FOR THE FORECAST, AWAY FROM THE IMPACTS OF INVEST EP97, A RIDGE
WILL BUILD ACROSS THE OFFSHORE WATERS OF BAJA CALIFORNIA,
BRINGING MODERATE TO LOCALLY FRESH NW TO N WINDS SUN INTO EARLY
NEXT WEEK. EXPECT FRESH WINDS ACROSS THE NORTHERN GULF OF
CALIFORNIA EARLY NEXT WEEK DUE TO THE PRESSURE GRADIENT BETWEEN
THE RIDGE AND LOWER PRESSURE OVER THE COLORADO RIVER VALLEY.
LOOKING AHEAD, FRESH TO STRONG N TO NE GAP WINDS WILL PULSE AGAIN
IN THE TEHUANTEPEC REGION BY THE MIDDLE OF NEXT WEEK, BUILDING
SEAS TO 8 OR 9 FT.

AWAY FROM THE IMPACTS OF T.S. NORBERT, MODERATE TO LOCALLY FRESH
SE WINDS AND ROUGH SEAS ARE FOUND SOUTH OF 04N AND WEST OF THE
GALAPAGOS ISLANDS TO ABOUT 135W. A 1019 MB HIGH PRESSURE LOCATED
N OF AREA NEAR 32N131W DOMINATES THE WATERS NORTH OF 20N. UNDER
THE INFLUENCE OF THIS SYSTEM, AND AWAY FROM NORBERT, MAINLY
MODERATE WINDS AND MODERATE SEAS PREVAIL, WITH THE EXCEPTION OF
LIGHT TO GENTLE WINDS NORTH OF 20N AND EAST OF 115W TO BAJA
CALIFORNIA PENINSULA.
