000 AXPZ20 KNHC 260903 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 841 UTC Sun Apr 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 0600 UTC surface analysis and satellite imagery through 0800 UTC. ...SPECIAL FEATURES... Tropical Depression One-E is centered near 14.8N 117.5W at 26/0300 UTC moving NW at 7 kt. Estimated minimum central pressure is 1006 mb. Maximum sustained wind speed is 30 kt with gusts to 40 kt. Scattered moderate convection is observed in the SE quadrant within 120 nm. The depression is forecast to continue on a NW track the next day or so with winds to 30 kt. On Sunday, an increase in vertical wind shear and lower sea surface temperatures is expected to lead to the weakening of the depression. The depression is expected to dissipate by Mon night. See latest NHC forecast/advisory under AWIPS/WMO headers MIATCMEP1/WTPZ21 KNHC for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from low pres 1008 mb near 10N74W to 05N92W to low pres 1009 mb near 08N103W to 05N106W. The ITCZ continues in segments from 05N106W to 04N109W to 09N126W and from 08N128W to beyond 06N140W. A surface trough extending from 07N127W to 11N126W splits the ITCZ. Scattered moderate and isolated strong convection is seen within 45 nm either side of a line from 03.5N80W to 06.5N90W, from 06N to 10N between 102W and 106W and from 07N to 09N between 120W and 126W. Scattered moderate convection is found from 03N to 05N between 97W and 103W. 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 running 1 to 3 ft. Weak surface troughing will remain near the Baja Peninsula region through at least mid week. High pressure will gradually build toward the region from the west for the next several days. A pulse of fresh to strong N winds is expected to pass over the Gulf of Tehuantepec tonight and Monday morning. Fairly tranquil marine conditions will prevail elsewhere through the middle of next 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 Thu night. REMAINDER OF THE AREA... Please see special features above for more on TD One-E. High pressure centered over the NE Pacific near 33N134W ridges SE over the Revillagigedo Islands. The high is being weakened by low pres passing over the NE Pacific toward the Gulf of Alaska. Away from the wind field of T.D. 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 will build by mid week as the low 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 the week. Long period NW swell will maintain combined seas of 6 to 8 ft west of 120W this weekend. S swell will support seas to 7-8 ft in the equatorial waters west of 100W today. $$ CAM
