Maximum sustained winds are 45 kt with gusts to 55 kt, and the minimum central pressure is 994 mb. Tammy will move to 33.0N 58.7W this afternoon, 32.6N 56.0W Sun morning, 31.7N 53.1W Sun afternoon, weaken to a remnant low near 30.4N 50.6W Mon morning, 28.9N 49.5W Mon afternoon, and 27.5N 50.8W Tue morning. Tammy will change little in intensity as it moves to 27.9N 53.1W by early Wed. High pressure across the middle Atlantic coastal states is combining with a low level trough than extends from S of Tammy to the NE Caribbean to produce a large area of fresh to strong winds, with very high seas between Tammy and the Bahamas. These high seas will slowly subside through Sun. Elongated low pressure will develop across the SE Bahamas Sun and gradually drift NW through Tue.
