000 AXPZ20 KNHC 050239 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Nov 5 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 0000 UTC surface analysis and satellite imagery through 0130 UTC. ...TROPICAL WAVES... A tropical wave is along 96W from 04N to 14N, moving west at 10 kt. Isolated moderate convection is occurring from 05N to 10N between 90W AND 104W. A tropical wave is along 118W from 06N to 17N, moving west at 10 kt. Scattered moderate isolated strong convection is noted from 07N to 18N between 108W and 123W. A tropical wave is located along 136W from 03N to 12N, moving west at 10 to 15 kt. Scattered moderate convection is occurring from 04N to 10N W of 126W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N78W to 08N84W to 07N105W to 11N117W to 08N124W. The ITCZ extends from 08N124W to 07N128W to 07N140W. Scattered moderate convection is N of 04N E of 84W. For further information on convection, see the Tropical Waves section. SCATTERED MODERATE N OF 04N E OF 84W. 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 continue to support 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 well north of the area by Thu night, and winds will increase to moderate to fresh across the central and southern Gulf waters through Sat night. For the remainder of the area, light to gentle variable winds will dominate through the weekend, except for moderate to fresh NE winds near Baja California Sur Thu night through Sat night. Slight to moderate seas to 6 ft in mainly NW swell are expected over open waters through the entire period. 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, except for Thu that seas will build to 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 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 22N 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 118W will support numerous to scattered moderate/isolated strong convection in its vicinity as it continues to move westward. $$ Ramos
