A Coastal Flood Advisory is in effect for all Florida Keys!

Saltwater flooding of low elevation streets and lots is expected. 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. Little improvement is expected at low tide in the Upper Keys.

High Chance of Rain Today, Drying Out by Sunday...Coastal Flood Advisory for all Florida Keys. Rain chances peak near 90% today, then steadily decrease through the weekend. A Coastal Flood Advisory continues for all Florida Keys due to King Tides. Bouts of heavy rain occurring around high tide may exacerbate flooding issues. Marine breezes will be SE-S and light to gentle today, becoming SW and gentle to moderate tomorrow, then decreasing and veering to the NW by Sunday.
