Tropical Storm Gordon

[edit]
Tropical storm (SSHWS)
 
DurationSeptember 3 – September 6
Peak intensity70 mph (110 km/h) (1-min);
996 mbar (hPa)

A tropical wave departed the west coast of Africa on August 26 and moved quickly across the tropical Atlantic with little convective activity.[1] On August 30, an increase in cloudiness and showers occurred as the wave approached the Caribbean Sea, at which time the NHC began monitoring it for tropical cyclone development.[2] Gradual organization occurred as the system moved northwestward toward the Bahamas, and at 18:00 UTC on September 2, it was designated Potential Tropical Cyclone Seven, as it was forecasted to impact land areas as a tropical storm within two days.[3] At 06:00 UTC the following day, a tropical depression developed from the disturbance, and just three hours later it strengthened into Tropical Storm Gordon.[1] Moving west-northwestward to northwestward around a strong subtropical ridge, Gordon continued to quickly strengthen, reaching an initial peak intensity with sustained winds of 50 mph (85 km/h) as it made landfall near Tavernier, Florida at 11:15 UTC.[1] After making a second landfall near Flamingo at 13:15 UTC, Gordon emerged into the Gulf of Mexico. An eye-like feature briefly appeared late on September 3 as the small tropical cyclone continued to strengthen. At 18:00 UTC on September 4, Gordon reached its peak intensity with maximum sustained winds of 70 mph (110 km/h), making landfall at that intensity at 03:15 UTC the following day near the Alabama-Mississippi border.[1] The tropical storm quickly weakened to a tropical depression at 12:00 UTC, degenerating into a remnant low at 18:00 UTC on September 6 near Pine Bluff, Arkansas.[1] The remnant low degenerated into a trough early on September 8 before merging with a developing extratropical low later that day.[1]

Tropical Storm Nadine

[edit]
Tropical storm (SSHWS)
 
DurationOctober 9 – October 12
Peak intensity65 mph (100 km/h) (1-min);
995 mbar (hPa)

Early on October 6, a tropical wave moved off the west coast of Africa. The wave soon fractured as it moved into the tropical Atlantic, with the northern portion moving over cool waters and the southern portion continuing westward over warm waters.[4] Convection associated with the southern portion increased and became more organized, and a well-defined circulation developed on October 7, at which time the NHC began monitoring it for tropical cyclone development.[5] The disturbance continued to organize over the next day as a well-defined surface low developed. At 06:00 UTC on October 9, while located southwest of Cape Verde, the disturbance organized into a tropical depression, and six hours later strengthened into Tropical Storm Nadine.[4]. Upon its designation as a tropical storm at the longitude of 30°W, Nadine became the easternmost named storm to develop in the tropical Atlantic so late in the calendar year.[6] Located within a very favorable environment with low wind shear, warm sea surface temperatures, and abundant atmospheric moisture, the small tropical cyclone quickly intensified, reaching its peak intensity with maximum sustained winds of 65 mph (100 km/h) around 06:00 UTC on October 10.[4] At that time, a well-defined eye feature was evident in microwave imagery. However, an abrupt increase in westerly wind shear brought an end to the strengthening trend, and Nadine began to weaken later that day. Turning sharply west-northwestward, Nadine encountered hostile environmental conditions which resulted in the cyclone weakening to a tropical depression at 18:00 UTC on October 12.[4] The weakening cyclone degenerated into an open wave six hours later.[4] The wave continued to move westward for the next several days, finally dissipating just east of the Lesser Antilles early on 16 October.[4]
