EVENT...HVY RAINS ASSCD WITH T.S. HERMINE
.
SATELLITE ANALYSIS AND TRENDS...CENTER OF T.S. HERMINE CAN BE SEEN VERY
CLEARLY IN RADAR IMAGERY OVER THE KLEBERG/JIM WELLS COUNTY BORDER AND
RECENTLY HAS STARTED TO TAKE ON A SLIGHTLY MORE NWRLY TRACK THAN THE NR
DUE N TRACK IT HAS BEEN ON MOST OF THE NIGHT. RICH MOISTURE CONTINUES
TO BE PUMPED NWWD FROM THE WRN GOM AND INTO THE SE TX COAST/S CENTRAL
REGION OF TX. AS HERMINE BEGINS TO TAKE ON MORE OF A NWRLY MOVEMENT PER
THE NHC FCST TRACK..THIS SHOULD ALLOW FOR ADDTL PRECIP TO LIFT NW TWDS
CENTRAL TX. NUMEROUS OVERSHOOTING TOPS HAVE BEEN NOTICEABLE IN THE VERY
COLD CNVTN OF THE OUTER BAND OF THIS STORM DURING THE LAST 2-3 HRS WITH
A FEW OCCASIONS WHERE CLOUD TOP TEMPS BREACHED THE -80C BARRIER.
.
GIVEN THE CENTER IS BEGINNING TO MOVE INLAND IT HAS APPEARED RECENTLY
THAT THE OUTER BAND HAS BEEN THE MAIN PRECIP PRODUCER..PROVIDING
COVERAGE OF MOD-HVY RAINFALL OVER A WIDE AREA OF THE TX COAST. ANOTHER
SMALL BAND IS BEGINNING TO SET UP THOUGH..JUST WITHIN THE LAST HR OR
SO..STRETCHING SSEWD FROM REFUGIO COUNTY. TORRENTIAL RAINFALL RATES
OF 2-3"/HR ARE LIKELY TO BE OCCURRING BENEATH THIS INNER BAND WHILE IN
GNRL ESTIMATED RATES OF 1-2"/HR ARE OCCURRING IN THE OUTER BAND(S) AS
CELLS COME ONSHORE. RATES ARE LIKELY LESSER INLAND BUT THE STRONG INFLOW
BEING WRAPPED INTO THE STATE WITH VWP'S INDICATING 30-40KTS OF 85H FLOW
WILL KEEP PUSHING MOISTURE/PRECIP FURTHER INLAND THROUGHOUT THE EARLY
MORNING. 6 HR SATL ESTIMATES ENDING 11Z HAVE GIVEN MAX AMOUNTS OF 5.2"
JUST OFF THE COAST OF REFUGIO COUNTY WITH A NR 5" ESTIMATE OVER PART OF
CAMERON COUNTY AND 4.5" OF SE CALHOUN COUNTY.

.
SHORT TERM OUTLOOK VALID 1130-1430Z..HIGH CONFIDENCE IN SHORT TERM
OUTLOOK..SLIGHT SHIFT IN TRACK NOW OF THE CENTER APPEARS TO BE GOING A
BIT MORE NW NOW PULLING RICH MOISTURE INTO CENTRAL TX WITH IT. HIGHEST
CHC FOR HVY RAINFALL THREAT IN SHORT TERM REMAINS NR THE COAST THOUGH
WHERE HVY RAINS HAVE ALREADY OCCURRED AND RATES WILL BE HIGHEST.
