000 AXPZ20 KNHC 250926 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Wed Nov 25 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 0600 UTC surface analysis and satellite imagery through 0830 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 122W, from 06N to 17N, moving west around 10 kt. A 1011 mb low pressure center associated with this wave is located near 14N122W. Scattered moderate isolated strong convection is noted from 12N to 16.5N between 116W and 122W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N74W to 08.5N97W to 1011 mb low pres near 14N122W. The ITCZ continues from 13.5N123W to beyond 08N140W. Scattered moderate to strong convection is N of 05N E of 80W and across portions of the Gulf of Panama. Scattered moderate isolated strong convection is noted from 08N-13.5N between 99W-100W, from 10N- 18N between 100W- 122W, and from 08N-12.5N between 126W-137W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gentle to moderate NW winds over the Gulf of California and the waters west of the Baja California peninsula will persist through Thu as a broad high pressure ridge prevails across the regional waters. Thu night a cold front will usher fresh to strong NW winds that will spread down the entire length of the Gulf of California through Sun night. Seas are anticipated to build to 6-8 ft inside the Gulf of California Fri through Sun. Moderate NW swell currently prevailing west of Baja California Norte will diminish briefly Wed, before large NW swell invades all of the Baja offshore waters Thu morning through Fri night. Peak seas are anticipated to be near 13 ft Thu night west of Baja California Norte. Northerly gap winds have diminished to 10 kt tonight across the Gulf of Tehuantepec and will remain light through this evening. Fresh to strong north winds are expected to return across the Gulf from Wed night through Fri morning. Looking ahead, 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 next Wed. 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 over the Papagayo region through Fri night. Otherwise expect gentle to moderate S to SW winds south of 10N. Moderate cross equatorial swell is expected to move into the equatorial waters off Colombia Thu evening and invade the waters of Central America Fri, raising seas to 6-7 ft. REMAINDER OF THE AREA... A broad ridge extends from a 1034 mb high near 40N142W southeastward to 30N132W to 15N110W. The pressure gradient between the ridge and lower pressure within the monsoon trough and in the vicinity of the ITCZ is producing moderate to fresh NE trades across the area waters north of 10N and west of 118W, as seen by recent scatterometer passes. Seas are generally 7-9 ft across this area. These conditions will change little through Wed. Fresh NW swell has propagated into the far NW waters, with seas to 9 ft, and will spread southeastward through Wed to maintain seas near 8 ft across the northern waters north of 25N. Large NW swell will then move into the northern waters late Wed. Seas will peak 10-15 ft over the northern waters N of 20N and E of 132W early Thu into Fri. $$ Stripling
