Former Potential Tropical Cyclone Seven developed a distinct center of circulation on Sunday morning and the National Hurricane Center upgraded the system to Tropical Storm Gordon. At 8:30 a.m. EDT on Sunday the center of Tropical Storm Gordon was located at latitude 25.1°N and longitude 80.6°W which put it about 10 miles (15 km) west of Key Largo, Florida. Gordon was moving toward the west-northwest at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 1009 mb.
A Tropical Storm Warning was in effect for the portion of the coast from Golden Beach to Bonita Beach, Florida. A Tropical Storm Warning was in effect for the Florida Keys from Craig Key to Ocean Reef including Florida bay. A Tropical Storm Warning was in effect for the portion of the coast from the Alabama-Florida border to Morgan City, Louisiana including Lake Pontchartrain.
The circulation of Tropical Storm Gordon became much better organized during the past 12 hours. A distinct low level center of circulation formed and many more thunderstorms developed. A C-MAN station on Fowey Rock, Florida reported sustained winds of 49 m.p.h. (80 km/h) supporting the designation as a tropical storm. The circulation of Tropical Storm Gordon was still organizing. More thunderstorms were developing in bands northeast of the center of circulation than in other parts of the tropical storm. Those storms were beginning to generate upper level divergence which was pumping mass away from the core of Gordon.
Tropical Storm Gordon will be moving through an environment favorable for intensification during the next 36 hours. Gordon will be moving over water where the Sea Surface Temperature is near 30°C. It will be moving through a region where the upper level winds will be weak and there will be little vertical wind shear. Tropical Storm Gordon will continue to intensify and it could intensify more rapidly once the inner core becomes better organized. There is a chance that Gordon could strengthen into a hurricane before it reaches the north coast of the Gulf of Mexico.
Tropical Storm Gordon will move around the west end of a subtropical high pressure system over the western Atlantic Ocean. The ridge will steer Gordon in a general west-northwesterly direction. On its anticipated track Tropical Storm Gordon will move away from South Florida later today. Gordon could approach the north coast of the Gulf of Mexico late on Tuesday. Locally heavy rain could cause floods in South Florida. Tropical Storm Gordon could produce a storm surge of 6 to 9 feet (2 to 3 meters) along parts of the northern Gulf Coast.
