SOUTHEAST FLORIDA

CONCERNS FOR LOCALLY VERY HEAVY RAINFALL WILL CONTINUE INTO THIS
AFTERNOON ACROSS COASTAL SOUTHEAST FLORIDA.  SLOW MOVING CELLS IN
A REGION OF STRONG BOUNDARY LAYER CONVERGENCE IN THE EASTERLY
ONSHORE FLOW IN THE VICINITY OF THE NORTHWARD MOVING FRONTAL ZONE
OVER SOUTHEAST FL WILL CONTINUE TO SUPPORT POTENTIAL FOR ISOLATED
RAINFALL AMOUNTS OF 3-5"+ IN A FEW HOURS FROM THE MIA METRO AREA
NORTHWARD TO JUST NORTH OF PBI.  THE RAP32 IS SHOWING BOUNDARY
LAYER CONVERGENCE WEAKENING BY LATE AFTERNOON WHICH MAY SIGNAL
LESSENING OF THE HEAVY RAINFALL THREAT.  CONFIDENCE NOT GREAT WITH
HOW LONG THE HEAVY RAIN THREAT WILL CONTINUE---BUT OVER THE NEXT
FEW HOURS---THE POTENTIAL FOR VERY HEAVY TOTALS WILL POSE RUNOFF
PROBLEMS---ESPECIALLY IN URBANIZED AREAS.
