Tropical Weather Discussion

CARIBBEAN SEA...
AN UPPER RIDGE AXIS EXTENDS ALONG THE N PORTION OF SOUTH AMERICA
GIVING THE SW CARIBBEAN SW FLOW ALOFT. THE UPPER RIDGE OVER THE
GULF OF MEXICO DIPS OVER THE NW CARIBBEAN GIVING THE AREA NW
FLOW ALOFT WHILE THE REMAINDER OF THE AREA IS UNDER NEAR ZONAL
WESTERLY FLOW ALOFT. THE MONSOON TROUGH EXTENDS FROM COLOMBIA
NEAR 10N75W THROUGH A 1009 MB LOW NEAR 11N80W TO ACROSS COSTA
RICA NEAR 11N83W ARE GENERATING SCATTERED SHOWERS AND POSSIBLE
ISOLATED THUNDERSTORMS S OF 12N BETWEEN W OF 80W AND WITHIN 60
NM ALONG THE COAST OF COLOMBIA. CLUSTERS OF SCATTERED SHOWERS/
ISOLATED THUNDERSTORMS CONTINUE OVER THE N/CENTRAL CARIBBEAN N
OF 18N BETWEEN 75W-80W. THE E CARIBBEAN IS COVERED IN THE
TROPICAL WAVE SECTION ABOVE. W ATLC SURFACE RIDGE WILL MAINTAIN
MODERATE TO FRESH SE TRADE WINDS WITH THE STRONGEST WINDS IN THE
GULF OF HONDURAS THROUGH SUN.

HISPANIOLA...
AN UPPER RIDGE BEGINS JUST N OF THE ISLAND EXTENDING NW OVER THE
W ATLC. TOTAL PRECIPITABLE WATER IMAGERY INDICATES MOISTURE IN
PLACE ACROSS THE ISLAND SO SOME ISOLATED SHOWERS ARE POSSIBLE
OVER THE INTERIOR SECTIONS OF THE ISLAND. THE UPPER RIDGE N OF
THE ISLAND IS MOVING E AS THE TROPICAL WAVE CONTINUES TO TRACK
W. THIS COULD BRING RAIN AND POSSIBLE THUNDERSTORMS TO
HISPANIOLA OVER THE NEXT DAY OR SO.
