.NOW...

Through 500 pm, a cluster of showers with isolated thunderstorms 

associated with conglomerating cloud streamers will continue to 

develop along and north of the Lower and Middle Keys. This activity 

will drift to the north at near 5 knots. Mariners encountering the 

strongest activity north of the Content Keys as well as just north of

Key West to Big Pine Key can expect moderate to heavy downpours 

reducing visibility and a few cloud to surface lightning strikes. A 

few island communities in the Lower Keys can except up to one quarter

of an inch of rainfall. Waterspouts also cannot be ruled out. 

Mariners are reminded that a waterspout would most likely appear 

beneath a dark, flat bottom of a building cumulus line, just at the 

hint of rain.
