FRESH TO STRONG SW WINDS AND ROUGH SEAS ON THE SOUTHERN SIDE OF
THE REMNANTS OF RACHEL ARE IMPACTING THE NORTHERN GULF OF
CALIFORNIA. WIND FLOW AROUND THE SYSTEM IS ALSO FORCING MODERATE
TO LOCALLY FRESH GAP WINDS OVER PORTIONS OF THE CENTRAL GULF OF
CALIFORNIA. IN ADDITION, A COLD FRONT IS MOVING ACROSS THE NE
WATERS. ROUGH SEAS GENERATED BY STRONG NORTHERLY WINDS OFFSHORE
CALIFORNIA, AND BEHIND THE COLD FRONT, CONTINUE TO PROPAGATE
ACROSS THE WATERS WEST OF THE BAJA CALIFORNIA PENINSULA. MODERATE
TO FRESH N WINDS ARE BLOWING ACROSS THE TEHUANTEPEC AREA WITH
SEAS OF 5 TO 7 FT. ELSEWHERE, OUTSIDE OF THE AREAS IMPACTED BY
HURRICANE SIMON, MODERATE OR WEAKER WINDS AND SLIGHT TO MODERATE
SEAS PREVAIL.

LINGERING WEST OF THE BAJA CALIFORNIA PENINSULA WILL GRADUALLY
DIMINISH THROUGH EARLY THIS WEEK. ELSEWHERE, DISORGANIZED
