366 FXUS62 KKEY 120240 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1040 PM EDT Sat Oct 11 2025 ...New DISCUSSION, MARINE, AVIATION... .KEY MESSAGES... -A Coastal Flood Advisory remains in effect for all Florida Keys. -First taste of Fall for the Florida Keys behind today`s frontal passage. Drier air filtering in behind will promote rapidly decreasing rain chances into next week. && .DISCUSSION... Issued at 1040 PM EDT Sat Oct 11 2025 Winds all across the Keys and surrounding coastal waters have clocked around to the northwest and north in the wake of today`s frontal passage. The main batch of showers and thunderstorms quickly subsided prior to sunset. Within the last hour, shallow cold air advection showers have been waxing and waning as they slide southeast across the outer Gulf and portions of the Lower Keys. These showers are likely only dropping a hundredth of an inch or two at most. Meanwhile, a Coastal Flood Advisory continues for the Florida Keys through at least one more high tide cycle. Drier air will gradually filter in behind the frontal passage, leading to lower, more comfortable dew points as well as lower rain chances. Given the shallow showers that are being produced by the cold air advection, will leave the 20 percent PoPs for the overnight. Otherwise, northerly winds will persist overnight. There is a chance that we could see a minor nocturnal surge off the mainland and therefore winds have been nudged up slightly. && .MARINE... Issued at 1040 PM EDT Sat Oct 11 2025 Northerly winds will continue to filter in behind the recent frontal passage today. Expect northerly swells across our western marine zones overnight. In the wake of the front, high pressure builds across the eastern United States leading to freshening northeasterly breezes heading towards mid- week. && .AVIATION... (00Z TAFS) Issued at 1040 PM EDT Sat Oct 11 2025 VFR conditions will be the predominant for the overnight. Some shallow showers passing through overnight could bring brief MVFR CIGs but the coverage is not enough to include mentions of VCSH at this time. && .KEY WATCHES/WARNINGS/ADVISORIES...
