AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 211 Pm Edt Mon Jun 17 2024
Synopsis..
strong high pressure will remain anchored off coastal new england through Thursday. This feature will create gradually increasing onshore winds and building seas across our local waters, with caution conditions expected tonight and then small craft advisory conditions developing offshore by Tuesday afternoon. Meanwhile, a trough situated to the northeast of the bahamas will be steered westward towards the southeastern seaboard late this week, with weak low pressure possibly developing as this system traverses the gulf stream waters. Showers and Thunderstorms are expected to increase in coverage late this week and through the upcoming weekend across our local waters. High pressure will weaken late this week as it sinks slowly southward towards bermuda, with the axis of this surface ridge extending across our area during the upcoming weekend. Winds and seas will gradually diminish as prevailing winds shift to southeasterly on Saturday and then southerly by Sunday.
