Subtropical Storm Andrea Forms in the Southwest Atlantic



Disturbed weather that has been sitting between the Bahamas and Bermuda has become better organized and for the 5th year in a row we are seeing a tropical or subtropical storm before the official start of hurricane season which is June 1st. Andrea can be seen and the satellite picture below as that bright white ball of convection stands out. An Air Force Recon found 40 mph winds and a well defined low level circulation center.

Early storms usually have very short shelf lifes and this one will be gone in a couple of days. The cold front moving offshore tonight over us with low pressure moving across New England will eventually absorb this system, probably sometime on Wednesday. In the meantime the storm is southwest of Bermuda and should pass south of the island based on the forecast track and what is going on in the upper air.
