Marine Zone Forecast

Synopsis: A weakening cold front will approach the Georgia waters late this afternoon, possibly bringing a few showers and thunderstorms to the waters north of St. Augustine late this afternoon through the early evening hours tonight. Otherwise, breezy south southwesterly winds today will shift to west northwesterly in the wake of the frontal passage after midnight tonight. Weak high pressure will shift over the southeastern states on Sunday as the frontal boundary stalls over the Florida peninsula on Sunday, with onshore winds developing during the afternoon hours. The stalled front over the Florida peninsula on Sunday will then lift northward on Monday before dissipating on Monday night, with a few showers and possibly an isolated thunderstorm developing over our local waters on Monday afternoon and evening. High pressure will then become centered near Bermuda and will extend its axis southwestward across our region on Tuesday and Wednesday, resulting in prevailing south-southeasterly winds. Another cold front will approach our local waters late in the week.
