MID ATLANTIC STATES WATERS

SYNOPSIS...A long duration gale event, with winds opposing the Gulf Stream current, is expected to dominate most of the waters today into early next week. This strong counterflow to the Gulf Stream will create large, very steep, and possibly breaking waves resulting in a particularly hazardous sea state. Low pressure NE of the northern waters will move NE away from the area today. A strong cold front extends SW from the low over the far eastern portions of the southern offshore waters early today, with a weak low located along the front over these waters. The cold front will progress slowly to the E and SE today, and shift SE of the area by tonight. Strong high pressure will build to the N and NW of the front into Sun night, then remain nearly stationary W of the area Mon and Mon night. The high will weaken and drift S to the SE states Tue and Tue night, and then drift E off the coast Wed and Wed night. Hurricane Teddy is forecast to move to 33.1N 61.6W at 8 AM EDT Mon, to 37.1N 61.2W at 8 PM EDT Mon, to 40.8N 61.8W at 8 AM Tue, then continue N during Tue night into Wed while becoming a post-tropical cyclone and moving inland over Nova Scotia and Newfoundland Tue night into Wed. Long period E and SE swell from Teddy will move into the waters tonight, and persist into next week. For details on Teddy please see the latest information from the National Hurricane Center.
