The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1400 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: Strong high pressure will continue building southward through far southern Mexico through Sun, which will allow gales to persist in the Gulf of Tehuantepec. Winds will then decrease to strong breezes through early next week. Seas of up to 13 ft can be expected in the Gulf today, before diminishing tonight and Sun to 9 to 11 ft, then below 8 ft by Mon. Please read the latest High Seas Forecast issued by the National Hurricane Center under AWIPS/WMO headers FZPN03 KNHC/HSFEP2 or at website https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for further details on the Gale Warning. ...TROPICAL WAVES... A tropical wave along 82W N of 03N into. Scattered moderate to strong convection is from 03N to 09N E of 84W. A tropical wave is along 98W from 06N to 14N, moving west at 10 kt. This wave interacting with northerly gales in the Gulf of Tehuantepec is leading to scattered moderate to isolated strong convection 09N to 13N between 95W and 102W. A tropical wave extends along 109W from 05N to 15N, moving west at 10 to 15 kt. Scattered moderate to isolated strong convection from 08N to 16N between 103W and 110W. A tropical wave is located along 120W from 05N to 15N, moving west at 10 kt. Little convection or shower activity is occurring with this wave. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N77W to 10N95W to 08N105W. The ITCZ extends from 09N110W to 07N130W to 10N140W. Scattered moderate convection is occurring from 06N to 14N west of 134W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of Tehuantepec: See the Special Features section for details on a Gale Warning. Gulf of California: Strong high pressure over the Great Basin well north of the region continues to support fresh NW to N winds through most of the Gulf of California, with seas 4 to 5 ft. The high pressure is weakening, thus conditions will continue to improve through this evening. For the remainder of the area, a weak pressure pattern is maintaining generally light breezes, and slight to moderate seas over open waters. Except for locally moderate NE winds near Baja California Sur, these conditions are expected to continue through early next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Weak only weak high pressure dominating the region, modest pressure gradient will keep winds in the gentle to moderate category with slight to moderate seas into early next week. Offshore winds around 15 kt prevail across the Papagayo region and will pulse to around 15 to 20 kt each of the next few nights. Farther south, gentle to moderate S- SW monsoonal flow, occasionally pulsing to moderate to fresh, will continue across the offshore forecast waters of Costa Rica, Panama, Colombia and Ecuador through the upcoming weekend. Seas will build west of 92W off Guatemala through tonight due to the northerly swell being generated from the gale force gap winds across the Gulf of Tehuantepec. REMAINDER OF THE AREA... High pressure north of the area will maintain a modest pressure gradient north of the tropics and produce gentle to moderate winds north of 20N, and moderate to locally fresh trade winds south of 20N for the next several days. Slight to moderate seas are expected across the regional waters as no significant swell events are expected through Mon. $$ KONARIK
