SCATTEROMETER DATA SHOWED GENTLE TO LOCALLY MODERATE SOUTHERLY
WINDS THROUGH THE FULL LENGTH OF THE GULF OF CALIFORNIA, WITH A
FEW AREAS OF MODERATE SW GAP WINDS, AND MODERATE TO FRESH W TO SW
WINDS WRAPPING AROUND THE SOUTHERN END OF THE PENINSULA. SLIGHT

WINDS ARE GENTLE TO MODERATE. SEAS OF 5 TO 7 FT IN FADING NW
SWELL GENERALLY PREVAIL ACROSS THE WATERS NORTH OF THE

OF THE MEXICO WATERS AND IS SUPPORTING GENTLE TO LOCALLY
MODERATE WINDS EASTWARD TO CHIAPAS. SEAS ACROSS THESE WATERS ARE
4 TO 6 FT IN MIXED NW AND S SWELL. SCATTERED MODERATE TO STRONG
THUNDERSTORMS HAVE BEGUN TO MOVE SOUTHWESTWARD OVER THE COASTAL

THUNDERSTORMS. FRESH NE TO E GAP WINDS PERSIST ACROSS THE
PAPAGAYO REGION AND EXTEND OFFSHORE TO 90W, AND ARE FEEDING INTO

WATERS. ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR GRADUAL
DEVELOPMENT OF THIS LOW PRESSURE SYSTEM, AND A TROPICAL
DEPRESSION IS LIKELY TO FORM BY LATE THIS WEEK OR OVER THE
