GULF OF TEHUANTEPEC GALE WARNING: THE PRESSURE GRADIENT BETWEEN
HIGH PRESSURE NORTH OF THE AREA AND THE EASTERN NORTH PACIFIC
MONSOON TROUGH WILL SUPPORT FRESH TO NEAR GALE-FORCE NORTHERLY
GAP WINDS AND MODERATE TO ROUGH SEAS IN THE GULF OF TEHUANTEPEC
THROUGH THE END OF THE WEEK. WINDS IN TEHUANTEPEC WILL PULSE TO
GALE-FORCE TONIGHT AND WED NIGHT. SEAS WILL PEAK AROUND 11 FT
(3.5 M) WITH THE STRONGEST WINDS. CONDITIONS WILL IMPROVE BY THE
WEEKEND.
PLEASE READ THE SPECIAL FEATURES SECTION FOR MORE DETAILS ON A
GALE WARNING IN THE GULF OF TEHUANTEPEC.
OUTSIDE OF THE GULF OF TEHUANTEPEC, AN EASTWARD-MOVING COLD
FRONT IS LOCATED SEVERAL HUNDRED MILES WEST OF GUADALUPE ISLAND.
MODERATE TO FRESH SOUTHERLY WINDS AND MODERATE SEAS ARE NOTED
IN THE OFFSHORE WATERS OF BAJA CALIFORNIA NORTE, ESPECIALLY WEST
OF GUADALUPE ISLAND. A WEAK PRESSURE GRADIENT DOMINATES THE
REMAINDER OF THE BASIN, RESULTING IN LIGHT TO GENTLE WINDS AND
SLIGHT TO MODERATE SEAS OVER MUCH OF THE MEXICAN OFFSHORE WATERS.
FOR THE FORECAST, ASIDE FROM THE GULF OF TEHUANTEPEC, A COLD
FRONT WILL APPROACH THE OFFSHORE WATERS OF BAJA CALIFORNIA NORTE,
SUPPORTING FRESH TO STRONG SOUTHERLY WINDS TONIGHT INTO WED.
NORTHWEST SWELL WILL PROPAGATE INTO THE WATERS NORTH OF PUNTA
EUGENIA TONIGHT INTO WED. A REINFORCING SWELL WILL SPREAD ROUGH
SEAS ACROSS THE OFFSHORE WATERS OF THE BAJA CALIFORNIA PENINSULA
THE END OF THE WEEK INTO THE WEEKEND. FRESH TO LOCALLY STRONG
SOUTHERLY WINDS WILL DEVELOP IN THE NORTHERN GULF OF CALIFORNIA
WED NIGHT INTO THU. MODERATE TO FRESH NW WINDS ARE EXPECTED IN
THE CENTRAL AND SOUTHERN GULF OF CALIFORNIA THU NIGHT INTO THE
WEEKEND.

ELSEWHERE, A SURFACE TROUGH IN THE TRADE WATERS ALONG 113W IS
PRODUCING A FEW SHOWERS AND THUNDERSTORMS. FRESH TO STRONG
EASTERLY WINDS AND SEAS OF 6-8 FT ARE ALSO PRESENT EAST OF THIS
BOUNDARY. FARTHER EAST, MODERATE TO FRESH EASTERLY WINDS AND
SEAS OF 6-8 FT ARE OCCURRING NORTH OF 10N AND EAST OF 102W DUE TO
THE GAP WIND EVENT IN THE GULF OF TEHUANTEPEC. IN THE REMAINDER
OF THE AREA, WINDS ARE MODERATE OR WEAKER ALONG WITH MODERATE
SEAS.
