000 AXPZ20 KNHC 032157 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Sun Nov 3 2019 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2115 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: Strong high pressure across the Gulf of Mexico continues to support northerly gale force winds across the Gulf of Tehuantepec with seas peaking to 14 ft. As the high weakens some, winds should fall just below gale force late tonight. Strong northerly gap winds are then expected to continue across Tehuantepec throughout the week, and will pulse at night to near 30 kt. 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 is along 85W N of 04N, moving west at 10 to 15 kt. Isolated moderate convection is from 04N to 10N E of 90W. A tropical wave is along 109W from 08N to 16N, moving west at 10 kt. Scattered moderate to isolated strong convection is from 08N to 17N between 102W and 118W. A tropical wave is located along 129W from 03N to 11N, moving west at 10 kt. No significant convection is associated with this wave. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 06N77W to 09N87W to 07N96W to 11N105W to 09N116W. The ITCZ extends from 09N118W to 06N129N to 06N136W to 08N140W. Scattered moderate convection is from 05N to 11N between 119W and 124W, and from 05N to 13N W of 135W. For further information on convection, see the Tropical Waves Section above. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of Tehuantepec: See the Special Features section for details on a Gale Warning. Gulf of California: High pressure over the Great Basin well north of the region is supporting moderate NW to N winds through most of the Gulf of California, with seas of 2-4 ft. The high pressure is weakening and shifting eastward this evening, which will allow for winds to diminish across the Gulf the next several days. For the remainder of the area, a weak high pressure ridge extending SE into the region is generally producing gentle to moderate winds across the regional waters, with slight to moderate seas of less than 6 ft in mainly NW swell over open waters. Except for locally moderate N to NE winds near Baja California Sur, these conditions are expected to continue through the entire week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Weak high pressure dominates the region, with a modest pressure gradient expected to keep gentle to moderate offshore winds N to 10N, and slight to moderate seas into early next week. Offshore winds around 15 kt prevail across the Papagayo region and will pulse to 20 kt 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. 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 tradewinds from 08N-24N W of 120W for the next several days. Slight to moderate seas are expected across the regional waters as no significant swell is expected through Tue. $$ Ramos
