Gulf of Tehuantepec gale warning: Gale-force N to NE winds continue in the Tehuantepec region as a tight gradient remains in place over southern Mexico. Peak wave heights with these winds are in the 8-11 ft range. The wind fetch and swell associated with this event extends as far as 102W and 08N. Winds over the Tehuantepec offshore waters will diminish below gale-force speeds tonight and to strong speeds on Mon. Wave heights will continue to subside through Mon. A second gap wind event is forecast to begin Tue night with near gale-force N to NE winds continuing through Wed as high pressure builds southward over eastern Mexico.

A surface trough extends from northwestern Colombia near 07N78W to 0N91W to 05N111W to 05N118W, where it transitions to the ITCZ and continues to 04N130W to 04N140W. Scattered moderate convection is from 02S to 03N between 91W and 103W, and from 02N to 09N W of 117W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Surface ridging anchored by a 1027 mb high near 30N129W is maintaining moderate to fresh N to NE winds along the Baja California offshore waters, with wave heights of 3-5 ft due to a a NW swell. Along the Gulf of California, gentle to moderate NW winds are observed with wave heights to 3 ft. Light to gentle variable winds are elsewhere along the SW Mexican offshore waters, with wave heights of 3-4 ft. A gap wind event is ongoing for the region of Tehuantepec with gale-force winds to 40 kt. See the Special Features section for further details. Moderate to fresh N to NE winds will prevail off Baja California through Thu as the ridge continues to move eastward the next couple of days. A second NW swell event will affect the Baja offshore waters with seas of 8-10 ft Tue through Thu. Otherwise, the next gap wind event for the Tehuantepec region is forecast to begin Tue. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR Fresh to strong north to east winds are in the Gulf of Papagayo with seas to 6 ft while moderate north winds are in the Gulf of Panama with seas to 3 ft. Light to gentle variable winds are elsewhere with seas of 3-5 ft. Gentle winds continue will through most of the forecast period, except for the Papagayo region where the fresh to strong winds will continue 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 1027 mb high near 30N129W continues to extend a ridge across the area, with the related gradient supporting moderate to fresh northeast to east winds and wave heights 6-8 ft north of the ITCZ to 20N and west of 117W. Locally strong winds are likely in this region. These conditions are expected to continue through at least late on Tue as the gradient there tightens. Wave heights with these winds should range from 8-11 ft. Sporadic clusters of moderate convection are noted north of the ITCZ west of about 118W. $$ Ramos
