Northerly gale force winds behind the front are funneling across
the Chivela Pass, supporting storm-force winds in the Tehuantepec
region this afternoon. Storm-force winds will continue tonight
and diminish to strong gale-force Sun morning. Peak seas will 
range between 18 to 22 ft tonight. Gale-force winds will then continue
through Sun evening. Afterwards, strong to near gale-force winds
will gradually diminish through Mon morning. For further details,

between 90W to 98W, and from 02N to 07N between 118W and 131W. 

OFFSHORE WATERS WITHIN 250 NM OF MEXICO

Surface ridging anchored by a 1029 mb high near 30N130W continues
to provide moderate NE winds along the Baja California offshore 
waters with seas in the 3-5 ft range. Along the Gulf of California,
fresh to strong NW winds continues all the way to the Nayarit 
offshore waters with 5 to 6 ft seas. Light to gentle NW winds are
elsewhere along the SW Mexican offshore waters with seas to 3 
ft. 

A gap wind event is ongoing for the region of Tehuantepec with 
storm-force winds. See the Special Features section for further 
details. Fresh to strong winds in the Gulf of California will 
gradually diminish this evening. Otherwise, moderate to fresh 
winds will prevail off Baja California Norte through the middle 
of next week when the next gap wind event is forecast for 
Tehuantepec. 

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and 
WITHIN 750 NM OF ECUADOR

A weak pressure gradient across the area is supporting light to 
gentle variable winds with seas to 5 ft. Moderate E winds are 
pulsing in the Gulf of Papagayo and in the Gulf of Panama. 

Gentle winds will prevail through most of the forecast period, 
except for the Papagayo region where winds will pulse to fresh to
strong by Sun through the middle of the week. Moderate northerly
winds will also pulse in the Gulf of Panama tonight through Mon 
night. 

REMAINDER OF THE AREA

High pressure of 1029 mb high near 30N130W continues to extend a

winds and seas of 5 to 8 ft N of the ITCZ and W of 115W. Locally
strong winds are noted from 10N to 15N W of 137W.

Moderate to fresh NE to E winds will continue across the area
