The combination of the current King Tide cycle and persistent bouts of rainfall will support additional flooding over roadways and low lying lots. Coastal flooding will likely continue through the holiday weekend. -First taste of Fall returns to the Keys in the wake of today`s frontal passage. Drier air filtering in behind will promote rapidly decreasing rain chances into next week. && .AVIATION... (18Z TAFS) Issued at 318 PM EDT Sat Oct 11 2025 Shower coverage will completely diminished into the evening and winds will steadily become more northwest to north in the wake of the recent frontal passage. Any additional MVFR CIGs will be temporary as drier air slowly filters in across the terminals overnight. && .MARINE... Issued at 1047 AM EDT Sat Oct 11 2025 From synopsis, an elongated area of low pressure across the Keys will continue slowly drifting northeastward today. This will support one more day of well above normal rain chances along with south to southwesterly light to gentle breezes gradually backing to the northwest to north tonight and Sunday. This low will continue organizing and strengthening as it heads northeastward adjacent to the Mid- Atlantic coast. As it does this, it will drive an early season cold front towards the Keys, further shifting winds to the north to northeast. Northerly swells will be possible in our western marine zones today and tonight due to the influence of the low pressure system. In the wake of the front, high pressure builds across the eastern United States leading to freshening northeasterly breezes heading towards mid- week. && .KEY WATCHES/WARNINGS/ADVISORIES...
