EVENT...APPROACH OF HURRICANE DOLLY
.
SATELLITE ANALYSIS AND TRENDS...RECENT VIS/RADAR LOOPS SHOW THE
APPROACHING BANDS OF THE TIGHTLY WRAPPED CIRCULATION OF HURRICANE
DOLLY..CENTERED APPROX 255 KM ESE OF BRO. IN ADDTN CNVTN WILL SOON BE
PUSHING ONSHORE ALL ALONG THE TX COAST IN WHAT APPEARS TO BE A FORMER
OUTER BAND OF THE STORM. SOME RECENT ENHANCEMENT HAS OCCURRED WITH
THIS LOOSELY ORGANAIZED BAND OFFSHORE OF KPSX/KCRP AS WELL AS ONSHORE
TO THE W/NW OF THESE AREAS THOUGH IT APPEARS CNVTN HAS HAD A VERY HARD
TIME PROGRESSING INLAND DUE TO SURPRISINGLY DRY AIR IN CENTRAL TX/SW
TX. ALONG THE COAST GOES SOUNDER SHOWS PW'S 1.8-2.0" DECREASING INLAND
TO ONLY 1-1.2". OFFSHORE IS A MUCH DIFFERENT STORY AS DEEP MOISTURE IS
RATHER PLENTIFUL WITH AMSU PASS SHOWING 2-2.2" PW'S OFF THE TX COAST
AND 2.4" VALUES WITHIN DOLLY. AREAL AVG AMSU RAINFALL RATES WITHIN
THE STORM WERE UP TO 1.3"/HR DURING THE INSTRUMENT PASS. JUST IN NASA
TRMM PASS SHOWED SIGNIFICANTLY LOWER AREAL AVG RATES..MAX 0.75"/HR BUT
CONSIDERING THE DEEP TROPICAL MOISTURE ASSCD WITH THE STORM ALONG WITH
GOES STLT ESTIMATES..BELIEVE TRMM RATES ARE UNDERDONE.
.
WV SHOWS AN UPPER VORT OVER W TX THAT IS SLOWLY LIFTING NWD AS IT GETS
SQUEEZED BETWEEN DOLLY AND THE ANTICYCLONE OVER THE SW. UPPER HIGH
HAS NOWHERE TO GO BECAUSE OF THE JET ACROSS CA AT THIS TIME AND SO THE
LIFTING VORT OVER W CENTRAL TX SHOULD ALLOW FOR DOLLY TO CONTINUE ITS
NWWD MOVEMENT TWDS BRO. IR SHOWS COLDEST CLOUD TOPS ARE CURRENTLY ON
THE S SIDE OF THE CENTER AT -82C THOUGH VIS SHOWS SOME OVERSHOOTING
TOPS IN REDVLPG BAND ON THE N SIDE OF THE EYE THAT WILL WRAP AROUND
OVER TIME. 3HR AUTOMATED STLT ESTIMATES INDICATED AN AREA OF OVER 4"
AMOUNTS ON THE NWRN SIDE OF THE STORM..APPROX 130 MI ESE OF BRO. SEE
