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 into the weekend. -Drier air will filter in over the weekend, and offer the first taste of the Fall season for the Florida Keys. && .DISCUSSION... Issued at 1030 PM EDT Wed Oct 8 2025 A strong surface high is spreading southward across the eastern United States. This along with weak troughing near and south of the Keys, along with considerable moisture is contributing to scattered to numerous showers across the forecast area this evening. With that said, thunderstorm activity has been rather rare. Winds have come up a slightly due to a moderately tighter pressure gradient between the previously mentioned features. Expect continued high rain chances through the overnight due to the presence of the trough and high moisture values. At least likely rain chances remain justified. Away from convection, expect gentle to moderate northeast to easterly breezes. Overnight lows will be in the upper 70s with dew points in the mid 70s. The combination of periodic doses of rain in concert with King tide will continue to be problematic for areas prone to flooding. A Coastal Flood Advisory remains in effect for all Florida Keys. Motorists should assume that any standing water is at least brackish and likely ocean water. && .MARINE...
