Tropical Storm ANDRES
ZCZC MIATCDEP1 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM ANDRES DISCUSSION NUMBER 19
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 AM PDT SAT MAY 24 2003
ANDRES CONTINUES TO MAINTAIN DEEP CONVECTION...WITH TOPS COLDER THAN
-80C...NEAR A HARD-TO-FIND CENTER OF CIRCULATION. HOWEVER...
WESTERLY OR SOUTHWESTERLY SHEAR IS CONFINING THE CONVECTION TO THE
EASTERN SEMICIRCLE OF THE CYCLONE. THE LATEST DVORAK
CLASSIFICATIONS FROM TAFB...SAB...AND AFWA AGREE ON 35 KT...AND
THAT REMAINS THE OFFICIAL INTENSITY ESTIMATE FOR THIS ADVISORY.
THE PAST FEW QUIKSCAT PASSES HAVE MISSED ANDRES...BUT THE
UPCOMING ONE SHOULD BE A HIT AND MIGHT SHED SOME ADDITIONAL LIGHT ON
THE INTENSITY.
ANDRES IS CROSSING THE 26C SST ISOTHERM...AND FOR THE NEXT COUPLE OF
DAYS WILL BE PASSING UNDER STRONG SOUTHWESTERLY FLOW IN ADVANCE OF
AN UPPER-LEVEL TROUGH EAST OF THE HAWAIIAN ISLANDS. THE CURRENT
STRONG CONVECTIVE BURST MAY THEREFORE BE THE LAST SIGNIFICANT
ONE...AND ANDRES IS EXPECTED TO GRADUALLY SPIN DOWN OVER THE NEXT
FEW DAYS. THE OFFICIAL FORECAST GENEROUSLY CARRIES A CIRCULATION
FOR 96 HOURS. HOWEVER...GIVEN THE FORWARD SPEED OF THE CYCLONE...
CURRENTLY 15 KT...THE CIRCULATION COULD EASILY OPEN UP INTO A WAVE
BEFORE THEN.
THE INITIAL MOTION IS 285/15. AS THE CONVECTION DIMINISHES OVER
COOLER WATERS...ANDRES SHOULD BEGIN TO MOVE WITH THE LOW-LEVEL
FLOW. THE OFFICIAL FORECAST SHOWS A SLIGHT TURN TO THE WEST AFTER
12 HOURS AND FOLLOWS THE SPEED OF THE SHALLOW LAYER BAM MODEL. THE
OFFICIAL FORECAST IS A LITTLE FASTER THAN THE PREVIOUS ADVISORY
TRACK.
