A Coastal Flood Advisory is in effect for the Upper Keys! A Coastal Flood Statement is now in effect for the Middle and Lower 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.
