000 AXPZ20 KNHC 020315 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 143 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 0000 UTC surface analysis and satellite imagery through 0300 UTC. ...TROPICAL WAVES... A tropical wave has its axis along 99W FROM 02N to 18N, moving westward at about 15 kt. Scattered moderate to isolated strong convection is 06N to 11N between 99W and 103W. Similar convection is near 13N97W. A tropical wave has its axis along 110W from 02N to 18N, moving westward at 15-20 kt. Scattered moderate to isolated strong convection is from 10N to 16N between 108W and 116W. A tropical wave has its axis along 120W from 02N to 18N, moving westward at 15 kt. Scattered moderate to isolated strong convection is from 08N to 13N between 117W and 121W, and from 06N to 10N between 121W and 124W. A tropical wave has its axis along 140W from 01N to 19N, moving westward at 15 kt. convection is limited near the wave axis. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 11N85W to 09N93W to 12N110W to 08N130W to 09N138W. Most of the convective activity is associated with the tropical waves described above. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between high pressure centered near 33N134W and a meandering trough over the Baja California Peninsula will support gentle to moderate NW winds over the offshore waters W on Baja California during the forecast period. In the Gulf of California, gentle to moderate southerly winds will prevail in the northern part of the Gulf well into the middle part of the week while mainly gentle southerly winds are expected elsewhere. Pulsing northerly winds are expected in the Tehuantepec region tonight through Sun night, then again Mon night through Wed, as northerly winds persist in the Bay of Campeche. 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 92W. Weak tropical waves will migrate westward across Central America early in the week, and could lead to scattered shower and thunderstorm activity in a few days. Moderate southerly winds will prevail south of the monsoon trough through Wed. REMAINDER OF THE AREA... Weak high pressure of 1022 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. A shrinking area of cross- equatorial southeast swell, producing seas in the range of 7-8 ft seas, is located south of 15N and west of 130W. This area of swell will shift west of 140W during the next 6 hours. $$ GR
