The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0830 UTC. ...SPECIAL FEATURES... Tropical Storm Ramon is centered near 14.4N 123.4W at 26/0900 UTC, moving west at 4 kt. Estimated minimum central pressure is 1005 mb. Maximum sustained wind speed is 35 kt with gusts to 45 kt. Peak seas are near 12 ft within 30 nm in the northern semicircle of center. There is no deep convection near the center of the system. Ramon is forecast to degenerate into a remnant low later today, and dissipate within 48 hours. After a southwestward jog overnight, the system is forecast to move on a more westward motion this morning followed by a westward to west- northwestward motion for the next day or so until dissipation occurs.

Gulf of Tehuantepec Gale Warning...high pressure building across the eastern slopes of Mexico will help tighten the pressure gradient across the Tehuantepec area early this week, with gale conditions expected Mon night through Tue night. Seas will peak near 12 ft with this upcoming event. 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... The monsoon trough extends from 10N85W to 09N98W to 10N119W. The ITCZ extends from 10N126W to 08N140W. Scattered moderate convection is noted from 04N to 12N between 89W and 110W, and from 08N to 12N between 128W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see above for more on an upcoming Gulf of Tehuantepec gale- force gap wind event. Gentle to moderate winds prevail over the northern Gulf of California, and off the coast of southern and SW Mexico. Light to gentle winds are noted elsewhere. Seas are in the 8-10 ft range off Baja California Norte, 6-8 ft off Baja California Sur, and 4-5 ft over the remainder of the open waters off Mexico. Over the Gulf of California, seas are in the 2-3 ft range, except reaching 4 ft in the northern Gulf. For the forecast, NW swell over the far offshore waters off Baja California Norte will reach the Revillagigedo Islands by late today. High pressure building across the eastern slopes of Mexico will help tighten the pressure gradient across the Tehuantepec area early this week, supporting strong to near- gale force winds over these waters through the middle of the week. Winds will reach gale- force Mon night through Tue night. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh gap winds are over and downwind of the Gulf of Papagayo. Light winds are elsewhere north of the monsoon trough. Gentle to moderate winds are noted between Colombia and the Galapagos Islands, with light to gentle winds elsewhere S of the monsoon trough. Seas of 4-5 ft prevail. For the forecast, moderate to fresh winds will pulse at night across and well downstream of the Gulf of Papagayo region through the period, reaching strong speeds early this week. Light to gentle winds are expected S of the monsoon trough, increasing to moderate speeds between Colombia and the Galapagos Islands early this week. ...REMAINDER OF THE AREA... Please see above for more information on Tropical Storm Ramon. Gentle to moderate winds persist outside of Ramon. NW swell continues to spread across the waters, with seas 8 ft or greater now roughly NW of a line from Baja California Norte to near 00N138W. Seas with the swell are peaking near 12 ft N of 28N and W of 128W. Combined seas are 5-7 ft elsewhere in mixed swell. For the forecast, the NW swell will continue to propagate southeastward, with seas greater than 8 ft covering much of the waters west of 120W into early this week. Winds and seas associated with Ramon are expected to cover a relatively small and localized area, with seas mixing with longer period NW swell. $$ AL
