1030 MB HIGH NEAR 35N45W TO 32N70W TO 30N95W. AN UPPER LEVEL LOW 
CENTERED NEAR 23N95W CONTINUES TO PROGRESS SLOWLY WESTWARD IN 
THE GULF OF MEXICO. DIFFLUENT FLOW ALOFT PRIMARILY EAST OF THE 
UPPER LOW IS ENHANCING CONVECTION OVER THE GULF OF MEXICO IN THE 
FORM OF SHOWERS. A WEAK TROPICAL WAVE IN THE EASTERN GULF IS  
PRODUCING SCATTERED SHOWERS AND ISOLATED TSTMS N OF HAVANA. A 
TROPICAL WAVE NEAR 64W IS PRODUCING SCATTERED SHOWERS AND

OFF THE E COAST OF THE U.S. WILL CAUSE THE RIDGE TO WEAKEN OVER
