On Wednesday, the precipitation surrounding the center of this storm was diminishing and the NHC actually planned on issuing its last statement on what was then just a special feature.

Convection increased with the system Thursday as it was being fed by the Gulf stream, which is basically a thin stream of warm water.

Since the storm will be in an environment where wind shear will be weak, the Hurricane Center is forecasting it to become a tropical storm (Ana) by Friday.

It has already become the first system of 2009, developing four days before the official start of the tropical season.

T.D. One is moving northeastward -- away from the United States -- and will eventually track into the cooler waters of the northern Atlantic. Once this occurs, the storm should fall apart.
