CENTER WILL SHIFT INTO THE AREA TODAY. THIS WILL MAINTAIN THE 
FRESH TO STRONG TRADES OVER THIS AREA. AS THE HIGH PRESSURE 
CENTER SHIFTS INTO THE AREA TODAY...THE PRESSURE GRADIENT 
BETWEEN THIS AREA OF HIGH PRESSURE AND TROUGHING OVER WESTERN 
MEXICO WILL TIGHTEN. THIS WILL STRENGTHEN WINDS OFF THE WESTERN

MAINTAIN NEAR 20 TO 25 KT OVER THE NEXT COUPLE OF DAYS. WINDS 
WILL PEAK NEAR GALE FORCE LATE TONIGHT WITH THE ADDED COMPONENT 
OF NOCTURNAL DRAINAGE FLOW.

GULF OF PANAMA...THE STRONG TRADEWIND FLOW OVER THE CARIBBEAN 
WATERS IS FUNNELING INTO THE GULF OF PANAMA. WINDS IN THE 20-25
