.
EVENT...TORRENTIAL RAIN ALONG THE UPPER TEXAS GULF COAST AND THE DEEP
SOUTH TEXAS COAST
.
SATELLITE ANALYSIS AND TRENDS...SEVERAL FACTORS HAVE COME TOGETHER
TO SUPPORT HEAVY RAINFALL OVER THE UPPER TX CST. LOW LEVEL CYCLONIC
CIRCULATION S OF KGLS HAS ENHANCED SFC MOISTURE CONVERGENCE DUE TO FNTL
BNDRY AND LAND BREEZE. THIS HAS RESULTED IN VERY HEAVY RAIN ALG THE
COAST FROM BRAZORIA COUNTY UP TO THE LA STATE BORDER. CLD TOP TEMPS HAVE
REACHED -71C SUPPORTING ESTD HLF HRLY RAINFALL UP TO 1.5". GOES AND GPS
DERIVED PW/S INDICATE VALUES OF 2.0-2.3" ALG AND OFF THE COAST.
.
WITH PERSISTENT SE ONSHORE FLOW AND SLOW MVMNT TO CIRC CENTER MAIN
AREA OF CONCERN THROUGH THE MORNING HRS FOR VERY HEAVY RAIN WILL BE
CHAMBERS..JEFFERSON AND GALVESTON COUNTIES. 3 HR TOTS OF 3-4" PSBL.
.
LN OF CNVTN EXTENDS SW OF CIRC CENTER INTO WILLACY AND CAMERON
COUNTIES. VERY CD CLD TOPS SUPPORTING SIMILAR RAINFALL AMNTS IN SHORT
TERM – UP TO 1.5" PER HLF HR. HOWEVER..THERE DOES NOT APR TO BE A
SIMILAR FEATURE...LIKE THE CIRC CENTER FURTHER N...TO KEEP THE CNVTN
FOCUSED ON THIS AREA FOR A PROLONGED PD. THEREFORE DON'T EXPECT AS HEAVY
AMNTS OVER 3-4 HR PD FOR DEEP S TX.
