Coastal Flood Statement issued September 18 at 10:01AM EDT until September 19 at 6:00AM EDT by NWS Key West FL

Effective: Thu September 18, 2025, 10:01 AM
Expires: Thu September 18, 2025, 6:00 PM

* WHAT...Minor saltwater flooding. * WHERE...Upper Florida Keys. * WHEN...Through late tonight. * IMPACTS...Minor saltwater flooding of low elevation streets and lots is likely. Some storm drains will overflow, and some seawalls and docks will be overtopped. Boaters can expect less clearance under fixed bridges. Motorists should remember that persistent puddles around the times of high tide are almost certain to contain a mix of saltwater.

Do not drive through flooded roadways.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
