S-SW light to gentle breezes this morning become W-NW and light by this evening, then NW-N by Sunday. A Coastal Flood Advisory continues to be in effect for all Florida Keys!

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.
