This is Tim Roche in for Dr. Masters.
Tropical Storm Delta was classified as a tropical storm as of the 4:00pm EST update from the National Hurricane Center. Delta formed out of a non-tropical low pressure system that has been slowly aquiring tropical characteristics, while drifting eastward over the Atlantic since the middle of last week. Convection wrapped almost all the way around the center earlier today, and a recent Quikscat pass showed several areas with uncontaminated 50kt wind vectors. The system is forecast to drift southward for the next few days then to accelerate northward and lose its tropical characteristics. As Delta becomes extratropical, it will likely strengthen more, with winds possibly reaching hurricane strength. Delta shouldn't effect any landmasses as a tropical storm, and is mostly a threat to nautical interests.Figure 1.
