AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 310 Am Edt Sun Apr 28 2024
Synopsis..
high pressure building southward towards the carolina coastline this morning will gradually weaken as it becomes situated off the southeastern seaboard early this week. Breezy easterly winds and elevated seas will diminish tonight, with prevailing winds becoming southeasterly on Monday and then southerly on Tuesday. A weakening frontal boundary entering the southeastern states on Tuesday could develop isolated showers and Thunderstorms during the afternoon and evening hours. Atlantic high pressure will then build westward from bermuda later this week, resulting in prevailing southeasterly winds. Another frontal boundary will enter the southeastern states next weekend, possibly resulting in increasing chances of showers and Thunderstorms throughout our local waters.
