SATELLITE ANALYSIS AND TRENDS...PER LATEST TROPICAL CYCLONE POSITION
ESTIMATE AND RECENT IR IMAGERY, THE EYE OF DOLLY WAS APPROXIMATELY
NEAR  25.9N/96.8W.  EYE CONTINUES TO BECOME BETTER ORGANIZED WITH
TIME AND RECENT IMAGERY SHOWS CONVECTION BEGINNING TO FILL IN OVER THE
WESTERN PORTION OF THE EYE WALL WHILE ALSO DEEPENING RAPIDLY OVER THE
N AND NE SEGMENTS OF THE EYE WALL.  OUTER RAIN BAND CURRENTLY ARCING
FROM 27.6N/96.5W AND EXTENDING THROUGH SE KENEDY COUNTY TOWARDS HRL HAS
BEEN MOVING ON A STEADY WESTWARD PACE AND WILL MOVE THROUGH REMAINING
PORTIONS OF CAMERON/WILACY/KENEDY COUNTIES WHILE ALSO MOVING ONSHORE
KLEBERG/NUECES COUNTIES OVER THE NEXT HOUR OR SO.  ALTHOUGH BAND IS
STEADILY MOVING, WOULD EXPECT A QUICK BURST OF LOCAL RAINFALL RATES
OF 1.0-2.0"/HR WITH THE MOST LIKELY AREAS TO SEE THESE RATES NEAR THE
BROKEN BAND OF OVERSHOOTING TOPS FROM CNTRL WILLACY COUNTY NE TOWARDS
PADRE ISLAND OFF OF KENEDY COUNTY.  HAVE ALSO  SEEN A SIGNIFICANT AMOUNT
OF CLOUD TOP COOLING EAST OF PIL, NEAR SOUTH PADRE ISLAND, AND EXTENDING
SOUTH TOWARDS THE MOUTH OF THE RIO GRANDE AND WOULD ALSO EXPECT RAINFALL
RATES OF AT LEAST 1.0"/HR WITH THIS AREA.
.
FURTHER UP THE COAST, NEARLY STATIONARY INFLOW BAND MAY BE INTERACTING
WITH INVERTED COASTAL TROF IN THE VIC OF MATAGORDA COUNTY.  IR AND EARLY
DAY VIS IMAGERY SHOWS THAT THE AREA BETWEEN COLLEGEPORT AND LAKE AUSTIN
HAS SEEN REDEVELOPING OVERSHOOTING TOPS AND WOULD ESTIMATE LOCAL RAINFALL
RATES OF 1.0-2.0"/HR HAVE BEEN AFFECTING THIS AREA OVER THE PAST HOUR.
ADDITIONAL OVERSHOOTING TOPS APPEAR TO BE DEVELOPING ABOUT 20 MILES SE OF
THE MATAGORDA PENINSULA AND SHOULD MOVE OVER THE AREA OVER THE NEXT 1-2
HRS AND THIS SHOULD CONTINUE THE HEAVY RAIN THREAT OVER THE LOCAL AREA.
.
AUTOMATED SATELLITE ESTIMATES SUGGEST THAT 4-6" OF RAIN HAS FELL OVER THE
OPEN GULF DURING THE LAST 6 HOURS IN THE SOUTHERN FLANK OF THE SYSTEM.
OVER THE LAST SEVERAL HOURS THE MOST ACTIVE CONVECTION HAS SHIFTED TO
THE NORTHERN FLANK OF THE SYSTEM AND BELIEVE THESE TYPES OF TOTALS ARE
POSSIBLE OVER THE NEXT 6 HRS ALONG AND JUST NORTH OF THE EYE  OF DOLLY.
LATEST ISALLOBARIC ANALYSIS SUGGESTS THIS COULD POSSIBLY BE JUST N OF
BRO PERHAPS IN THE VIC OF PIL.
