Hurricane Isaias does not pose a threat to the Florida Keys outside of enhanced W swell for the SE Gulf waters and the W FL Straits. An upper-level disturbance currently over Cuba will continue moving NW today. This will be accompanied by abundant moisture. Therefore, expect increasing rain chances, peaking tonight. Gentle to moderate SE-S breezes expected through at least early Sunday before slackening over the second half of the holiday weekend and the holiday itself.

A Coastal Flood Statement remains in effect for all of the Florida Keys through late tonight. High tides will be around .75 feet above normal. Minor saltwater flooding of low elevation streets and lots is likely around the times of higher high tide. Some storm drains will overflow, and some seawalls and docks will be overtopped. Boaters should 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.
