 3, Costa Rica 2, and Nicaragua 2. The deaths from Costa Rica, Guatemala, Honduras, Nicaragua, and Venezuela were caused by inland flash flooding from outer rainbands.

Hurricane Andrew 1992
 The most destructive United States hurricane of record started modestly as a tropical wave that emerged from the west coast of Africa on August 14. The wave spawned a tropical depression on August 16, which became Tropical Storm Andrew the next day. Further development was slow, as the west-northwestward moving Andrew encountered an unfavorable upper-level trough. Indeed, the storm almost dissipated on August 20 due to vertical wind shear. By August 21, Andrew was midway between Bermuda and Puerto Rico and turning westward into a more favorable environment. Rapid strengthening occurred, with Andrew reaching hurricane strength on the 22nd and Category 4 status on the 23rd. After briefly weakening over the Bahamas, Andrew regained Category 4 status as it blasted its way across south Florida on August 24. The hurricane continued westward into the Gulf of Mexico where it gradually turned northward. This motion brought Andrew to the central Louisiana coast on August 26 as a Category 3 hurricane. Andrew then turned northeastward, eventually merging with a frontal system over the Mid-Atlantic states on August 28.

Reports from private barometers helped establish that Andrew's central pressure at landfall in Homestead, Florida was 27.23 inches, which makes it the third most intense hurricane of record to hit the United States. Andrew's peak winds in south Florida were not directly measured due to destruction of the measuring instruments. An automated station at Fowey Rocks reported 142 mph sustained winds with gusts to 169 mph (measured 144 ft above the ground), and higher values may have occurred after the station was damaged and stopped reporting. The National Hurricane Center had a peak gust of 164 mph (measured 130 ft above the ground), while a 177 mph gust was measured at a private home. Additionally, Berwick, LA reported 96 mph sustained winds with gusts to 120 mph.

Andrew produced a 17 ft storm surge near the landfall point in Florida, while storm tides of at least 8 ft inundated portions of the Louisiana coast. Andrew also produced a killer tornado in southeastern Louisiana.

Andrew is responsible for 23 deaths in the United States and three more in the Bahamas. The hurricane caused $26.5 billion in damage in the United States, of which $1 billion occurred in Louisiana and the rest in south Florida. The vast majority of the damage in Florida was due to the winds. Damage in the Bahamas was estimated at $250 million.

Tropical Storm Alberto 1994
Alberto was first detected as a tropical wave that moved off the African coast on 18 June. The wave moved into the western Caribbean by late June and formed into a tropical depression near the western tip of Cuba on June 30. The cyclone moved northwest through July 1 as it became a tropical storm, then it turned northward. This motion continued until the cyclone made landfall in the western Florida Panhandle on the 4th. Alberto then moved north-northeastward into western Georgia, where it did a loop on the 5th and 6th. The cyclone finally dissipated over central Alabama on July 7.

Alberto's winds and tides produced only minor damage at the coast, but the excessive rains that fell in Georgia, Alabama, and western Florida were another story. Amounts exceeded 10 inches in many locations, with the maximum being the 27.61 inch storm total at Americus, GA (including 21 inches in 24 hours). Severe flooding resulted over large portions of southern Georgia, western Alabama, and the western Florida Panhandle. The floods were responsible for 30 deaths and $500 million in damage.

Hurricane Opal 1995
Opal was first detected as a tropical wave moving off the African coast on September 11. The waved moved westward through the Atlantic and Caribbean and merged with a broad low pressure area over the western Caribbean on September 23. The combined system then developed into a tropical depression near the east coast of the Yucatan Peninsula on September 27. The depression drifted slowly northward, becoming Tropical Storm Opal as it reached the north coast of Yucatan on the 30th. Opal then moved slowly westward into the Bay of Campeche, where it became a hurricane on October 2. A gradual north-northeastward turn started later on the 2nd, with acceleration on the 3rd and 4th. Opal continued to strengthen, and a period of rapid strengthening late of the 3rd and early on the 4th made it a Category 4 hurricane. Weakening followed, and Opal was a Category 3 hurricane when it made landfall near Pensacola Beach, Florida late on the 4th. Opal continued quickly north-northeastward and became extratropical over the Ohio Valley on the 5th. The cyclone was last seen over the eastern Great Lakes on October 6.

Hurlbert Field, Florida reported sustained winds of 84 mph with a peak gust of 144 mph, and gusts to 70 mph occurred as far inland as northwest Georgia. However, the main impact from Opal was from storm surge. A combination of storm surge and breaking waves inundated portions of the western Florida Panhandle coast to a depth of 10 to 20 ft. The surge was responsible for the bulk of the $3 billion in damage attributed to Opal in the United States.

Opal was responsible for 9 deaths in the United States, including 8 from falling trees and one from a tornado. Opal was responsible for 50 deaths in Mexico and Guatemala due to flooding caused by heavy rains.

Tropical Storm Allison 2001
Allison's long and complex career began on 5 June as an area of disturbed weather over the northwestern Gulf of Mexico developed into a tropical storm. The storm made landfall near Freeport, Texas later that day. Allison weakened to a depression on the 6th, while drifting northward, then it made a slow loop over southeastern Texas from the 7th to the 9th. The cyclone moved into the Gulf of Mexico on the 10th and acquired subtropical characteristics. It then moved east-northeastward over southeastern Louisiana on the 11th, where it re-intensified into a subtropical storm. Allison weakened back to a subtropical depression on the 12th while continuing east-northeastward, and this motion carried it to southeastern North Carolina by the 14th where it again stalled. The cyclone drifted northward to northeastward drift over land on the 15th and 16th. This was followed by a faster northeastward motion on the 17th as the center emerged into the Atlantic. Allison regained subtropical storm strength later that day before becoming extratropical on the 18th southeast of Cape Cod. The system dissipated southeast of Nova Scotia the next day.

Allison brought tropical-storm-force winds and above normal tides to portions of the Texas and Louisiana coasts. However, the greatest legacy of the cyclone was the widespread heavy rains and resulting floods along the entire path of the cyclone (figure). Houston, Texas, was the worst affected area, as the Port of Houston reported 36.99 inches and several other locations reported more than 30 inches (figure). The storm also spawned 23 tornadoes. Allison was responsible for 41 deaths and at least $5 billion in damage in the United States, making it the deadliest and costliest U. S. tropical storm of record.

Hurricane Ivan 2004
Ivan developed from a large tropical wave that crossed the west coast of Africa on August 31, and spawned a tropical depression two days later. The depression reached storm strength on September 3rd (one of only a dozen on record to do so south of 10EN) and continued to strengthen. By the 5th , Ivan had become a hurricane about 1150 miles east of the southern Windward Islands. Eighteen hours later Ivan became the southernmost storm to reach major hurricane status, at 10.2EN. Ivan was a category 3 hurricane when the center passed about 7 miles south of Grenada, a path that took the northern eyewall of Ivan directly over the island. In the Caribbean, Ivan became a category 5 hurricane, with winds of 160 m.p.h., on the 9th when it was south of the Dominican Republic, and on two occasions the minimum pressure fell to 910 mb. The center of Ivan passed within about 20 miles of Jamaica on the 11th and a similar distance from Grand Cayman on the 12th , with Grand Cayman likely experiencing sustained winds of category 4 strength. Ivan then turned to the northwest and passed through the Yucatan channel on the 14th , bringing hurricane conditions to extreme western Cuba. Ivan moved across the east-central Gulf of Mexico, making landfall as a major hurricane with sustained winds of near 120 m.p.h. on the 16th just west of Gulf Shores, Alabama.

Ivan weakened as it moved inland, producing over 100 tornadoes and heavy rains across much of the southeastern United States, before merging with a frontal system over the Delmarva Peninsula on the 18th. While this would normally be the end of the story, the extratropical remnant low of Ivan split off from the frontal system and drifted southward in the western Atlantic for several days, crossed southern Florida, and re-entered the Gulf of Mexico on the 21st. The low re-acquired tropical characteristics, becoming a tropical storm for the second time on the 22nd in the central Gulf. Ivan weakened before it made its final landfall in southwestern Louisiana as a tropical depression on the 24th.

Ivan's storm surge completely over-washed the island of Grand Cayman, where an estimated 95% of the buildings were damaged or destroyed. Surge heights of 10-15 feet occurred along the Gulf coast during Ivan's first U.S. landfall. Peak rainfall amounts in the Caribbean and United States were generally 10-15 inches. The death toll from Ivan stands at 92 - 39 in Grenada, 25 in the United States, 17 in Jamaica, 4 in Dominican Republic, 3 in Venezuela, 2 in the Cayman Islands, and 1 each in Tobago and Barbados. U.S. damage is estimated to be near $14.2 billion, the third largest total on record.

Hurricane Dennis 2005
Dennis formed from a tropical wave that moved westward across the coast of Africa on June 29. A tropical depression developed from the wave on July 4 near the southern Windward Islands. The cyclone moved west-northwestward across the eastern and central Caribbean sea, became a tropical storm on July 5, and strengthened into a hurricane early on July 6 about 245 miles east-southeast of Jamaica. Dennis intensified over the next two days, becoming a major hurricane on July 7 and a Category 4 hurricane with winds of 150 mph the next day just south of central Cuba. Dennis passed over Cabo Cruz, Cuba early on July 8 with winds of 135 mph, and then made landfall along the south-central coast of Cuba that afternoon near Cienfuegos with winds of 145 mph. After landfall, Dennis passed near Havana and weakened to a Category 1 hurricane before emerging over the southeastern Gulf of Mexico early on July 9. Although Dennis re-intensified into a Category 4 hurricane with winds of 145 mph early on July 10 over the eastern Gulf of Mexico, it weakened to Category 3 strength before making landfall over the western Florida Panhandle near Navarre Beach late that day. Dennis degenerated to a low pressure area over the Tennessee and Ohio Valleys, and it was eventually absorbed by an extratropical low over southeastern Canada on July 18.

Dennis brought hurricane conditions to many portions of Cuba. Cabo Cruz reported sustained winds of 133 mph with a gust to 148 mph at 0200 UTC July 8, with a minimum pressure of 956 mb at 0240 UTC just before the eye passed over the station. The anemometer was destroyed, and it is possible more extreme winds occurred. Dennis also caused hurricane conditions in the western Florida Panhandle. An instrumented tower run by the Florida Coastal Monitoring Program (FCMP) at Navarre measured 1-min average winds (5-m elevation) of 99 mph and a gust to 121 mph at 1921 UTC July 10.

Storm-total rainfalls in excess of 23 inches occurred on both Cuba and Jamaica. Heavy rainfall also occurred over much of Florida and extended well inland over portions of the southeastern United States with the maximum amount of 12.80 inches near Camden, Alabama. Ten tornadoes were reported in association with Dennis in the United States.

Dennis caused 42 deaths - 22 in Haiti, 16 in Cuba, 3 in the United States, and 1 in Jamaica. The hurricane caused considerable damage across central and eastern Cuba as well as the western Florida Panhandle, including widespread utility and communications outages. Considerable storm surge-related damage also occurred near St. Marks, Florida, well to the east of the landfall location. The damage associated with Dennis in the United States is estimated at $2.23 billion. Damage in Jamaica is estimated at 1.9 billion Jamaican dollars* (approximately $31.7 million U. S.).

Hurricane Katrina 2005
Katrina was one of the most devastating hurricanes in the history of the United States. It is the deadliest hurricane to strike the United States since the Palm Beach-Lake Okeechobee hurricane of September 1928. It produced catastrophic damage - estimated at $75 billion in the New Orleans area and along the Mississippi coast - and is the costliest U. S. hurricane on record.

This horrific tropical cyclone formed from the combination of a tropical wave, an upper-level trough, and the mid-level remnants of Tropical Depression Ten. A tropical depression formed on August 23 about 200 miles southeast of Nassau in the Bahamas. Moving northwestward, it became Tropical Storm Katrina during the following day about 75 miles east-southeast of Nassau. The storm moved through the northwestern Bahamas on August 24-25, and then turned westward toward southern Florida. Katrina became a hurricane just before making landfall near the Miami-Dade/Broward county line during the evening of August 25. The hurricane moved southwestward across southern Florida into the eastern Gulf of Mexico on August 26. Katrina then strengthened significantly, reaching Category 5 intensity on August 28. Later that day, maximum sustained winds reached 175 mph with an aircraft-measured central pressure of 902 mb while centered about 195 miles southeast of the mouth of the Mississippi River. Katrina turned to the northwest and then north, with the center making landfall near Buras, Louisiana at 1110 UTC August 29 with maximum winds estimated at 125 mph (Category 3). Continuing northward, the hurricane made a second landfall near the Louisiana/Mississippi border at 1445 UTC with maximum winds estimated at 120 mph (Category 3). Weakening occurred as Katrina moved north-northeastward over land, but it was still a hurricane near Laurel, Mississippi. The cyclone weakened to a tropical depression over the Tennessee Valley on 30 August. Katrina became an extratropical low on August 31 and was absorbed by a frontal zone later that day over the eastern Great Lakes.

Katrina brought hurricane conditions to southeastern Louisiana, southern Mississippi, and southwestern Alabama. The Coastal Marine Automated Network (C-MAN) station at Grand Isle, Louisiana reported 10-minute average winds of 87 mph at 0820 UTC August 29 with a gust to 114 mph. Higher winds likely occurred there and elsewhere, as many stations were destroyed, lost power, or lost communications during the storm. Storm surge flooding of 25 to 28 feet above normal tide level occurred along portions of the Mississippi coast, with storm surge flooding of 10 to 20 feet above normal tide levels along the southeastern Louisiana coast. Hurricane conditions also occurred over southern Florida and the Dry Tortugas. The National Hurricane Center reported sustained winds of 69 mph at 0115 UTC August 26 with a gust to 87 mph. Additionally, tropical storm conditions occurred along the northern Gulf coast as far east as the coast of the western Florida Panhandle, as well as in the Florida Keys. Katrina caused 10 to 14 inches of rain over southern Florida, and 8 to 12 inches of rain along its track inland from the northern Gulf coast. Thirty-three tornadoes were reported from the storm.

Katrina is responsible for approximately 1200 reported deaths, including about 1000 in Louisiana and 200 in Mississippi. Seven additional deaths occurred in southern Florida. Katrina caused catastrophic damage in southeastern Louisiana and southern Mississippi. Storm surge along the Mississippi coast caused total destruction of many structures, with the surge damage extending several miles inland. Similar damage occurred in portions of southeastern Louisiana southeast of New Orleans. The surge overtopped and breached levees in the New Orleans metropolitan area, resulting in the inundation of much of the city and its eastern suburbs. Wind damage from Katrina extended well inland into northern Mississippi and Alabama. The hurricane also caused wind and water damage in Miami-Dade and Broward counties.

Hurricane Rita 2005
Rita, the third Category 5 hurricane of the season, was a destructive and deadly hurricane that devastated portions of southeastern Texas and southwestern Louisiana and significantly impacted the Florida Keys.

A tropical wave and the remnants of an old front combined to produce and area of disturbed weather on 16 September. This system became a depression just east of the Turks and Caicos Islands late on 17 September, which moved westward and became a tropical storm the following afternoon. Maximum winds increased to 70 mph as Rita moved through the central Bahamas on September 19. While the storm did not strengthen during the following night, rapid intensification began on September 20 as it moved through the Straits of Florida. Rita became a hurricane that day and reached Category 2 intensity as the center passed about 50 miles south of Key West, Florida.

After entering the Gulf of Mexico, Rita intensified from Category 2 to Category 5 in about 24 hours. The maximum sustained winds reached 165 mph late on September 21, and the hurricane reached a peak intensity of 180 mph early on September 22. Weakening began later that day and continued until landfall around 0740 UTC 24 September just east of the Texas/Louisiana border between Sabine Pass and Johnson's Bayou. At that time, maximum sustained winds were 115 mph (Category 3). Weakening continued after landfall, but Rita remained a tropical storm until reaching northwestern Louisiana late on 24 September. The cyclone then turned northeastward and merged with a frontal system two days later. Rita brought hurricane conditions to southwestern Louisiana and southeastern Texas. A FCMP instrumented tower at Port Arthur reported 1-min average winds of 94 mph at 0826 UTC September 24 along with a gust of 116 mph. The C-MAN station at Sea Rim State Park, Texas reported 2-minute average winds of 82 mph at 0700 UTC September 24, along with a peak gust of 99 mph. The hurricane caused storm-surge flooding of 10 to 15 ft above normal tide levels along the southwestern coast of Louisiana, caused a notable surge on the inland Lake Livingston, Texas, and inundated portions of the New Orleans area previously flooded by Katrina. Tropical storm conditions occurred in the Florida Keys, where the C-MAN station at Sand Key reported 10-minute average winds of 72 mph at 2110 UTC September 20 with a gust to 92 mph. The station failed shortly thereafter. Storm surge flooding of up to 5 feet above normal tide levels occurred in the Keys.

Rita produced rainfalls of 5 to 9 inches over large portions of Louisiana, Mississippi, and eastern Texas, with isolated amounts of 10 to 15 inches. The cyclone spawned an estimated 90 tornadoes over the southern United States.

Devastating storm surge flooding and wind damage in occurred southwestern Louisiana and extreme southeastern Texas, with some surge damage occurring in the Florida Keys. Rita was responsible for seven deaths, and it caused damage estimated at $10 billion in the United States.
