Coastal Flood Advisory
Ends in 14 h 59 min
When
Until 5 AM EDT Sunday, especially at the times of high tide.
Where
Middle and Lower Florida Keys.
Issued for this forecast zone · National Weather Service Key West FL
What, impacts and precautionsHide details
What
Saltwater flooding.
Impacts
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.
Precautionary actions
If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.
