The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0305 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: Building ridge over NE Mexico supports fresh to strong northerly winds and rough seas across the Gulf of Tehuantepec. Winds will further increase to gale force overnight tonight into early Mon, with seas building to 12 to 14 ft on Mon night into early Tue. Gusty winds to near storm force may occur. These marine conditions are forecast to persist through early Tue morning. Seas generated from this gap wind event will spread well away from the Tehuantepec area, with seas 8 ft or greater reaching as far south as 11N Mon night into Tue. Please read the latest High Seas Forecast issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N78W to 05N99W. The ITCZ stretches from 05N99W to 07N120W to beyond 05N140W. A second ITCZ is located south of the Equator and runs from 06S85W to 02S127W. Scattered moderate convection is observed along surface trough. Numerous moderate convection is evident south of 10N and west of 115W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please refer to the Special Features section for details on a developing Gulf of Tehuantepec Gale Warning. A strengthening ridge over the southern United States is forcing fresh to strong northerly winds and seas to 8 ft in the Gulf of Tehuantepec. Meanwhile, a weak ridge centered west of Baja California supports moderate or weaker winds and moderate seas across the offshore waters of the aforementioned peninsula. Moderate or weaker winds and slight to moderate seas are found in the Gulf of California waters. Elsewhere, light to gentle winds and moderate seas in southerly swell prevail in the remaining Mexican offshore waters. For the forecast, other than the developing Gale Warning in the Gulf of Tehuantepec, gentle to moderate winds and slight seas will prevail in the Gulf of California through much of the week, pulsing to moderate to fresh in the central portion early week. Moderate to locally fresh NW winds and moderate seas are expected off Baja California through the forecast period. However, winds may increase to strong N of Punta Eugenia Thu night through Fri night. Looking ahead, fresh to strong N winds may return to the Gulf of Tehuantepec by early Fri. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... The subtropical ridge centered north of the basin supports mainly moderate easterly trade winds across the Gulf of Papagayo region, along with seas of 4-5 ft. Farther east, moderate N-NE winds and moderate seas are present in the Gulf of Panama. Meanwhile, light to gentle winds and moderate seas dominate the remainder of the offshore forecast waters. Some active convection is present offshore Colombia and Panama as described above. For the forecast, fresh to strong gap winds are expected during the nighttime and early morning hours in the Papagayo region and downwind to about 90W through the forecast period. Moderate to locally fresh northerly winds are forecast in the Gulf of Panama through much of the week. A gap wind event in the Tehuantepec region will produce seas to 8 ft in the far offshore waters of Guatemala Mon night through Tue. Light to gentle winds and moderate seas will prevail elsewhere. ...REMAINDER OF THE AREA... A cold front is approaching the far NW waters of the tropical eastern Pacific. A few showers are noted ahead of this boundary. Farther south, a deep upper level trough continues to produce abundant cloudiness and some showers over the western waters, especially N of 14N and W of 120W. At the surface, a weak high pressure system over the northern waters dominates the remainder of the tropical eastern Pacific. Moderate to locally fresh easterly winds are occurring north of the ITCZ and west of 110W. Seas in these waters remain around 6 to 8 ft. Elsewhere, moderate or lighter winds and moderate seas are prevalent. For the forecast, a cold front is forecast to reach 30N140W tonight, and extend from 30N137W to 24N140W by Mon morning. Gentle to moderate winds are forecast on either side of the front. Seas will briefly build to 9 ft behind the front Mon night into Tue. High pressure will support moderate to locally fresh easterly winds and moderate to locally rough seas across the trade wind zone into the middle of the week, supporting seas to around 8 ft. Seas may build to around 8 ft in southerly swell near 03.4S by the end of the week. $$ Delgado ########################### END OF MESSAGE SET ############################
