JUST INLAND FURTHER ENHANCING RAIN RATES.  MICROWAVE 15KM RESOLUTION
AREAL AVG RAIN RATE MAX HAD REACHED 1.4"/HR ON SSMI 2148Z/2219Z PASSES
AND 1.3"/HR ON AMSU 21Z PASS AND WHEN ADVECTED WEST FROM THOSE TIMES THE
CURRENT AREAL AVG MAX INSTANTANEOUS RAIN RATES WOULD BE SIMILAR ALONG AND
INLAND FROM THE N COAST.  THESE AREAS ARE AND WILL CONTINUE TO BE MOST
VULNERABLE FOR LOCALIZED FLOODING NEXT 3-4HRS.  GOES HYDROESTIMATES UP
TO 4" PER 6HRS OFFSHORE AND ISLAND PRECIP ESTIMATES NOT BEING HANDLED
