Rough Surf, Breakers 6-9 ft High Surf Advisory - Moderate Tidal Flooding through Monday: St. Johns River Basin.Extended duration of tidal flooding for St. Johns River next week. Minor Impacts at coast & ICW - Small Craft Advisory Conditions through Monday && .UPDATE... Issued at 735 AM EDT Sun Oct 12 2025 Less wind and warmer today with some wrap-around clouds working their way southward across GA where occasional drizzle or very light showers will be possible today, mainly along and north of a Homerville to Waycross to Brunswick line. Dry conditions for northeast Florida. Mid level clouds increase across northeast Florida late afternoon into the evening, with a low chance of drizzle or very light showers shifting toward the JAX metro area overnight ahead of a wake trough rotating southward around the low offshore of the Carolinas. High temperatures will range from the low/mid 70s across southeast GA where more clouds linger to near 80 south of the Interstate 10 corridor where sunshine will prevail through much of the afternoon. && .NEAR TERM...(Today and Tonight)... Nor`easter conditions are quickly waning and will continue to due so today as the coastal low off the Carolina coast moves farther northeast. Though winds have weakened elevated tides are expected to result in minor flooding this afternoon along the Atlantic coast while moderate flooding continues within the St Johns River basin for the next few days. There will be a dry period this morning as wake northwesterly flow becomes established across the area. However, moisture wrapping back around the low will lead to drizzle and periods of light rain, mainly across southeast GA this afternoon and evening. That light drizzle may make its way toward the Jacksonville area around sunset and linger through the evening before moisture is scoured out by incoming dry area to the west overnight. A bit more sunshine across portions of northeast FL will allow highs to push into the low 80s but lingering cloud cover over southeast GA will keep temperatures cooler, reading in the mid 70s, this afternoon. Clearing skies tonight and lighter winds will lead to good radiational cooling with inland lows falling to the mid/upper 50s and low/mid 60s at the coast. && .SHORT TERM...(Monday through Tuesday night) Dry air and high pressure will continue to settle in across the forecast area on Monday and Tuesday as the area of low pressure moves off to the northeast, with partly cloudy to mostly clear skies along transitioning to mostly clear by the end of the period. High daytime temperatures will reach into the lower 80s for the beginning of the week with overnight low temperatures dropping down into the mid to upper 50s for inland areas and in the lower to mid 60s along the shoreline and for areas along the St Johns River. && .LONG TERM...(Wednesday through Saturday) Dry weather with mostly clear skies are expected to remain prevalent for midweek through Saturday as drier air associated with high pressure remains in place over the region through the majority of the forecast period. High temperatures will trend near the seasonal average through the rest of the week and into the weekend, with initially cool overnight low temperatures warming to be closer to average levels by Saturday. && .AVIATION... (12Z TAFS) Issued at 735 AM EDT Sun Oct 12 2025 Increasing mid clouds toward SSI with light drizzle near the terminal through much of the forecast period under WNW winds which will increase to 10-12 kts by 14z with gusts near 20 kts through much of the day. Include TEMPO MVFR based on upstream obs through 14z of lower stratus, then prevailing MVFR late afternoon into the evening with IFR possible after 00z. Prevailing VFR today at northeast Florida terminals as WNW develops with speeds 8-12 kts and gusts 18-22 kts in the afternoon. Some increase in mid and low level clouds from the WNW toward 00z with light drizzle or showers near JAX, CRG and VQQ through 06z. && .MARINE... Winds continue to decrease across the local waters but Small craft advisory conditions will persist through Monday due to lingering elevated combined seas. High pressure builds north of the region Tuesday and Wednesday, with a bout of breezy northeast winds trailing a dry frontal passage. Rip Current & High Surf: A high rip current risk continues for all local beaches today. The high surf advisory may be trimmed southward today after morning break height reports are received. && .HYDROLOGY... Moderate tidal flooding impacts over the next couple of days will continue to focus in the St. Johns River Basin between downtown Jacksonville (Main Street Bridge) southward to Lake George where high tide inundation will peak between 2.0-2.5 ft MHHW with trapped tides. The amplitude of peak tides will slowly dampen over the coming days. Offshore WNW flow will reduce the tidal flooding threat today with peak inundation still expected to reach minor flooding levels of 1.5 to 2 ft MHHW around the afternoon high tide (1 pm - 2 pm) for the coast. A coastal flood advisory remains in place for the coast today. The area of exception for the coastal tidal flooding will be the Intracoastal Waterway, especially in St. Johns and Flagler counties where localized Moderate Tidal flooding is expected with inundation of 2-2.3 ft MHHW - but not as high as yesterday`s peak tide for this event. Northeast winds return midweek which may prolong minor or elevated tidal flooding through the upcoming week. && .PRELIMINARY POINT TEMPS/POPS...
