Tropical Storm Allison was a tropical storm that devastated southeast Texas in June of the 2001 Atlantic hurricane season. An arguable example of the "brown ocean effect", Allison lasted unusually long for a June storm, remaining tropical or subtropical for 16 days, most of which was when the storm was over land dumping torrential rainfall. The storm developed from a tropical wave in the northern Gulf of Mexico on June 4, 2001, and struck the upper Texas coast shortly thereafter. It drifted northward through the state, turned back to the south, and re-entered the Gulf of Mexico. The storm continued to the east-northeast, made landfall on Louisiana, then moved across the southeast United States and Mid-Atlantic. Allison was the first storm since Tropical Storm Frances in 1998 to strike the northern Texas coastline.
Hurricane Jeanne was a Category 3 hurricane that struck the Caribbean and the Eastern United States in September 2004. It was the deadliest hurricane in the Atlantic basin since Mitch in 1998. It was the tenth named storm, the seventh hurricane, and the fifth major hurricane of the season, as well as the third hurricane and fourth named storm of the season to make landfall in Florida. After wreaking havoc on Hispaniola, Jeanne struggled to reorganize, eventually strengthening and performing a complete loop over the open Atlantic. It headed westwards, strengthening into a Category 3 hurricane and passing over the islands of Great Abaco and Grand Bahama in the Bahamas on September 25. Jeanne made landfall later in the day in Florida just two miles from where Hurricane Frances had struck a mere three weeks earlier.
Hurricane Rita was the most intense tropical cyclone on record in the Gulf of Mexico and the fourth-most intense Atlantic hurricane ever recorded. Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten most intense Atlantic hurricanes in terms of barometric pressure ever recorded, Rita was the seventeenth named storm, tenth hurricane, and fifth major hurricane of the 2005 season. It was also the earliest-forming 17th named storm in the Atlantic until Tropical Storm Rene in 2020. Rita formed near The Bahamas from a tropical wave on September 18, 2005 that originally developed off the coast of West Africa. It moved westward, and after passing through the Florida Straits, Rita entered an environment of abnormally warm waters. Moving west-northwest, it rapidly intensified to reach peak winds of 180 mph (285 km/h), achieving Category 5 status on September 21. However, it weakened to a Category 3 hurricane before making landfall in Johnson's Bayou, Louisiana, between Sabine Pass, Texas and Holly Beach, Louisiana, with winds of 115 mph (185 km/h). Rapidly weakening over land, Rita degenerated into a large low-pressure area over the lower Mississippi Valley by September 26th.
Tropical Storm Tammy was a short-lived tropical storm during October in the 2005 Atlantic hurricane season which caused minor damage to the southeastern United States. More significant, however, were its remnants, which contributed to the Northeast U.S. flooding of October 2005.
Hurricane Cindy was a tropical cyclone that briefly reached minimal hurricane strength in the Gulf of Mexico during July in the 2005 Atlantic hurricane season and made landfall in Louisiana. It was the third named storm and first hurricane of the season. Cindy was originally thought to have been a tropical storm at peak strength, but was upgraded to a Category 1 hurricane in the post-season analysis. Cindy formed on July 3 just east of the Yucatán Peninsula in the Caribbean Sea. The depression soon made landfall on the peninsula and weakened before reemerging in the Gulf of Mexico on July 4. The storm strengthened as it moved north becoming a hurricane just before making landfall near Grand Isle, Louisiana, on July 5. The storm weakened as it moved overland and became extratropical on July 7.
Hurricane Earl was an atypical, disorganized, and short-lived Category 2 hurricane that caused moderate damage throughout the Southeast United States. It formed out of a poorly organized tropical disturbance over the southwest Gulf of Mexico late on August 31, 1998. Tracking towards the northeast, the storm quickly intensified into a hurricane on September 2 and made landfall early the next day near Panama City, Florida. Rapidly tracking towards Atlantic Canada, the extratropical remnants of Earl significantly intensified before passing over Newfoundland on September 6. The remnants were absorbed by former Hurricane Danielle two days later.
Accompanying Hurricane Katrina's catastrophic coastal impacts was a moderate tornado outbreak spawned by the cyclone's outer bands. The event spanned August 26–31, 2005, with 57 tornadoes touching down across 8 states. One person died and numerous communities suffered damage of varying degrees from central Mississippi to Pennsylvania, with Georgia sustaining record monetary damage for the month of August. Due to extreme devastation in coastal areas of Louisiana and Mississippi, multiple tornadoes may have been overlooked—overshadowed by the effects of storm surge and large-scale wind—and thus the full extent of the hurricane's tornado outbreak is uncertain. Furthermore, an indeterminate number of waterspouts likely formed throughout the life cycle of Hurricane Katrina.
The Tornado outbreak sequence of March 9–13, 2006 was an early season and long lasting tornado outbreak sequence in the central United States that started on the morning of March 9 and continued for over four days until the evening of March 13. The outbreak produced 99 confirmed tornadoes, which killed a total of 10 people. The Storm Prediction Center (SPC) issued multiple elavated outlook throughout the sequence, including a rare high risk for March 12, which would end up being the most intense day of the outbreak, producing 62 in total. 11 F3 tornadoes were tallied, and a violent F4 tornado touched down in Monroe County, Missouri, becoming the strongest of the outbreak. Multiple tornado emergencies were issued for tornadoes throughout the outbreak as well. An intense F3 tornado that affected the towns of Renick and Maddison in Missouri killed 4 people and injured dozens others, becoming the deadliest of the sequence. Multiple of the tornadoes were long-tracked in nature, with 6 of them having paths exceeding 30 miles (48 km). One particular supercell thunderstorm during the outbreak persisted for many hours and progressed in excess of 800 miles (1,300 km) through Oklahoma, Kansas, Missouri, Illinois, Indiana, and extreme southern Michigan.
Tropical Storm Bill was a tropical storm that affected the Gulf Coast of the United States in the summer of 2003. The second storm of the 2003 Atlantic hurricane season, Bill developed from a tropical wave on June 29 to the north of the Yucatán Peninsula. It slowly organized as it moved northward, and reached a peak of 60 miles per hour (97 km/h) shortly before making landfall in south-central Louisiana. Bill quickly weakened over land, and as it accelerated to the northeast, moisture from the storm, combined with cold air from an approaching cold front, produced an outbreak of 34 tornadoes. Bill became extratropical on July 2, and was absorbed by the cold front later that day.
Hurricane Humberto was a Category 1 hurricane that formed and intensified faster than any other North Atlantic tropical cyclone on record, before landfall. The eighth named storm and third hurricane of the 2007 Atlantic hurricane season, Humberto developed on September 12, 2007, in the northwestern Gulf of Mexico. The tropical cyclone rapidly strengthened and struck High Island, Texas, with winds of about 90 mph (140 km/h) early on September 13. It steadily weakened after moving ashore, and on September 14, Humberto began dissipating over northwestern Georgia as it interacted with an approaching cold front.
Tropical Depression Ten was a short-lived tropical cyclone that made landfall on the Florida Panhandle in September 2007. The system developed as a subtropical depression on September 21 in the northeastern Gulf of Mexico from the interaction of a tropical wave, the tail end of a cold front, and an upper-level low. Initially containing a poorly defined circulation and intermittent thunderstorm activity, the system transitioned into a tropical depression after convection increased over the center. Tracking northwestward, the depression moved ashore near Fort Walton Beach early on September 22 and dissipated over southeastern Alabama shortly thereafter.
The Hurricane Ivan tornado outbreak was a three-day tornado outbreak that was associated with the passage of Hurricane Ivan across the Southern United States starting on September 15, 2004, across the Gulf Coast states of Alabama and Florida as well as southern Georgia before ending in the Middle Atlantic Coast on September 18.
The Hurricane Cindy (2005) tornado outbreak was a two-day tornado outbreak that was associated with the passage of Hurricane Cindy across the Southern United States starting on July 6, 2005, across the Gulf Coast states of Alabama and Florida as well as Georgia before ending in the Middle Atlantic Coast on early on July 8. The outbreak caused no fatalities and only one injury but was fairly strong, as there were three F2 tornadoes spawned due to Cindy. The hurricane itself killed three people, two in Georgia, one in Alabama. Cindy produced a total of 44 tornadoes across seven states in a two-day span. Just three days after Hurricane Cindy had stuck the Southeastern United States, a much stronger and deadlier storm, Hurricane Dennis, made landfall on the Florida Panhandle on July 10.
Tropical Storm Fay was a strong and unusual tropical storm that moved erratically across the state of Florida and the Caribbean Sea. The sixth named storm of the 2008 Atlantic hurricane season, Fay formed from a vigorous tropical wave on August 15 over the Dominican Republic. It passed over the island of Hispaniola, into the Gulf of Gonâve, across the island of Cuba, and made landfall on the Florida Keys late in the afternoon of August 18 before veering into the Gulf of Mexico. It again made landfall near Naples, Florida, in the early hours of August 19 and progressed northeast through the Florida peninsula, emerging into the Atlantic Ocean near Melbourne on August 20. Extensive flooding took place in parts of Florida as a result of its slow movement. On August 21, it made landfall again near New Smyrna Beach, Florida, moving due west across the Panhandle, crossing Gainesville and Panama City, Florida. As it zigzagged from water to land, it became the first storm in recorded history to make landfall in Florida four times. Thirty-six deaths were blamed on Fay. The storm also resulted in one of the most prolific tropical cyclone related tornado outbreaks on record. A total of 81 tornadoes touched down across five states, three of which were rated as EF2. Damage from Fay was heavy, estimated at $560 million.
The effects of Hurricane Georges in Florida lasted for more than a week in late September and early October in 1998. After developing from a tropical wave to the south of Cape Verde on September 15, Georges moved steadily west-northwestward and peaked as a strong Category 4 hurricane on the Saffir–Simpson scale on September 20. After weakening slightly to a Category 3, the cyclone proceeded to strike Antigua, Saint Kitts and Nevis, Puerto Rico, Dominican Republic, and Cuba. Georges emerged into the Straits of Florida as a Category 1, but re-strengthened slightly to a Category 2 before making landfall in Key West, Florida, on September 25. The hurricane continued northwestward into the Gulf of Mexico and struck near Biloxi, Mississippi, on September 28. After moving inland, Georges turned eastward and crossing into the Florida Panhandle on the next day. By October 1, the system dissipated near the northeast Florida–southeast Georgia coast.
The effects of Hurricane Jeanne in the Mid-Atlantic region of the United States included two fatalities and $530 million in damage. Originating from a tropical wave off the coast of Africa in early September 2004, Hurricane Jeanne tracked through the Leeward Islands and Hispaniola for several days, resulting in extensive damage and an immense loss of life. After completing a clockwise loop between September 22 and 24, the storm intensified into a major hurricane before striking the Bahamas and Florida. Substantially weaker, the system turned northeastward over Georgia before affecting Delaware, District of Columbia, Maryland, New Jersey, New York, Pennsylvania, Virginia, and West Virginia; all of those states are in the Mid-Atlantic region of the United States. By the evening of September 26, the Hydrometeorological Prediction Center took over responsibility of monitoring the former hurricane over Virginia.
From August 18–27, 2008, Tropical Storm Fay produced 50 tornadoes as it meandered across the Southeastern United States.
A destructive outbreak of 14 tornadoes hit the Southeast. Seven of the 14 tornadoes were significant (F2+) and multiple populated areas were struck. Overall, the outbreak injured 11 and caused $460,030 in damage.
