INFORMATION IS BASED ON SATELLITE IMAGERY, WEATHER OBSERVATIONS,
RADAR, AND METEOROLOGICAL ANALYSIS.
BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0855 UTC.
..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH
THE MONSOON TROUGH EXTENDS FROM COSTA RICA NEAR 09N84W AND
CONTINUES WESTWARD TO 07N110W. THE ITCZ STRETCHES FROM 07N110W
TO 06N125W AND BEYOND 06N140W. SCATTERED MODERATE TO ISOLATED

SIMILAR CONVECTION IS EVIDENT FROM 04N TO 10N AND WEST OF 133W.
..OFFSHORE WATERS WITHIN 250 NM OF MEXICO
AN EXPANSIVE 1029 MB HIGH PRESSURE SYSTEM CENTERED NORTH OF
HAWAII EXTENDS WEAKLY TO THE REVILLAGIGEDO ISLANDS. A RECENT
SCATTEROMETER SATELLITE PASS CAPTURED GENTLE TO MODERATE NW WINDS
OVER MUCH OF THE OFFSHORE WATERS OF BAJA CALIFORNIA. FRESH NW
WINDS ARE NOTED SOUTH OF PUNTA EUGENIA. MODERATE SEAS ARE PREVALENT
ACROSS THESE WATERS. MODERATE TO LOCALLY FRESH SW WINDS AND
SLIGHT TO MODERATE SEAS ARE NOTED IN THE GULF OF CALIFORNIA.
LATEST SATELLITE-DERIVED WIND DATA ALSO SHOWED FRESH TO LOCALLY
STRONG NW WINDS OFF THE COAST OF JALISCO. SEAS IN THESE WATERS
ARE MODERATE. IN THE REMAINDER OF THE MEXICAN OFFSHORE WATERS,
INCLUDING THE GULF OF TEHUANTEPEC, MODERATE OR WEAKER WINDS AND
MODERATE SEAS PREVAIL.
FOR THE FORECAST, MODERATE TO LOCALLY FRESH NW WINDS WILL
CONTINUE ACROSS THE BAJA WATERS TODAY THROUGH SAT MORNING, AHEAD
OF AN APPROACHING COLD FRONT. THE COLD FRONT WILL MOVE INTO THE
BAJA NORTE WATERS SAT EVENING AND REACH THE CENTRAL BAJA WATERS
SUN, ACCOMPANIED BY A SIGNIFICANT INCREASE IN WINDS AND SEAS
ACROSS THE BAJA OFFSHORE WATERS, AND STRONG TO NEAR GALE-FORCE
WESTERLY GAP WINDS ACROSS THE GULF OF CALIFORNIA THROUGH MON

...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
THE MONSOON TROUGH CONTINUES TO GENERATE SHOWERS AND ISOLATED
THUNDERSTORMS ACROSS THE NEARSHORE AND OFFSHORE WATERS OF COSTA
RICA, PANAMA AND COLOMBIA. A RECENT SCATTEROMETER SATELLITE PASS
INDICATE THAT STRONG TO NEAR GALE-FORCE SOUTHERLY WINDS ARE FOUND
IN THE AREAS WITH THE STRONGEST CONVECTION. MARINERS SHOULD USE
CAUTION NAVIGATING THESE WATERS. WEAK HIGH PRESSURE NORTH OF THE
AREA SUPPORTS GENTLE TO LOCALLY MODERATE WINDS AND SLIGHT TO
MODERATE SEAS ACROSS THE GULFS OF PAPAGAYO AND PANAMA. MAINLY
MODERATE SOUTHERLY WINDS AND SEAS OF 4-6 FT ARE FOUND SOUTH OF
05N.
FOR THE FORECAST, MODERATE WINDS ARE EXPECTED TODAY IN THE
PAPAGAYO REGION BEFORE DIMINISH DURING THE WEEKEND. GENTLE

A STRONG COLD FRONT IS APPROACHING THE FAR NORTHWEST WATERS,
WHILE A BROAD SUBTROPICAL RIDGE POSITIONED NORTH OF HAWAII
DOMINATES THE REMAINDER OF THE TROPICAL EASTERN PACIFIC. THE
PRESSURE GRADIENT BETWEEN THE AFOREMENTIONED RIDGE AND THE ITCZ
SUSTAIN MODERATE TO LOCALLY FRESH EASTERLY WINDS FROM THE ITCZ TO
20N AND WEST OF 110W. THIS WAS CONFIRMED BY A RECENT
SCATTEROMETER SATELLITE PASS, WHICH ALSO SUGGESTED THAT STRONG
WINDS ARE OCCURRING IN THE WESTERN WATERS IN ASSOCIATION WITH THE
CONVECTION IN THE AREA. SEAS IN THESE WATERS ARE 6-9 FT.
ELSEWHERE, MODERATE OR WEAKER WINDS AND MODERATE SEAS PREVAIL.
FOR THE FORECAST, THE AFOREMENTIONED COLD FRONT WILL ENTER THE
NW WATERS THIS AFTERNOON AND REACH FROM SOUTHERN CALIFORNIA TO
30N122W TO 26N140W SAT EVENING, AND FROM CENTRAL BAJA CALIFORNIA
TO 23N140W BY SUN EVENING. STRONG HIGH PRESSURE BUILDING BEHIND
