SATELLITE ANALYSIS AND TRENDS...TS HUMBERTO CONTINUES ON A NNE HEADING
AND WAS LOCATED IN THE VIC OF 28.8N/94.7W OR ABOUT 35 MILES SSE OF GLS
ACCORDING TO LATEST IR SATELLITE IMAGERY.  0Z SURFACE ANALYSIS SHOWS
THAT BEST PRESSURE FALLS ARE LOCATED BETWEEN LCH AND ARA AND THIS WOULD
SUGGEST THAT A CONTINUED NNE TO EVEN NE HEADING SHOULD CONTINUE THROUGH
AT LEAST THE SHORT TERM.  OVER THE LAST HOUR OR SO HAVE BEGUN TO NOTICE
RAPIDLY COOLING CLOUD TOPS JUST WEST OF THE CENTER OF CIRCULATION WHICH
IS INDICATIVE OF RAPIDLY INCREASING RAINFALL RATES.  SATELLITE SUGGESTS
THAT THE MOST INTENSE RAINFALL RATES OF OVER 2.0"/HR ARE FALLING ABOUT
15-20 MILES SE OF GLS BUT IT IS STILL QUITE LIKELY THAT HEAVIER RAINFALL
RATES OF UP TO 1.0"/HR ARE AFFECTING PORTIONS OF GALVESTON ISLAND.
.
IT DOES APPEAR AS THOUGH A RATHER POTENT OUTER RAINFALL BAND HAS
ORGANIZED FROM SW JEFFERSON COUNTY AND EXTENDS TO THE SE TOWARDS THE VIC
OF 50 MILES SSW OF LCH AND THEN EXTENDS S ALONG 93.4W.  THE MOST RAPID
DECREASE IN CLOUD TOP TEMPS HAVE OCCURRED OVER THE PAST 30-60 MINUTES
NEAR 29.0N/93.3W.  THIS OUTER RAINFALL BAND WILL CONTINUE TO ROTATE
INTO PORTIONS OF EXTREME SE TX AND SW LA OVER THE NEXT SEVERAL HOURS
AND PROVIDE LOCALIZED HEAVY RAINFALL RATES OF 1-2"/HR.
.
MANUAL AND AUTOMATED SATELLITE ESTIMATES INDICATE THAT 4-7" OF RAIN
HAS FALLEN OVER THE PAST 6HRS FROM VERY NEAR JAMAICA BEACH TO ABOUT 25
MILES SE OF GLS.  WOULD EXPECT SIMILAR 6HR RAINFALL TOTALS TO CONTINUE
NNE OVER THE NEXT 3-6HRS AND AFFECT COASTAL LOCATIONS FROM GLS AND
EVENTUALLY PUSH INTO PORTIONS OF JEFFERSON COUNTY AND CAMERON PARISH.
WILL CONTINUE TO MONITOR.
