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.
Tropical Storm Tammy formed from a non-tropical system off the Florida coast on October 5. It moved north just offshore before making landfall later that day. The tropical storm rapidly weakened as it moved overland and dissipated the next day. Its remnant circulation moved south towards the Gulf of Mexico, while the moisture was absorbed by a northeasterly moving cold front. There were no fatalities directly related to Tammy; however, ten people were killed by the remnants of the storm in combination with the remnants of Subtropical Depression Twenty-Two. Total damages from the storm were $30 million.
A tropical wave left the western coast of Africa on September 24 and crossed the Atlantic without any development. The wave began to develop on October 2 north of the Lesser Antilles when it encountered an upper level trough. It strengthened as it passed through the Bahamas and early on October 5 a vigorous tropical disturbance formed. As the system already had tropical-storm force winds, it was immediately named Tropical Storm Tammy. Upon being classified, the system was poorly organized, with deep convection only persisting to the northeast of the center of circulation. Tropical storm-force winds were presumed to be located underneath the convection as ship reports nearby the system only reported winds up to 35 mph (55 km/h). Tammy quickly tracked towards the northwest in a southerly flow between a mid to upper-level low over the Gulf of Mexico and a ridge located over the western Atlantic Ocean. Later that day, a reconnaissance flight into the storm recorded flight level winds of 61 mph (98 km/h), which corresponds to surface winds of 50 mph (85 km/h). However, small areas of 60 mph (95 km/h) to 65 mph (100 km/h) were reported by the crew members of the aircraft. At 6:30 pm EST (2300 UTC), the storm made landfall with winds of 50 mph (85 km/h) near Atlantic Beach, Florida. The tropical storm then moved inland over Georgia and into southeastern Alabama near Ozark, where it lost its circulation on October 6.
