.MARINE... Sub SCA level southerly winds continue across the local waters this morning with high pressure pushing further offshore. Winds gradually increase Wednesday afternoon and evening especially over northern/middle portions of the bay. Gusts up to 15 kts are expected in these locations this afternoon increasing to around 28 kts late tonight into Thursday morning. This is when the cold front will cross the waters. SCA conditions are likely late tonight and throughout Thursday as winds switch to the west and northwest in the wake of the front. Gusts of 25 to 30 kts can be expected with the highest gusts across the southern waters of the bay/tidal Potomac. Winds diminish Thursday night to below SCA criteria. Sub SCA conditions continue through Friday as winds switch back to the south with brief high pressure building overhead. High pressure pushes offshore Friday night as another strong cold front approaches Saturday. SCA conditions will return as a result with west to northwest winds gusting 20 to 25 kts. Winds diminish Saturday night into Sunday as high pressure builds back over the region. Update as of: 333 AM EDT Wed Oct 23 2024
