EVENT...TRAP FOR IVAN SAYS 3-6 INCHES CAN FALL SW LA/TX BORDER AREA...
.
CURRENT SATELLITE ANALYSIS AND TRENDS...LATEST TRMM PASS AT 0740Z HAD A 1.75"
INSTANTANEOUS RAIN RATE JUST SOUTH OF S CENTRAL LA COAST NEAR CENTER OF IVAN.
THIS RELATES WELL WITH SUPER COLD TOP (-76C) CELL THAT HAS BEEN DRIFTING W/NW
WITH CENTER OF IVAN WITH MODERATE RAIN RATES FALLING COASTAL S CENTRAL LA. 
NOT EXPECTING MUCH PROBLEMS IN SHORT TERM AS IVAN CONTINUES WNW...BUT LATEST 
OPERATION NESDIS TROPICAL RAINFALL POTENTIAL (TraP) SAYS YOU CAN EXPECT 3-6
INCHES IN A 24HR PERIOD ACROSS SW LA INTO EXT E TX IF IVAN HOLD TOGETHER.

SLIGHT CHANCE DRY AIR AROUND THE WEST SIDE OF STORM COULD TEMPER THESE AMOUNTS
BUT FEEL CONFIDENCE THAT PW VALUES OF 2.3" SEEN FROM MICROWAVE DATA ALONG THE
EAST SIDE OF IVAN WILL QUICKLY MOISTEN UP AREAS THAT IVAN/S CENTER APPROACHES.
