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.

Elevated Rain Chances through the end of the week. Thunderstorms possible with any shower. Well above normal rain chances through the end of the week as a stationary frontal boundary and a weak low pressure center interact with each other through late week. Light to gentle NE to E breezes becoming E to SE by Thursday night.
