This Hazardous Weather Outlook is for the Florida Keys and
adjacent coastal waters.

.DAY ONE...TODAY AND TONIGHT

Isolated thunderstorms are possible along the Florida Keys and
the surrounding coastal waters today and tonight. The primary
thunderstorm hazards will be cloud to surface lightning strikes.

Otherwise observed water levels will lie near to just above
Coastal Flood Statement and Coastal Flood Advisory thresholds for
the Lower/Middle Keys and Upper Keys respectively. This will
result in minor saltwater flooding of low-lying lots and roads.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

Isolated to scattered thunderstorms are anticipated along the
Florida Keys and the surrounding coastal waters. The primary
thunderstorm hazards will be cloud to surface lightning strikes
and the potential for gusty winds, particularly Saturday through
Sunday. Flooding may also be a concern with any heavy shower or
thunderstorm this weekend (given how much rain has already fallen
over the past week and continued relatively high water levels).

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not anticipated.
