Meteorological Analysis
|
Tammy originated from a tropical wave which left the African coast on September 24th. The
wave was vigorous at first but, quickly lost its convection. The wave then crossed the ocean
without causing much suspicion. On October 2nd however, the wave interacted with a trough
just north of the Leeward Islands and gained convection. As convection increased on the 3rd
and 4th, a sharp surface trough formed. This surface feature was not closed however, wind
shear kept the feature from closing off at this point. The whole system continued as a
messy rain maker towards Florida, and the gradient between it and the trough caused gale
force winds. On October 5th, deep convection formed and a surface low was indicated to
be developing under this convection. Since the storm already possessed gale force winds, the
storm was upgraded directly to tropical storm Tammy later in the day, it was about 20 nm
from Jupiter. Tammy strengthened to 50 mph as it headed NW towards the Florida coast
under the influence of a low pressure in the Gulf of Mexico. Tammy made landfall near
Atlantic Beach, Florida on the 5th, and degenerated into a depression on the 6th over
Georgia. Tammy was absorbed by an extra-tropical low as it meandered over the Florida
Panhandle on the 7th.

Casualty and Damage Overview
|
Heavy rainfalls of 3-5 inches, and up to 10 inches in south east Georgia caused some
damage. 2-4 feet of storm surge came ashore from Florida to South Carolina also,
causing damages mostly in the form of beach erosion. One F0 tornado caused damage
in Brunswick, Georgia on the 5th. Total damages were less than $25 million in the U.S.
