THE AREA NEAR 37N130W EXTENDS NORTHWEST OF THE REVILLAGIGEDO
ISLANDS. THIS RIDGE DOMINATES THE OFFSHORE FORECAST WATERS OF
BAJA CALIFORNIA, AND SUPPORTS MODERATE TO LOCALLY FRESH NW WINDS
PER LATEST SATELLITE DERIVED WINDS NORTH OF CABO SAN LAZARO.
SEAS OF 6 TO 8 FT IN NW SWELL CONTINUE ACROSS THE WATERS N OF
CABO SAN LAZARO, WITH THE HIGHEST SEAS ACROSS THE FAR OUTER
