Do not drive through flooded roadways.

* WHAT...Minor saltwater flooding. * WHERE...Upper and Middle Florida Keys. * WHEN...Through Friday afternoon. * IMPACTS...Minor saltwater flooding of low elevation streets and lots is likely. In the Middle Keys, this will be most pronounced around the time of the morning high tide. In the Upper Keys, little relief can be expected, even at lower tides. 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.
