Gulf of Tehuantepec Gale Warning: North to northeast gale-force winds in the Gulf of Tehuantepec will continue through early Mon with wave heights in the 8 to 10 ft range. Swell generated by these winds spreads well to the southwest of the Gulf of Tehuantepec region to near 10N100W. Near gale force winds are expected on Mon morning, diminishing to fresh to strong in the afternoon hours. Mariners should exercise caution if transiting in this region. Please read the latest HIGH SEAS FORECAST- https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from 08N78W to 06N90W to 04N101W. The ITCZ begins near 04N101W and continues along 03N130W to 03N140W. Scattered moderate isolated strong convection is from 04N to 08N between 80W and 92W, and from 02N to 05N between 97W and 104W. Scattered moderate convection is from 03N to 08N W of 122W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section above for details on gale-force winds in the Gulf of Tehuantepec region. The pressure gradient between a nearly stationary ridge west of Baja California and lower pressure over the SW CONUS will continue to support fresh to locally strong NW winds over the Baja California Norte offshore waters, with the strongest winds being within 120 nm off the coast mainly N of Punta Eugenia. These conditions are forecast to prevail through Fri while moderate to locally fresh NW winds are expected over Baja California Sur offshores. Seas over the Baja California adjacent waters will range between 5 to 7 ft, with the highest seas over the northern peninsula offshores. Gentle to locally moderate NW winds in the Gulf of California will become lighter on Mon before shifting to moderate SE winds on Tue and Wed. Elsewhere, light to gentle winds are expected to continue through Fri with seas to 6 ft in mixed southwest and northwest swell. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Strong east-northeast winds in the Gulf of Papagayo region will continue through Mon night with seas to 7 ft. Moderate to fresh winds will then continue to pulse through Wed. Moderate to fresh N to NE winds in and downstream of the Gulf of Panama will continue through Tue with seas to 6 ft. Light to gentle winds and 4 to 7 ft seas prevail elsewhere across the region. Large seas will continue west of Central America, from northern Costa Rica to Guatemala, from swell generated in the Tehuantepec and Papagayo source areas into Monday. REMAINDER OF THE AREA... The pressure gradient between a 1024 mb high near 33N126W and lower pressures in the tropics is supporting fresh northeast to east trade winds from 05N to 15N west of 115W. Wave heights within this area are around 8 ft in mixed north to northwest and southerly swell. In the far NW waters, a cold front extends from 30N134W TO 24N140W. Currently, fresh to strong west winds are behind the front with seas to 10 ft. The front is expected to stall and weaken over the far NW waters tonight. Seas are forecast to build to the 8-12 ft range today through Mon, with highest seas expected in the far NW part of the area. $$ Ramos
