000 AXPZ20 KNHC 020906 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 713 UTC Sun Aug 2 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 0900 UTC. ...TROPICAL WAVES... A tropical wave is along 100W/101W from 02N to 18N, moving westward at about 15-20 kt. Convection is limited near the wave axis. A tropical wave has its axis along 112W from 02N to 18N, moving westward at 15 kt. Scattered moderate convection is noted near the northern end of the wave axis from 13N to 16N between 110W and 112W. A tropical wave has its axis along 122W from 02N to 18N, moving westward at 15 kt. Scattered moderate to isolated strong convection is from 08N to 10N between 121W AND 124W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 12N87W to 09N98W to 12N112W to 09N122W to 10N140W. Scattered moderate isolated strong convection is N of 07N E of 80W, including the Panama Canal. Similar convection is also noted from 08N to 11N between 116W and 120W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between high pressure of 1023 centered near 34N134W and a meandering trough over the Baja California Peninsula will support gentle to moderate NW winds over the offshore waters W on Baja California through early Wed. A stronger high pressure center will begin to dominate the forecast area by mid week, resulting in moderate to fresh NW-N winds N of Punta Eugenia, with seas building to 8 ft. Between June and October, the prevailing winds in the Gulf of California are mostly SE. Gentle to moderate SE-S winds are expected in the northern part of the Gulf well into the middle part of the week, while mainly gentle SE-S winds are forecast elsewhere. Pulsing northerly winds are expected in the Tehuantepec region during the overnight and early morning hours through Wed, as northerly winds persist in the Bay of Campeche. Seas are forecast to remain in the 5-7 ft range. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... A monsoon trough axis stretches roughly along 09N to 10N east of 100W. Recent scatterometer data showed mainly moderate S-SW winds S of the monsoon trough, and light westerly winds N of the monsoon trough. As it is normal for this time of the year, tropical waves will continue to migrate westward across Central America into the east Pacific region, helping to induce some convective activity across the area. REMAINDER OF THE AREA... Weak high pressure of 1023 mb dominates the northern forecast waters N of 20N W of 120W. The pressure gradient between the ridge and lower pressure associated to the monsoon trough is supporting moderate to fresh trade winds north of the trough axis to 18N, and west of about 120W. By mid week, a stronger high pressure center will extend a ridge across the forecast waters. Moderate to locally fresh NE winds associated with this system will briefly build seas to 8 ft across the NW waters, particularly from 23N to 26N W of 137W by Mon night. $$ GR
