An isolated shower or storm is possible this afternoon and evening, mainly south of the Albemarle Sound.

Tropical Update

We are watching a non-tropical low pressure system located about 700 miles south of Cape Race, Newfoundland. Environmental conditions are forecast to become somewhat more conducive for some subtropical or tropical development by Wednesday. The system is forecast to move NE over the colder waters of the North Atlantic by late Thursday or Friday, which should limit any additional development.
