Gulf of Tehuantepec Gale Warning: Strong high pressure will continue building southward over southern Mexico. Gales will persist in the Gulf of Tehuantepec, with seas to 14 ft through Sun night. Winds will then decrease to strong breezes through early next week. Seas will diminish to 9 to 11 ft, then below 8 ft by Tue. 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 83W N of 03N, moving west at 10 kt. Scattered moderate convection is from 03N to 09N E of 86W. A tropical wave is along 100W from 05N to 15N, moving west at 10 kt. This wave interacting with northerly gales in the Gulf of Tehuantepec has scattered moderate convection from 08N to 14N between 93W and 104W. A tropical wave extends along 111W from 03N to 17N, moving west at 10 to 15 kt. Scattered moderate convection is from 07N to 18N between 104W and 114W. A tropical wave is located along 123W from 04N to 17N, moving west at 10 kt. Isolated moderate convection is within 90 nm of the wave axis. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N78W to 10N95W to 09N110W. The ITCZ extends from 08N113W to 07N123W. The ITCZ resumes W of a tropical wave from 06N127W to 10N140W. Scattered moderate convection is from 05N to 11N between 135W and 139W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of Tehuantepec: See the Special Features section for details on a Gale Warning. Gulf of Papagayo: Moderate offshore gap winds will pulse to strong breeze across the Gulf of Papagayo region each night through early next week. 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 to 3 ft. The high pressure is weakening, thus conditions will continue to improve Sun. 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 high pressure dominates 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 20 to 25 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 moderate to fresh breeze from 18N-22N W of 130W for the next several days. Slight to moderate seas are expected across the regional waters as no significant swell events are expected through Mon. $$ Formosa
