000 AXPZ20 KNHC 270817 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 722 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 0600 UTC surface analysis and satellite imagery through 0800 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from low pres 1009 mb near 10N74W to 07N78W to 05N96W. The ITCZ continues in segments from 05N96W to 07N106W, from 05N109W to 08N127W and from 07N132W to beyond 06.5N140W. Low pres 1011 mb near 06N107W and low pres 1010 mb near 08N129W split the ITCZ. Scattered moderate and isolated strong convection is present within 150 nm either side of the trough and ITCZ between 82W and 102W and also within 240 nm either side of the ITCZ between 102W and 125W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Light to gentle winds generally prevail over the forecast waters. 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 32N132W to near the Revillagigedo Islands through Fri. A pulse of strong to near gale force N to NE winds is expected over the Gulf of Tehuantepec today. NW swell will move into the waters off Baja California Norte Mon through Tue night, causing seas N of 29N and E of 125W to build to between 8 and 9 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 17N121W. Estimated minimum central pressure is 1010 mb. Maximum sustained wind speed is 25 kt with gusts to 35 kt. This system is only retaining shallow convection and continues to weaken as it moves WNW. This system will dissipate by Tue. High pressure prevails over the northern waters. Away from the wind field of Post-Tropical Cyclone One-E, gentle to moderate winds prevail across the discussion area. Seas are in the 5-8 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. $$ CAM
