LONG-PERIOD NW SWELL IS MOVING THROUGH THE OFFSHORE WATERS OF
BAJA CALIFORNIA NORTH OF CABO SAN LAZARO. AN ALTIMETER SATELLITE
DATA PASS FROM 02Z LAST NIGHT INDICATES SEAS OF 8 TO 10 FT OVER
THESE WATERS, WITH THE HIGHEST OF THE SEAS NORTH OF PUNTA
EUGENIA. SEAS OF 6 TO 8 FT IN NW SWELL ARE OVER THE OFFSHORE WATERS
FROM CABO SAN LUCAS TO CABO SAN LAZARO. ELSEWHERE, A RATHER WEAK
PRESSURE GRADIENT ACROSS THE REGION IS GENERALLY ALLOWING FOR
MODERATE OR LIGHTER NORTHWEST TO NORTH WINDS AND MODERATE SEAS,
EXCEPT FOR SLIGHT SEAS IN THE GULF OF CALIFORNIA AS NOTED IN
OVERNIGHT ALTIMETER SATELLITE DATA PASSES.
FOR THE FORECAST, THE LONG-PERIOD NW SWELL WILL GRADUALLY
SUBSIDE THROUGH TUE. A SECOND SET OF LARGE NW SWELL IS FORECAST TO
ENTER THE WATERS N OF PUNTA EUGENIA LATE THU, AND SPREAD THROUGH THE
REMAINDER OFFSHORE WATERS OF BAJA CALIFORNIA THROUGH FRI NIGHT.
FOR THE FORECAST, HIGH PRESSURE WILL CONTINUE TO BE THE MAIN
FEATURE OVER THE WATERS WEST OF ABOUT 115W THROUGH MIDWEEK.
THE NW SWELL WILL GRADUALLY SUBSIDE THROUGH TUE. A COLD FRONT IS
EXPECTED TO APPROACH 30N140W ON TUE NIGHT, PRECEDED BY FRESH TO
STRONG SOUTHWEST WINDS AND ROUGH SEAS. OTHERWISE, A BROAD AREA OF
LOW PRESSURE LOCATED SEVERAL HUNDRED MILES SOUTHWEST OF THE BAJA
CALIFORNIA PENINSULA IS PRODUCING LIMITED SHOWER AND
THUNDERSTORM ACTIVITY AS DESCRIBED ABOVE IN THE ITCZ/MONSOON
TROUGH SECTION. THE SYSTEM IS MOVING WESTWARD INTO AN
UNFAVORABLE ENVIRONMENT, AND DEVELOPMENT IS NO LONGER EXPECTED.
