DIVERGENT FLOW ALOFT NORTH OF AN UPPER LOW IS SUPPORTING A LINE
OF SHOWERS AND THUNDERSTORMS FROM 15N105W TO ACROSS THE MEXICAN
COAST OF SINALOA. FRESH N GAP WINDS ARE ACROSS THE GULF OF
TEHUANTEPEC. ELSEWHERE, GENTLE TO MODERATE BREEZES AND 3-5 FT
SEAS PREVAIL ACROSS MEXICAN OFFSHORE WATERS, WITH 1-3 FT SEAS IN
THE GULF OF CALIFORNIA.
FOR THE FORECAST, A RIDGE WILL BUILD ACROSS THE OFFSHORE WATERS
OF BAJA CALIFORNIA, BRINGING MODERATE TO LOCALLY FRESH NW TO N
WINDS THROUGH THE EARLY PART OF THE WEEK. EXPECT FRESH WINDS
ACROSS THE NORTHERN GULF OF CALIFORNIA THROUGH THE EARLY PART OF
THE WEEK DUE TO THE PRESSURE GRADIENT BETWEEN THE RIDGE AND LOWER
PRESSURE OVER THE COLORADO RIVER VALLEY, LOCALLY STRONG TONIGHT.
WINDS WILL FRESHEN AGAIN OFF BAJA CALIFORNIA BY THE END OF THE
WEEK, LOCALLY STRONG NEAR PUNTA EUGENIA. LOOKING AHEAD, EXPECT
STRONG TO NEAR- GALE N GAP WINDS AND ROUGH SEAS ACROSS THE
TEHUANTEPEC BY THE MIDDLE OF THE WEEK.
