000 AXPZ20 KNHC 262043 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Thu Nov 26 2020 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 2040 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 09N84W to 07N94W to 12N122W to 10N127W. The ITCZ continues from 10N127W to beyond 09N140W. Scattered moderate isolated strong convection is noted from 04N to 09N east of 86W. Scattered moderate convection is noted from 05N to 10N between 90W and 96W. Scattered moderate isolated strong convection is noted from 10N to 12N between 104W and 110W and from 08N to 10N between 130W and 140W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gentle to moderate NW winds over the central and southern Gulf of California, and the waters west of the Baja California will persist through this evening as a broad high pressure ridge prevails across the regional waters. Fresh to locally strong NW winds will develop over the northern Gulf of California tonight, spreading southward through Fri evening and then persisting through early Mon. Seas are expected to build to 5-8 ft inside the Gulf of California Fri through early Mon. Moderate N to NE winds will prevail across the waters of Baja California, with strong NE winds shooting through the gaps between the higher elevations of Baja and extending 90 nm offshore. Large NW swell has propagated into the Baja California Norte waters, and will spread across the Baja Sur waters early Fri through Sat evening. Peak seas are peaking near 13 ft west of Baja California Norte, and will start to subside Fri. Fresh to strong north winds will prevail across the Gulf of Tehuantepec within 150 nm of the coast through Fri morning. Nocturnal pulses of moderate to fresh north winds can be expected thereafter through Sun. A strong cold front is expected to move across the Gulf of Mexico this weekend and produce another gale force gap wind event across Tehuantepec beginning early Mon, then diminish below gale force Tue. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Moderate NE to E winds will pulse to fresh each night into the early morning hours over the Papagayo region. Otherwise expect moderate to locally fresh S to SW winds south of 10N. Moderate cross equatorial swell has moved into the waters off Ecuador and Colombia. This swell will propagate into the waters of Central America Fri, building seas to 6-7 ft before subsiding Sun into early next week. REMAINDER OF THE AREA... Elongated surface low pressure is centered on a 1012 mb low near 16N125W. Fresh to strong winds are noted within 120 nm NW quadrant of the low. Scattered showers and thunderstorms are noted within 300 nm across the northeast quadrant of the low. The low will shift westward tonight before dissipating Fri. A broad ridge extends from a 1033 mb high near 38N135W southeastward across the waters off Baja California Norte to near the Revillagigedo Islands. A dry cold front extends from 30N117W to 28N122W. The pressure gradient between the ridge and lower pressure within the monsoon trough and in the vicinity of the ITCZ is producing mainly moderate to fresh NE trades across the area waters north of 10N and west of 120W. Seas are generally 7-10 ft across this area except 10-13 ft across the waters N of 26N where large NW swell prevails. NW swell is propagating across the N waters, with seas to 10 to 13 ft ft north of 26N and west of 120W. The NW swell will continue to spread south- southeastward across the northern waters, peaking near 14 ft over the northern waters N of 20N and E of 132W tonight into Fri. Seas will slowly decay into the weekend. Looking ahead, another pulse of NW swell with seas up to 8 ft is forecast to push southeast of 30N140W Sat night through Sun night, with larger NW swell moving southeast into the area early next week. $$ AL
