AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 240 Am Edt Mon Jun 16 2025
Synopsis..
the atlantic high pressure ridge will continue to extend its axis westward across the florida peninsula this week, keeping a prevailing south to southwest wind flow across our area. Showers and Thunderstorms will impact our local waters during the afternoon and evening hours, with isolated strong storms possible, bringing briefly gusty winds, frequent lightning strikes, and torrential downpours. Rain chances will decrease for the local waters Tuesday through Thursday. A weak front enters the southeast states late this week, resulting in increasing chances for afternoon and evening Thunderstorms by Friday and Saturday.
