Coastal Waters Forecast for Northeast Florida/Southeast Georgia

National Weather Service Jacksonville FL

Small Craft Advisory conditions develop this morning ahead of a strong cold frontal boundary which will push into the local waters this afternoon. Strong to severe thunderstorms are forecast to impact our local waters this afternoon, with the potential for damaging wind gusts, waterspouts, and large hail. Winds will shift to westerly following the passage of the strong cold front, with strong northwesterly winds forecast tonight and Tuesday morning throughout our local waters with gale force gusts possible as high pressure builds into the southeastern states. Winds will shift to northerly on Tuesday afternoon and then northeasterly by Wednesday as high pressure shifts northeastward towards the Mid-Atlantic coast. This strengthening high pressure center will wedge down the southeastern seaboard later this week, creating another round of Small Craft Advisory conditions on Wednesday night and Thursday. Winds and seas are expected to diminish by Friday afternoon.
