000 AXPZ20 KNHC 271504 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Mon Apr 27 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 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from the Colombia/Panama border near 08N78W to 05N96W. The ITCZ continues from 05N96W to 07N107W then resumes from 05N112W to 08N127W then resumes from 08N132W to 06N140W. Scattered moderate and isolated strong convection is from 06N to 10N between 78W and 91W, from 03N to 13N between 93W and 101W, from 02N to 10N between 107W and 117W, and from 07N to 10N between 122W and 126W. Low pressure 1010 mb near 08N130W has associated scattered moderate and isolated strong convection from 07N to 10N between 128W and 132W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A pulse of strong to near gale force N to NE winds will persist into early afternoon over the Gulf of Tehuantepec with a cold front N of the area in the SW Gulf of Mexico. Gentle to moderate winds generally prevail over the forecast waters outside of the Tehuantepec region. Seas range between 5 and 7 ft west of Baja California Norte and 4 to 6 ft elsewhere. Inside the Gulf of California seas are in the 1 to 3 ft range. Weak surface troughing will remain near the Baja Peninsula through the end of the week. A high pressure ridge will remain in place from roughly 32N133W to near the Revillagigedo Islands through Fri. NW swell will move into the waters off Baja California Norte early this week, causing seas N of 29N and E of 125W to build to between 6 and 8 ft during this time frame. A round of NW to N swell will move into the waters off Baja California Norte Thu through Sat night, causing seas N of 24N and E of 125W to build to between 8 and 10 ft. Otherwise fairly tranquil marine conditions will prevail elsewhere this week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A weak pressure pattern is resulting in mostly light to gentle winds across the forecast waters. Seas are mainly 3 to 5 ft in a mix of long period S and NW swell. Fairly tranquil marine conditions are expected across most of the forecast area through Thu, except for the Papagayo region, where fresh to strong gap winds will prevail through Fri night. REMAINDER OF THE AREA... Post-Tropical Remnant Low One-E is centered near 17N122W. Estimated minimum central pressure is 1011 mb. Associated winds have likely diminished to moderate to fresh early this morning, however a recent altimeter pass indicated lingering seas around 8 to 9 ft within 90 nm of the low. This low is only retaining shallow convection and continues to weaken as it moves WNW. This low will dissipate by Tue. High pressure prevails over the northern waters. Away from the compact wind field of Post-Tropical Remnant Low One-E, gentle to moderate winds prevail across the discussion area. Seas are in the 5 to 8 ft range. Gentle to moderate winds will prevail from 05N to 20N W of 120W through mid week. High pressure to the N of this region will build by mid week as a low currently passing along the northern flank of the high moves away toward the NE. The rebuilding high will cause trade winds in this region to become moderate to fresh during the second half of this week. A set of NW swell will breach southeast of 30N140W Wed, decaying by early Thu. A different set of fresh northerly swell will spread southward into the area from off of southern California early this week, decaying by mid-week, then returning by the end of the week. $$ Lewitsky
