716 FXUS62 KKEY 041444 AFDKEY Area Forecast Discussion National Weather Service Key West FL 1044 AM EDT Thu Sep 4 2025 ...New DISCUSSION, MARINE, AVIATION... .DISCUSSION... Issued at 1044 AM EDT Thu Sep 4 2025 Another yucky morning for the Florida Keys. KAMX radar detects widespread showers with scattered thunderstorms throughout the CWA. While a majority of the island chain saw a little break in showers and Key West even saw sunshine for a few minutes, that relief was brief as radar shows a large area of convection moving towards land. The 12z KKEY sounding this morning measured 2.34 inches which is not record breaking, but well above the 90 percentile for the day. Winds across the Reef are currently southwest to west at 10 to 15 knots. Little change is expected today in terms of synoptic pattern resulting in very similar conditions that we`ve been experiencing over the last few days. Therefore, we will see yet another wet day, with a possible lull in the evening before firing off again. For winds, a brief surge of near 15 knots is possible in the coastal waters before settling back to 10 to 15 knots. No changes were needed to this update as everything is on track. && .MARINE... Issued at 1044 AM EDT Thu Sep 4 2025 No watches, warnings, or advisories are currently in effect for the coastal waters of the Florida Keys. From synopsis, a broad surface low along a stationary front stretching from the Gulf eastward to the Florida Peninsula will maintain westerly winds across the Florida Keys marine zones today. The front will remain rooted in place through the next few days, while the low meanders northeast into the western North Atlantic, promoting southwest to west breezes throughout the week. Abundant moisture will promote well above normal rain and thunder chances through the end of the work week. High pressure slowly building across the North Atlantic over the weekend will support reduced rain and thunder chances, although remaining at or above normal. && .AVIATION... (15Z TAFS) Issued at 1044 AM EDT Thu Sep 4 2025 Though VFR conditions are prevailing at both terminals, a large area of showers with embedded thunderstorms is moving towards the island chain. TEMPOs may be required for passing thunderstorms including lower VIS, CIG, and gusty winds associated. Outside of direct impacts, VCSH is included at EYW and MTH and will likely stay that way through tonight and winds will be southwest to westerly at near 10 knots. && .KEY WATCHES/WARNINGS/ADVISORIES...
