SATELLITE ANALYSIS AND TRENDS...IR IMAGERY ANIMATION INDICATES NO LET-UP
IN MOD TO HVY SHOWER ACTIVITY AFFECTING LOS ANGELES AS WELL AS ORANGE
COUNTY. WHILE THE CORE OF THE VERY WARM TOP BAND..WHICH EXTENDS WELL
SW OF THE COAST..HAS SHIFTED EWD FM EARLIER IN THE EVENING.. INDIVIDUAL
CELLS HAVE CONTINUED TO MOVE NEWD AND TRAIN OVER PARTS OF THE DISCUSSION

ANGELES/ORANGE COUNTY BORDER AREA. OTHER COOLING TOPS ARE OFFSHORE INVOF
CATALINA ISLAND. WHEREAS MUCH OF THE ACTIVITY DURING THE EVENING HAS
BEEN FOCUSED OVER LOS ANGELES COUNTY..LATEST TRENDS INDICATE THAT WHILE
LOS ANGELES COUNTY WILL CONTINUE TO HAVE MOD/HVY SHOWERS OVER THE NEXT
FEW HRS..ORANGE COUNTY WILL BE FACED WITH CELL TRAINING AS WELL. WOULD
EXPECT THE COOLER TOP SHOWERS NOW INVOF CATALINA ISLAND WILL AFFECT
ORANGE COUNTY..WHICH IS ALREADY BEING AFFECTED BY MOD/HVY CELLS. ALSO
NOTICING SOME COOLING TOPS OVER VENTURA COUNTY..SO SOME MOD/HVY SHOWERS
ARE LIKELY TO PERSIST THERE OVER THE NEXT COUPLE OF HRS.

EXTENDING FM S OF CATALINA ISLAND ACRS THE AREA FM VENTURA THRU ORANGE
COUNTIES..WITH THE CORE OF THE CONVERGENCE OVER CATALINA/SAN CLEMENTE
ISLANDS THRU S LOS ANGELES/ORANGE COUNTIES. ADDITIONALLY..GOES STLT
WIND PLOTS SHOW SRLY WINDS 20-30KTS BTWN 700-900MB SW OF THE COAST. THE
COMBINATION OF THIS BROAD LL JET AND SFC CONVERGENCE HAS BEEN HELPING
TO GENERATE/RE-GENERATE THE MOD/HVY SHOWERS AFFECTING THE REGION. DUE
TO THE RESOLUTION LIMITATION OF MICROWAVE DATA..SSMI AND AMSU HAVE BEEN
UNDERDOING THE EXTENT AND INTENSITY OF THE RAINFALL. EXTREME WARM TOP
NATURE OF THE EVENT HAS ALSO PRECLUDED GOES-BASED QUANTITATIVE RAINFALL
ESTIMATES.
