000 AXPZ20 KNHC 042206 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 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 1800 UTC surface analysis and satellite imagery through 2115 UTC. ...TROPICAL WAVES... A tropical wave is along 94W from 03N to 14N, moving west at 10 kt. Isolated moderate convection is occurring from 05N to 15N between 89W AND 102W. A tropical wave is along 117W from 06N to 17N, moving west at 10 kt. Numerous moderate and scattered strong convection is noted from 08N to 19N between 109W and 123W. A tropical wave is located along 135W from 03N to 11N, moving west at 10 to 15 kt. Scattered moderate convection is occurring from 05N to 10N between 126W and 137W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 08N90W to 07N103W to 11N116W to 09N123W. The ITCZ extends from 09N123W to 07N128W to 06N140W. Scattered moderate convection is from 03N to 07N E of 86W. For further information on convection, see the Tropical Waves section. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gulf of Tehuantepec: Surface ridging will be the dominant feature in the Gulf of Mexico through the upcoming weekend. This will allow the continuation of strong to near gale force gap winds in the Gulf of Tehuantepec for the rest of the week. It is possible for gale force winds to resume Friday night as a front moves across the SW Gulf of Mexico. 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 to 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. However, seas are expected to be below 8 ft. Farther south, gentle to moderate S-SW monsoonal flow will continue across the offshore forecast waters of Costa Rica, Panama, Colombia and Ecuador through the upcoming weekend. REMAINDER OF THE AREA... Surface ridging over the northern forecast waters will maintain a modest pressure gradient and moderate to fresh tradewinds S of 27N and 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 117W will support numerous to scattered moderate/isolated strong convection in its vicinity as it moves westward. $$ Ramos
