| Area Forecast Discussion National Weather Service Jacksonville FL 547am EST Thu Nov 5 2026 .KEY MESSAGES... For the latest NE FL and SE GA Daily Key Messages please visit: https:/www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf - Localized Dense Fog this Morning and Friday AM - Isolated Thunderstorms this Afternoon between I-75 and US-301 in. Additional Isolated Afternoon Thunderstorm Potential Friday - Minor Tidal Flooding within Portions of the St. Johns River Basin - Moderate Rip Current Risk through the Weekend Marine An advancing cold front entering the southeastern states will slow its forward speed, with prevailing winds shifting to become more southerly today and then southwesterly on Friday and Friday night. Scattered showers and isolated thunderstorms may impact the waters on Friday afternoon and evening ahead of this approaching front, which will cross our local waters before sunrise on Saturday. Winds will shift to northwesterly with increasing speeds after midnight on Friday night, followed by winds shifting to northerly and then northeasterly in the wake of this frontal passage on Saturday afternoon and evening. High pressure will gradually build into the southeastern states on Sunday and Monday, creating breezy northeasterly winds and gradually building seas across our local waters. Rip Currents / High Surf: Onshore winds will weaken on today and shift offshore by Friday. However, a lingering easterly ocean swell will still yield a moderate risk at all area beaches from today and through the upcoming weekend. Fire Weather - Low Dispersions Across Northeast Fl Today Weak southerly transport winds this afternoon will lead to low smoke dispersions across NE FL. Winds will shift southwesterly through Friday ahead of slow-moving and mostly dry cold front, which will push across Friday night, ushering in a drier and cooler airmass over the weekend and into early next week. Critically low humidity is not expected behind the front but a multi-day period of northerly light surface and transport winds will develop. FOG POTENTIAL AND OTHER WEATHER REMARKS: Areas to widespread fog will be possible during the predawn and early morning hours today and again tomorrow (Friday) across the area. Tides / Coastal Flooding Water levels within most of the St. Johns River basin continue to gradually decline with each successive high tide cycle, with gauges now reporting peak levels mostly in the action stage (below minor flooding) from around Racy Point northward. Flood Advisory continues in portions of the river south of Racy Point where tides continue to reach 1.5 to 2 feet above normally dry ground during times of high tide (minor flooding). Recent heavy rainfall over central FL may allow elevated water levels to linger for locations along the St. Johns River and its tributaries near Lake George and Crescent Lake during the next several days as the floodwater drains northward. NOAA Jacksonville FL Office: Watches - Warnings - Advisories FL...Coastal Flood Advisory until 4am EST Friday for FLZ038-137. GA...None. Marine None. |
