...FLOODING POTENTIAL CONTINUES ACROSS PORTIONS OF MIAMI-DADE...
THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

RATES RANGING FROM 2 TO 4 INCHES PER HOUR CONTINUE ACROSS PORTIONS
OF MIAMI-DADE FROM WESTWOOD LAKES TO VIRGINIA GARDENS. AS A
RESULT...A FLASH FLOOD WARNING HAS BEEN ISSUED THROUGH 330 AM FOR

ACROSS THE ADJACENT ATLANTIC WATERS. THE PRIMARY THREATS WILL BE
OCCASIONAL LIGHTNING STRIKES AND HEAVY RAINFALL.

CONCENTRATED.
THUNDERSTORMS WILL REMAIN POSSIBLE EACH DAY THROUGH THE REMAINDER
OF THE WEEK WITH LIGHTNING...GUSTY WINDS AND LOCALIZED HEAVY RAINS
BEING THE MAIN THREATS.

510 AM EDT MON MAY 20 2013
THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE FLORIDA KEYS AND ADJACENT
COASTAL WATERS.
.DAY ONE...TODAY AND TONIGHT
...THERE IS A SLIGHT CHANCE OF WATERSPOUTS THIS AFTERNOON ACROSS
FLORIDA BAY...THE WATERS INSIDE HAWK CHANNEL...AND THE IMMEDIATE
NEARSHORE GULF WATERS NORTH OF THE LOWER AND MIDDLE KEYS...
THE COMBINATION OF LOW LEVEL MOISTURE AND A FAVORABLE ALIGNMENT OF
NORTHEASTERLY WINDS OVER THE KEYS ISLAND CHAIN COULD ALLOW FOR CLOUD
LINES TO FORM NEAR THE ISLAND CHAIN THIS AFTERNOON. SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS WILL BE POSSIBLE WITHIN THESE
CLOUD LINES...AS WELL AS A SLIGHT CHANCE OF WATERSPOUTS. WATERSPOUTS
TEND TO FORM NEAR LARGE CLOUD BUILDUPS WITH DARK FLAT BASES.
WATERSPOUTS CAN EASILY OVERTURN SMALL VESSELS. IF YOU SIGHT A
WATERSPOUT...DETERMINE THE DIRECTION ITS MOVING AND MIGRATE IN THE
OPPOSITE DIRECTION.
.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY
ISOLATED THUNDERSTORMS WILL IMPACT THE FLORIDA KEYS...AS WELL AS
NEARSHORE AND OFFSHORE WATERS SURROUNDING THE ISLAND CHAIN. THE
PRIMARY THUNDERSTORM HAZARD WILL BE CLOUD TO SURFACE LIGHTNING
STRIKES AND LOCALLY GUSTY WINDS.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED.
