Gulf of Tehuantepec Gale Warning: Fresh to near gale force N to NE gap winds in the Gulf of Tehuantepec will pulse through Mon night, except for gale-force northerly winds forecast to commence shortly through Sun morning, then return briefly Sun night. Seas will become rough to very rough during the period of gale-force winds, peaking around 15 ft by early Sun. Please read the latest HIGH SEAS FORECAST issued by the National Hurricane Center at website - https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08.5N78.5W to 03.5N95W. The ITCZ extends from 03.5N95W to 02N114W to 04N124W to beyond 06.5N140W. Scattered moderate isolated strong convection is noted from 03N to 06N between 84W and 94W, and from 06N to 09N between 138W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see SPECIAL FEATURES above for more on a Gulf of Tehuantepec gale-force gap wind event. Fresh to near gale-force N winds prevail in the Gulf of Tehuantepec, along with 5-7 ft seas. Moderate to locally fresh winds are noted near Punta Eugenia and also near Cabo San Lucas. Elsewhere, light to gentle winds, and slight to moderate seas are noted, except locally rough seas well offshore Baja California Norte. For the forecast aside from the Gulf of Tehuantepec, moderate to locally fresh SE-S winds will pulse in the Gulf of California Sun into Sun night. Elsewhere, light to gentle winds through Wed night, pulsing to moderate to fresh near Baja California Norte, near Cabo San Lucas, and near Cabo Corrientes at times. Slight to moderate seas will prevail over the waters away from the Gulf of Tehuantepec. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE-E winds prevail over the Papagayo region. In the Gulf of Panama, moderate N-NE winds are noted. Elsewhere, light to gentle winds prevail. Slight to moderate seas dominate the waters. For the forecast, in the Gulf of Papagayo, fresh to strong NE winds will pulse through early Wed reaching downwind to 92W, with moderate to locally rough seas. Moderate to fresh winds will pulse in the Gulf of Panama with moderate seas through Tue night. Rough seas will build well offshore western Guatemala by early Sun through Sun night due to a developing Gulf of Tehuantepec gale-force gap wind event. Gentle breezes and slight to moderate seas will prevail elsewhere through the forecast period. Looking ahead, large SW swell will build rough seas from Ecuador offshore to the Galapagos Islands by mid-week. ...REMAINDER OF THE AREA... A complex gale-force low pressure system is NW of the area. Outer associated moderate to locally fresh SE-S winds and rough seas are near the NW waters close to 30N140W. Rough seas in northerly swell are N of 27N between 119W and 129W. Gentle to moderate winds and moderate seas are found over the remainder of the discussion waters as confirmed by recent ASCAT scatterometer data and altimeter passes. For the forecast, associated rough swells over the far NW and N-central waters due to the complex low pressure system NW of the area will linger through early today before subsiding. Rough seas from a developing gale-force gap wind event in the Gulf of Tehuantepec will spread SW and impact the waters roughly N of 07N and E of 106W Sun through Mon. Fresh to strong winds will pulse across these waters as well extending downwind from the Tehuantepec event. Elsewhere, gentle to moderate winds will prevail over the open waters. Moderate seas will prevail otherwise into early Sun across the open waters. Rough seas in southerly swell may impact the waters S of the Equator mid-week.
