000 AXPZ20 KNHC 031539 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1529 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...SPECIAL FEATURES... Gulf of Tehuantepec Gale Warning: Strong high pressure persists across the Gulf of Mexico and extending southward across eastern Mexico today. This is forcing persistent northerly gales across the Gulf of Tehuantepec, with peak downstream seas currently near 12 ft. As the high weakens some, winds should fall just below gale force 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 along 86W N of 04N, moving west at 10 to 15 kt. Scattered moderate to strong convection is from 05N to 11N between 81W and 86W. A tropical wave is along 102W from 06N to 14N, moving west at 10 kt. This wave interacting with gap winds downstream of the Gulf of Tehuantepec, and is forcing scattered moderate to strong convection from 09N to 14N between 101W and 106W. A tropical wave extends along 112W from 04N to 17N, moving west at 10 kt. Scattered moderate to strong convection is from 07N to 15N between 107W and 117W. A tropical wave is located along 125W from 05N to 17N, moving west at 10 kt. No significant convection is associated with this wave. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N77W TO 10N94W TO 09N110W. The ITCZ extends from 08N113W TO 07N127W TO 09N140W. Convection along these axes is described above with the tropical waves, as well as from 09N to 12N between 88W and 93W, where scattered moderate convection is occurring. 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 will shift eastward today, and allow for winds to diminish across the Gulf today through 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 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, 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 around 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. 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. $$ KONARIK
