AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 815 Am Est Fri Nov 7 2025
Synopsis..
the stalled frontal boundary over the northern georgia waters will lift northward as a warm front today, with light onshore winds prevailing across our local waters. Southwesterly winds will develop on Saturday ahead of a strong cold front that will be entering the southeastern u.s. Isolated showers will be possible ahead of this front on Sunday afternoon and evening. This strong front will cross our local waters during the overnight and predawn hours on Monday, with westerly winds strengthening after midnight and then shifting to northwesterly by Sunrise, with small craft advisory conditions quickly overspreading our local waters. Strong high pressure building into the southeastern states on Monday will result in occasional gale force wind gusts through Monday night. High pressure will shift eastward and will become centered directly over our local waters by midweek, allowing for winds and seas to gradually diminish.
