HURRICANE RINA WHICH IS DRAWING TROPICAL MOISTURE OVER THE SE
GULF TO ACROSS FLORIDA AND THE STRAITS OF FLORIDA WITH SCATTERED
SHOWERS/ISOLATED THUNDERSTORMS S OF 25 E OF 90W. A SURFACE RIDGE
AXIS DOMINATES THE N GULF ANCHORED BY A 1020 MB HIGH IN THE W
ATLC AND WITH VERY DRY STABLE AIR ALOFT IS GIVING THE REMAINDER
OF THE GULF CLEAR SKIES AGAIN TONIGHT. THE SURFACE RIDGE WILL
REMAIN OVERNIGHT THEN WILL WEAKEN THU IN ADVANCE OF A COLD FRONT
THAT MOVES OFF THE TEXAS COAST LATE THU AFTERNOON/EARLY EVENING
QUICKLY REACHING FROM THE FLORIDA BIG BEND TO THE E BAY OF

COVERING THE CARIBBEAN BETWEEN 67W-82W WITH A WEAKENING SURFACE
TROUGH EXTENDING FROM SW HAITI NEAR 18N74W TO 12N75W. TOTAL
PRECIPITABLE WATER IMAGERY INDICATES A BROAD AREA OF DEEP
MOISTURE COVERS THE CARIBBEAN BASIN W OF 65W AND COUPLED WITH
THE CONVERGENCE OF SURFACE FLOW AND THE FLOW ALOFT ARE
GENERATING SCATTERED SHOWERS/ISOLATED THUNDERSTORMS FROM 9N-21N
W OF THE SURFACE TROUGH TO 83W. THE MONSOON TROUGH HAS BEEN
RE-ESTABLISHED ACROSS THE SW CARIBBEAN FROM COLOMBIA NEAR 10N75W
ALONG 11N75W TO ACROSS COSTA RICA/NICARAGUA INTO THE E PACIFIC
