Tropical Storm Gordon was a tropical cyclone of moderate intensity that caused damage along the Gulf Coast of the United States in early September 2018. The seventh named storm of the 2018 Atlantic hurricane season, Gordon developed from a tropical wave that was first monitored in the Caribbean Sea on August 30. The wave moved west-northwestward toward the east coast of Florida while gradually organizing. The disturbance was marked as Potential Tropical Cyclone Seven on September 2 while near the Bahamas, and early the next day, it became Tropical Storm Gordon. The system made landfall on the southwest coast of Florida shortly afterwards. Steady intensification began after it moved off the coast of Florida and into the Gulf of Mexico. Gordon reached its peak intensity as a high-end tropical storm late on September 4 before making landfall just east of Pascagoula, Mississippi shortly afterwards. Gordon then rapidly weakened as it tacked inland, and degenerated into a remnant low on September 6. Gordon's remnants lingered over Arkansas for two days, before opening up into a low-pressure trough on September 8. At least three deaths were attributed to the storm, and Gordon caused approximately $200–250 million (2018 USD) in damages,[1] making it the third-costliest tropical cyclone in the United States for the 2018 season.

Meteorological history[edit]

On August 30, 2018, the National Hurricane Center (NHC) began monitoring a tropical wave over the north-central Caribbean Sea for tropical cyclone formation. Development was expected to be slow to occur due to unfavorable upper-level winds, although the environment was expected to become more favorable once the disturbance reached the Gulf of Mexico.[2] The tropical wave began to organize after leaving the Caribbean Sea on September 1. Due to its threat to the United States and an increasing organization trend, the NHC initiated advisories on the nascent system late on September 2, designating it as Potential Tropical Cyclone Seven.[3] Early the following day, the disturbance developed a closed circulation and well-defined center while it was situated off the coast of Florida, and the system was classified as a tropical storm by the NHC. It was subsequently assigned the name Gordon.[4] Shortly afterwards, the storm's center passed over Key Largo, Florida.

Shortly after Gordon moved offshore from Florida, a small eye became apparent on radar imagery, although it was soon eroded, and the surrounding convection became somewhat ragged.[5] The structure of Gordon's small core continued to deteriorate throughout the evening as light to moderate westerly shear affected the system, although the storm continued to intensify.[6] Gordon soon began to organize once again, however, with lightning activity increasing in the inner core and a band of deep convection developing very near the center.[7] Gordon moved northwest through the Gulf of Mexico, in the general direction of New Orleans. The system was expected to intensify into a Category 1 hurricane shortly before landfall,[8][9][10][11][12] and hurricane warnings were issued accordingly for Mississippi and Alabama.[13] Ultimately, however, Gordon did not intensify into a hurricane before making landfall near the Mississippi–Alabama border. The system attained a peak sustained wind speed of 70 mph (110 km/h) at 10:00 p.m. CDT, September 4—at the upper limit of tropical storm strength.[14] Rapid weakening occurred on September 5 as Gordon moved further inland and meandered around the state of Arkansas, and the system degenerated into a remnant low the following day. On September 8, the remnants of Gordon weakened into a low-pressure trough, and were absorbed by a developing extratropical cyclone a few hours later.[1] The new extratropical low moved northeastward for the next few days, producing more rainfall over the region, before dissipating on September 11.[1]

Preparations and impact[edit]

Rainfall associated with Gordon and its extratropical remnants

Florida[edit]

Tropical Storm Gordon formed near the Florida Keys and brought tropical-storm-force winds to southern Florida. Governor Rick Scott of Florida urged Floridians to prepare and "remain vigilant."[15][16] Shortly afterwards, a hurricane warning was issued in Mississippi and Alabama, with tropical-storm warnings extending around it into Louisiana and the Florida Panhandle.[17] Several locations in southern Florida observed tropical-storm-force winds gusts, including a gust of 51 mph (82 km/h) in Opa-locka. More than 8,000 people were left without electricity in Broward and Miami-Dade counties. One death occurred in Miami on Interstate 95 when a truck driver lost control of his vehicle, crashed into a wall, and was ejected from the truck.[18][19] A second death was reported after a tree crushed a mobile home in Pensacola, killing a child inside.[14] Gusty winds were also reported in the Panhandle, with Pensacola receiving wind gusts to 61 MPH.[20] Rainfall was also significant in Escambia County, Florida, with rainfall totals of up to 10 inches in the Pensacola and Gulf Breeze area.[21]

Alabama[edit]

Dauphin Island, Alabama bore the brunt of Gordon. A storm surge of 3–5 ft (0.9–1.5 m) struck the island, causing minor flooding.[22] A one-minute sustained wind of 67 mph (108 km/h) and a peak gust of 74 mph (119 km/h) were also reported there. Homes on the island sustained roof and siding damage.[1] Tropical-storm-force winds penetrated inland as far as Mobile Regional Airport, downing trees in areas of southern Mobile County.[23] Farther inland, 5–8 in (130–200 mm) of rainfall caused flooding along several rivers, inundating streets and washing out dirt roads.[24]

Louisiana[edit]

Louisiana Governor John Bel Edwards declared a state of emergency for the state, deploying 200 Louisiana National Guardsmen, 63 high-water trucks, 39 boats, and four helicopters.[25] Mississippi Governor Phil Bryant and Alabama Governor Kay Ivey also declared states of emergencies.[26]

Kentucky[edit]

A Louisville cab driver was killed after being trapped by flood waters.[27] More than 3 inches (75 mm) of rain fell in Louisville, flooding streets, stranding cars, and causing the Louisville City FC soccer match to be suspended and the University of Louisville football game to be delayed.[28] In Morehead, a young child was swept in flood water and recovery efforts were ongoing as of September 9, 2018.[29]

Missouri[edit]

On September 7, A Greene County Sheriff's Deputy was killed after his patrol vehicle was washed off of a rural county road at an unmarked low-water crossing at the Pomme de Terre River at the Greene County and Dallas County line during a bout of torrential rains. The deputy had been in the area responding to a 911-hang up call, likely as a result of the weather.[30][31]
