Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
858 PM EST Sat Feb 22 2025

.SYNOPSIS...

High pressure over the southeastern states will weaken as it
shifts northeastward towards the coastal Carolinas by Sunday
evening as weak low pressure over the western Gulf of Mexico
slowly organizes and shifts east-southeastward towards the
Florida peninsula towards Monday afternoon. This feature will
spread showers across our local waters from Sunday night through
early Tuesday morning, with a few thunderstorms possible for the
offshore waters adjacent to northeast Florida on Monday and Monday
evening. Low pressure will then cross south Florida and the Keys
on Monday evening before pivoting northeastward across the
northwestern Bahamas on Tuesday morning. This feature will then
strengthen as it accelerates northeastward towards Bermuda on
Tuesday night. Weak high pressure will then build along the
northern Gulf Coast in the wake of this departing low pressure
center on Tuesday and Tuesday night, becoming centered directly
over our local waters on Wednesday. High pressure will then shift
eastward off the southeastern seaboard by Wednesday afternoon and
evening, with southwesterly winds developing ahead of an
approaching cold front that will move southeastward, crossing our
area on Thursday night, likely accompanied by showers through
early Friday morning.
