LOCALLY ROUGH SEAS ARE IN THE GULF OF TEHUANTEPEC. A WEAK RIDGE
DOMINATES THE OFFSHORE FORECAST WATERS OF BAJA CALIFORNIA
PRODUCING LIGHT TO GENTLE WINDS WITH MODERATE SEAS. LIGHT TO
GENTLE WINDS ARE ALSO NOTED IN THE GULF OF CALIFORNIA WITH SLIGHT
SEAS. ACTIVE CONVECTION IS PRESENT IN THE VICINITY OF CABO
