The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0350 UTC. ...SPECIAL FEATURES.... Gulf of Tehuantepec Gale Warning: Northerly winds behind a stationary front in the Gulf of Mexico are funneling through the Chivela Pass and supporting minimal gale-force NNE winds in the Gulf of Tehuantepec region. Gales will continue through early Tue morning when seas are expected to build to 13 ft. Gales will briefly resume again Tue evening and then again Wed night as strong high pressure builds over Texas just N of a surface trough over the western Gulf of Mexico. Seas in the Tehuantepec region during this period will range between 8-13 ft, building to 15 ft by Thu morning. Winds will diminish below gale-force Thu night, to fresh to strong speeds Fri morning and gentle to moderate speeds during the afternoon hours. Please refer to the latest NWS High Seas Forecast issued by the National Hurricane Center at the website: https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml, for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N81W to 07N93W to 09N104W to 06N111W. The ITCZ continues from 06N111W to 06N130W to beyond 06N140W. Scattered moderate convection is from 00N to 12N E of 92W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please, refer to the Special Features section above for details on an ongoing Gale Warning for the Gulf of Tehuantepec. A weak pressure gradient in the region due to a surface trough along western Mexico and another westward moving trough to the west of the Baja Califniania Peninsula continue to support light to gentle winds and moderate seas to 6 ft in NW swell along the Baja and SW Mexico offshore waters. High pressure over the Great Basin of the United States, is supporting moderate to fresh NW winds along the Gulf of California where seas are 3-6 ft. Otherwise, gales are ongoing in the Gulf of Tehuantepec where moderate seas are forecast to become rough tonight. For the forecast, minimal gale-force NNE winds ongoing in the Gulf of Tehuantepec region will continue through early Tue morning when seas are expected to build to 13 ft. Gales will briefly resume again Tue evening and then again Wed night as strong high pressure builds over Texas just N of a surface trough over the western Gulf of Mexico. Winds will diminish below gale- force Thu night, to fresh to strong speeds Fri morning and gentle to moderate speeds during the afternoon hours. Winds in the Gulf of California are forecast to reach locally strong speeds Tue and Tue night, gradually diminish to gentle to moderate speeds Wed night, and then prevail mainly over the southern and entrance of the Gulf through Sat night. Gentle to moderate NE winds are forecast to develop across the Baja California Sur Peninsula on Wed morning and prevail while expaning to the Baja Norte offshores through the weekend. Light to gentle winds are expected elsewhere. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh to strong NE to E winds and moderate seas to 6 ft are ongoing in the Gulf of Papagayo. Moderate E winds associated with this gap wind event extend to the outer offshore waters of Guatemala and El Salvador where seas are 6 ft in southerly swell. In the Gulf of Panama, winds are moderate to fresh from the NNE and seas are 3-5 ft. Light to gentle winds and slight to moderate seas in mixed SW and NW swell are elsewhere. For the forecast, fresh to strong NE to E winds in the Gulf of Papagayo will continue through Sat, likely increasing to near gale-force on Wed as high pressure ridging builds over the Caribbean. Rough seas to 10 ft are expected with this gap wind event. Moderate to fresh easterly winds from the Papagayo gap wind event will continue to propagate across the outer offshore waters of Guatemala and El Salvador through Wed night. Pulsing fresh N winds in the Gulf of Panama will diminish to moderate speeds on Thu and to light to gentle speeds over the weekend. Otherwise, light to gentle southerly winds between Ecuador and The Galapagos Islands will reach moderate speeds Sat night. ...REMAINDER OF THE AREA... A strong high pressure of 1035 mb located well N of area extends a ridge across the forecast waters N of the ITCZ and W of 110W. To the west of the Baja California offshore waters, a surface trough extends along 121W. The pressure gradient between the trough and the ridge to the west continues to support moderate to fresh NE to E winds N of 20N and W of 125W where seas are 8 to 11 ft in northerly swell. Elsewhere, winds are gentle to moderate and seas are moderate. For the forecast, a ridge will remain in control of the weather pattern across the waters N of the monsoon trough and ITCZ axis and W of 110W producing moderate to fresh trade winds. Northerly swell will continue to affect the subtropical waters with seas to 11 ft through at least mid-week. A surface trough will intensify W of Baja California Norte tonight while moving westward through Wed. The pressure gradient between the trough and high pressure to the N will support fresh to strong winds on either side of the trough axis on Tue. $$ Ramos
