SATELLITE ANALYSIS AND TRENDS...FOR THE MOST PART, CLOUD TOPS HAVE
GENERALLY WARMED THROUGH THE MORNING WITH HUMBERTO WHICH COINCIDES WITH
A SLIGHT BIT OF A REDUCTION IN THE COVERAGE AND THE INTENSITY OF RAINS
DIRECTLY ASSOCIATED WITH THIS SYSTEM, ALTHOUGH SOME INCREASE IN CELLS ON
THE LEADING PERIPHERY HAS BEEN NOTED OVER CENT AND S MS/SW AL. SATELLITE
ESTIMATES FOR THE PAST 6 HOURS ARE STILL POINTING TOWARD 2 REGIONS
OF HIGHER TOTALS. ONE ASSOCIATED WITH THE NE QUADRANT OF THE CENTER OF
HUMBERTO HAS PRODUCED AUTOMATED SATELLITE ESTIMATED TOTALS BETWEEN 2-4"/6
HRS WITH ISOLATED TOTALS UP TO 5" OVER BEAUREGARD/VERNON/RAPIDES/GRANT
PARISHES OF W LA. THE SECOND MAX WITH THE PRIMARY INFLOW/CONVERGENCE
BANDS ALSO PRODUCED ESTIMATES OF 2-4"/6 HRS FROM AROUND E VERMILION
TO TERREBONNE/W LAFOURCHE PARISHES. THERE WERE HIGHER ESTIMATED
TOTALS ASSOCIATED WITH THIS BAND BUT THEY WERE OFFSHORE AS TRENDS FOR
TRAINING/BACK BUILDING NOTED IN EARLIER SPENES MESSAGE AT THIS POINT HAVE
NOT LED TO HIGHER INLAND TOTALS AS RELATIVE DRY SLOT WRAPPING AROUND S
PORTION OF HUMBERTO HAS CONSISTENTLY PUSHED THE INLAND PORTION OF THE
BAND EASTWARD DURING THE MORNING. AS A RESULT THE PIVOT POINT ALONG THE
BAND FOR CELL TRAINING AND HIGHER TOTALS HAS REMAINED AND CONTINUES
TO REMAIN OFFSHORE. WILL CONTINUE TO MONITOR THE SITUATION TO SEE IF
ANYTHING CHANGES, BUT AT THIS TIME THE INLAND FEATURE ALONG THE S AND
SE COASTAL REGION CONTINUES TO BE PROGRESSIVE. FARTHER TO THE NE ACROSS
S CENT MS AND SW AL CELLS ALONG THE LEADING EDGE HAVE BEEN MOVING ALONG
AND AT THIS POINT ARE LIKELY MORE BENEFICIAL THAN ANYTHING ELSE. HOWEVER,
WITH CENTER OF HUMBERTO STILL WELL TO THE WEST BACK OVER W CENT LA MOVING
RATHER SLOWLY THERE IS SOME THREAT OF RAINS EVENTUALLY EXCEEDING APPARENT
FFG VALUES ESPECIALLY IF SOMETHING FLARES UP NEAR THE CENTER LATER THIS
EVENING/OVERNIGHT.
