The first named storm of the 2013 Atlantic Hurricane Season has formed in the eastern Gulf of Mexico. Its name is Tropical Storm Andrea. After days of fighting wind shear, the disturbance in the Gulf was able to become organized enough to become a tropical storm with winds of 40 mph and a central pressure of 1002 mb.
Andrea is slowly moving north at around 3 mph. The storm’s center is on the western most fringe of the blues (the darker the blue, the higher the clouds. The oranges are the ocean and land). So most of the convection and storms are on the western side of the center of circulation, which means this is a pretty weak storm system. It’s not exactly a healthy tropical storm and won’t have the time to get its act together. Andrea is expected to remain a tropical storm over the next 24 hours before it makes landfall in Florida late tomorrow. Tropical Storm warnings are out for much of the central western coast of the state.
There will be a surge of around 2-4’ for the Tampa Bay area, so really nothing major. The main threat from Andrea will be heavy rain and the risk of flooding. The National Weather Service is forecasting a good 3-6” of rain with some locations maybe approaching as much as 8”.
As you can see by the forecast, Andrea will pick up speed and bring heavy rain up and down the East Coast before finally heading out to see.
