Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
232 AM EDT Sat Oct 4 2025

.SYNOPSIS...

High pressure stretching along the Mid-Atlantic and Carolina coasts
will continue to wedge down the southeastern seaboard, with this
feature expected to gradually weaken today. Gusty east-northeasterly
winds and Small Craft Advisory conditions will continue this weekend
across our local waters, with occasional wind gusts to Gale Force
possible tonight and rough, elevated seas continuing into early next
week. Meanwhile, coastal troughing positioned over our local waters
will continue to generate waves of moderate to heavy showers, with a
few embedded thunderstorms possible. Otherwise, weak low pressure
developing along a frontal boundary over southern Florida will lift
slowly northward this weekend, resulting in increasing coverage of
showers and thunderstorms by Sunday and Monday. Prevailing winds
will shift to easterly on Sunday as high pressure shifts off the
Mid-Atlantic coast, with Small Craft Advisory conditions and
rough, elevated seas extending into next week.
