000 AXPZ20 KNHC 250325 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 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 0000 UTC surface analysis and satellite imagery through 0230 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 13.5N122W. Scattered moderate isolated strong convection is noted from 12.5N to 17N between 116W and 122W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N74W to 09N80W to 08N103W to 1011 mb low pres near 13.5N122W to 07.5N126W. The ITCZ continues from 07.5N126W to 10N133W to beyond 08N140W. Widely scattered moderate convection is N of 04.5N E of 81W and across portions of the Gulf of Panama. Scattered moderate isolated strong convection is noted from 07N-16N between 99W-111W, from 12N-17N between 111W-122W, and from 08N-12.5N between 127W-139W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Moderate to strong NE gap winds across the Gulf of Tehuantepec N of 14.5N will continue overnight through Wed morning, then diminish to 10 kt or less Wed afternoon. Seas across the Gulf are currently near 6 ft. However seas of 7-8 ft extend will downstream of the Gulf from 05N to 14N, and will diminish to 6 ft or less across the entire area by Wed morning. Fresh to strong northerly gap winds are expected to return across the Gulf N of 14.5N Wed night through Fri morning. 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 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. 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 night and invade the waters of Central America Fri night, raising seas to 6-7 ft. REMAINDER OF THE AREA... A broad ridge extends from a 1034 mb high near 42N145W southeastward to 30N128W to 15N105W. 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 115W, 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 mid week to maintain seas near 8 ft across the northern waters north of 26N. Large NW swell will then move into the northern waters late Wed. Seas will peak 10-16 ft over the northern waters N of 20N and E of 130W early Thu into Fri. $$ Stripling
