RECENT SCATTEROMETER SATELLITE PASS INDICATES FRESH TO STRONG
WINDS WITHIN 90 NM ON THE E SEMICIRCLE OF INVEST EP97, THAT IS A
1008 MB LOW PRESSURE, LOCATED SOUTH OF CLARION ISLAND NEAR
17N114W. MODERATE TO LOCALLY ROUGH SEAS ACCOMPANY THESE WINDS.
SCATTEROMETER DATA ALSO SHOW MODERATE TO LOCALLY FRESH NW WINDS
OFF THE COAST OF SW MEXICO. SIMILAR WINDS SPEEDS ARE ALSO NOTED
OVER THE NORTHERN GULF OF CALIFORNIA. LIGHT TO GENTLE WINDS AND
MODERATE SEAS DOMINATE THE OFFSHORE FORECAST WATERS OF BAJA
CALIFORNIA.
FOR THE FORECAST, AWAY FROM THE IMPACTS OF T.S. NORBERT AND
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 1020 MB HIGH PRESSURE LOCATED
N OF AREA NEAR 34N133W 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 116W TO BAJA
CALIFORNIA PENINSULA.
