The WPC Issued a Marginal Risk for Excessive Rainfall, level 1 of 4, for the Florida Keys. The marginal risk remains through 8 AM Saturday morning. Heavy rain may lead to flooding of low-lying areas, and storm drains may fill. King Tides and Coastal Flood Advisory exacerbate flooding issues from rainfall. The chance of heavy rain will decrease tomorrow morning and afternoon.

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.
