000 AXPZ20 KNHC 041507 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1446 UTC Mon Nov 4 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 1400 UTC. ...TROPICAL WAVES... A tropical wave is along 93W from 04N to 12N, moving west at 10 kt. Scattered moderate convection is occurring just ahead of the wave from 06N TO 11N between 93W AND 100W. A tropical wave is along 115W from 06N to 16N, moving west at 10 kt. Numerous moderate and scattered strong convection is noted from 08N to 16N between 105W and 125W. A tropical wave is located along 134W from 04N to 12N, moving west at 10 to 15 kt. Scattered moderate convection is occurring from 07N to 11N between 126W and 135W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N77W to 09N88W to 07N98W to 12N108W to 09N120W. The ITCZ extends from 09N121W to 07N129N to beyond 07N140W. Scattered moderate convection is seen from 06N to 11N between 77W and 85W. Elsewhere, significant convection is described above in the Tropical Waves section. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of Tehuantepec: A broad high pressure ridge across the Gulf of Mexico is supporting strong winds across the Gulf of Tehuantepec today and peak seas near 12 ft. The high will weaken slightly across southeastern Mexico over the next couple of days, which will keep winds below gale force, around 30 kt. Strong northerly gap winds are expected to continue across Tehuantepec through the end of the week, and will pulse each night to near 30 kt. Gulf of California: Weak pressure gradient over the region is supporting variable light to gentle winds across most of the Gulf of California, with seas of 1-2 ft, except to 3 ft across the mouth of the Gulf. A strong ridge will build over the Great Basin well north of the area by the end of the week, and winds will increase moderate to fresh across the Gulf. 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 to 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... Strong high pressure will move N of the Caribbean waters during the week and will support pulses of fresh to strong winds at night in and downstream of the Gulf of Papagayo region. Seas are expected to build up to 8 ft during the peak winds. 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 centered north of the area will maintain a modest pressure gradient north of the tropics and produce moderate to fresh tradewinds W of 115W through the week. Slight to moderate seas are expected across the regional waters as no significant swell is expected through Tue. On Tue, long period NW swell will support seas to 8 ft from 10N to 25N W of 125W. This swell will start decaying by Thu, thus allowing seas to subside on Fri. Otherwise, a tropical wave, currently with axis along 113W will enhance winds to fresh to strong in the region from 10N to 20N between 114W and 140W tonight through Fri. Seas will generally remain near 8 ft in the vicinity of the wave. $$ KONARIK
