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 Gaston was a minimal hurricane that made landfall in South Carolina on August 29, 2004. It then crossed North Carolina and Virginia before exiting to the northeast and dissipating. The storm killed nine people – eight of them directly – and caused $130 million (2004 USD) in damage. Gaston produced torrential downpours that inundated Richmond, Virginia. Although originally designated a tropical storm, Gaston was reclassified as a hurricane when post-storm analysis revealed it had maximum sustained winds of 75 mph (120 km/h).
Tropical Storm Hanna was a moderately strong tropical storm that affected the Gulf Coast and Southeastern regions of the United States. The ninth tropical cyclone and eighth named storm of the 2002 Atlantic hurricane season, Hanna formed through the complex interaction of a surface trough, a tropical wave, and an upper-level low pressure system, a disturbance in the upper atmosphere. Designated a tropical depression at 0000 UTC on September 12, the storm remained disorganized throughout its duration, though it attained tropical storm status and a peak intensity of 1,001 mbar (29.6 inHg), with winds of 60 miles per hour (100 km/h). Hanna crossed extreme southeastern Louisiana, and made a second landfall along the Alabama–Mississippi border.
Tropical Storm Alberto was the first tropical storm of the 2006 Atlantic hurricane season. Forming on June 10 in the northwestern Caribbean, the storm moved generally to the north, reaching a maximum intensity of 70 mph (110 km/h) before weakening and moving ashore in the Big Bend area of Florida on June 13. Alberto then moved through eastern Georgia, North Carolina, and Virginia as a tropical depression before becoming extratropical on June 14.
Tropical Storm Barry was a rapidly forming tropical cyclone that made landfall on Florida, United States, in early June 2007. The second named storm of the 2007 Atlantic hurricane season, Barry developed from a trough of low pressure in the southeastern Gulf of Mexico on June 1. It tracked rapidly northeastward, reaching peak winds of 60 mph (97 km/h) before weakening and making landfall near Tampa Bay as a tropical depression. Barry quickly lost tropical characteristics after wind shear removed much of the convection, and early on June 3, it completed the transition into an extratropical cyclone. The extratropical remnants tracked up the East Coast of the United States, and were absorbed by a larger extratropical cyclone on June 5.
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 Storm Erin was a minimal tropical storm that made landfall in Texas in August 2007. The storm's remnants also unexpectedly restrengthened over Oklahoma, causing damage there as well. The second tropical cyclone to make landfall in the United States in the 2007 Atlantic hurricane season and the fifth named storm of the year, Erin formed in the Gulf of Mexico on August 14 from a persistent area of convection. It attained tropical storm status the next day, and on August 16, 2007, Erin made landfall near Lamar, Texas, and persisted over land across Texas before moving northward into Oklahoma. Due to the brown ocean effect, Erin intensified after landfall. The storm resulted in sixteen fatalities and worsened an already-severe flooding issue in Texas.
Tropical Storm Arthur was the first tropical cyclone and named storm of the annual Atlantic hurricane season that caused minimal flooding in the Carolinas in mid-June 1996. Arthur originated from an area of increased convection east of the Bahamas on June 16. Gradually, the system increased in organization, and was designated as a tropical depression on June 17. The depression tracked north-northwest and became Tropical Storm Arthur while just offshore the Southeastern United States on June 19. Later that day, Arthur peaked with maximum sustained winds of 45 mph (75 km/h), but weakened slightly before making landfall in North Carolina early the following day. After striking North Carolina, Arthur tracked out to sea and weakened further to a tropical depression. By June 21, Arthur transitioned into an extratropical cyclone. Overall, impact from Arthur was minimal, limited to light rainfall and moderate surf in North and South Carolina, as well as a tornado in Florida. Total damage amounted to $1 million (1996 USD), but no fatalities were reported.
Hurricane Ida was the strongest landfalling tropical cyclone during the 2009 Atlantic hurricane season, crossing the coastline of Nicaragua with winds of 80 mph (130 km/h). The remnants of the storm became a powerful nor'easter that caused widespread damage along coastal areas of the Mid-Atlantic States. Ida formed on November 4 in the southwestern Caribbean, and within 24 hours struck the Nicaragua coast with winds of 80 mph (130 km/h). It weakened significantly over land, although it restrengthened in the Yucatán Channel to peak winds of 105 mph (170 km/h). Hurricane Ida weakened and became an extratropical cyclone in the northern Gulf of Mexico, before spreading across the southeastern United States. The remnants of Ida contributed to the formation of a nor'easter that significantly affected the eastern coast of the United States.
The 2009 Atlantic hurricane season was a below-average Atlantic hurricane season that produced eleven tropical cyclones, nine named storms, three hurricanes, and two major hurricanes. It officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's first tropical cyclone, Tropical Depression One, developed on May 28, while the final storm, Hurricane Ida, dissipated on November 10. The most intense hurricane, Bill, was a powerful Cape Verde-type hurricane that affected areas from the Leeward Islands to Newfoundland. The season featured the lowest number of tropical cyclones since the 1997 season, and only one system, Claudette, made landfall in the United States. Forming from the interaction of a tropical wave and an upper-level low, Claudette made landfall on the Florida Panhandle with maximum sustained winds of 45 mph (70 km/h) before quickly dissipating over Alabama. The storm killed two people and caused $228,000 in damage.
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.
