  Weather Forecast
NWS Forecast for: 2NM NNW Mayport FL
Atlantic Ocean

Issued by: National Weather Service Jacksonville, FL
Last Update: 10:16 pm EDT Oct 16, 2018

Synopsis: A slow moving cold front over central Georgia will push across the southeast Georgia waters by late Wednesday afternoon and the northeast Florida waters on Wednesday night. Strong high pressure will build into the Ohio Valley on Thursday and will wedge down the southeastern seaboard, resulting in an abrupt increase in northeasterly winds during the morning hours and Small Craft Advisory conditions through early Friday. High pressure will then move off the Mid-Atlantic coast and will weaken on Friday, with onshore winds and seas gradually diminishing. A strong cold front will then move across our region on Saturday night, with northwesterly winds strengthening after midnight. Onshore winds will quickly develop in the wake of this frontal passage as strong high pressure builds into the Carolinas on Sunday.
Overnight: S wind 10 to 12 kt. Mostly clear. Seas around 1 ft.

Wednesday: SSW wind 7 to 9 kt becoming ESE in the afternoon. A slight chance of showers and thunderstorms after 4pm. Seas around 1 ft.

Wednesday Night: SE wind 5 to 9 kt becoming variable and less than 5 kt after midnight. A slight chance of showers and thunderstorms, then a chance of showers after midnight. Seas 1 ft or less.

Thursday: NE wind 12 to 18 kt, with gusts as high as 25 kt. A chance of showers. Seas 1 to 2 ft.
