* WHAT...Minor saltwater flooding. * WHERE...Lower and Middle Florida Keys. * WHEN...Through late tonight. * IMPACTS...Minor saltwater flooding of low elevation streets and lots is likely.

Motorists should remember that persistent puddles around the times of high tide are almost certain to contain a mix of saltwater.
Do not drive through flooded roadways.
