A broad area of low pressure is expected to form along this trough Thu night to the southwest of Bermuda, when the trough is forecast to extend from 30N67W to South Florida. Fresh to strong winds may cover a large area with this low as it slides E along a cold front to the S of Bermuda on Fri. At the same time, another broad area of low pressure over the eastern Gulf of Mexico late this week will move E across Florida and into the western Atlantic over the weekend. As a result, increasing winds and building seas are likely between Florida and 60W this weekend. Strong N to NE winds and building seas are expected offshore northeast Florida Sun and Sun night behind a cold front. .OVERNIGHT...E to SE winds 10 to 15 kt. Seas 2 ft or less.
