000 AXPZ20 KNHC 241455 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Wed Aug 24 2022 Tropical Weather Discussion for the eastern Pacific Ocean from 03.4S to 30N, east of 120W including the Gulf of California, and from the Equator to 30N, between 120W and 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 1430 UTC. ...TROPICAL WAVES... A tropical wave has its axis along 88W/89W, N of 02N across El Salvador and into the far northwestern Caribbean, and is moving W at around 10 kt. Scattered moderate to isolated strong convection is noted from 05N to 16N between 80W and 101W. A tropical wave has its axis near 111W, from 01N to 16N, and is moving W at around 10 kt. Associated convection is described below. A tropical wave is along 119W, from about 02N to 21N, drifting W at around 5 kt. Scattered moderate to isolated strong convection is noted from 05N to 14N between 111W and 121W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 11N86W to 12N110W to 14N136W to 13N140W. Aside from the convection associated with the tropical waves, scattered moderate to isolated strong convection is noted from 14N to 16N between 121W and 125W, and from 14N to 16N between 133W and 137W. Scattered moderate convection is noted from 02N to 07N between 77W and 80W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Weak surface ridging extending across the offshore waters from the northwest is supporting mainly light to gentle winds. Seas are 4 to 6 ft in mainly long-period SW swell, except to 7 ft offshore Baja California Norte in NW swell. In the Gulf of California, moderate SE winds are present, except gentle in the southern Gulf. Seas are 3 ft or less north of the entrance. For the forecast, a weak pressure gradient is forecast to prevail across the region and support mainly gentle NW winds and slight to moderate seas across the Baja California peninsula offshore waters north of Cabo San Lazaro through Thu night, before high pressure building SW toward the area leads to winds increasing to moderate to fresh Fri and Fri night. Light to gentle variable winds elsewhere, except for the Gulf of California where moderate to locally fresh SE winds will develop today and again on Sat. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle variable winds are north of the monsoon trough, with seas around 5 ft in SW swell. South of the monsoon trough, gentle to locally moderate southerly winds prevails, with seas of 4 to 7 ft in S to SW swell. For the forecast, mainly gentle winds are expected across the offshore forecast waters into the weekend, although periods of moderate S winds will impact areas offshore Colombia and Ecuador. Southerly swell with moderate seas will propagate across the Ecuador, The Galapagos, and Colombia offshore waters through the end of the week. REMAINDER OF THE AREA... High pressure centered well north of the area continues to dominate the weather pattern for waters north of the monsoon trough and west of 120W, with moderate to locally fresh NE winds and seas of 4 to 7 ft, locally 8 ft near 30N124W. Mainly gentle winds and 5 to 6 ft seas are elsewhere north of the monsoon trough. Gentle to moderate southerly winds and seas of 5 to 8 ft are south of the monsoon trough in SW swell, highest near and along 03.4S. For the forecast, surface ridging will continue to dominate the forecast region north of the monsoon trough through the next several days. Southerly winds south of the monsoon trough and east of 120W may increase to fresh today, and these winds combined with southerly swell may lead to a period of seas in the vicinity of 7 to 9 ft. No major changes in the marine conditions are expected elsewhere. $$ Lewitsky
