000 AXPZ20 KNHC 242014 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 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 1800 UTC surface analysis and satellite imagery through 1900 UTC. ...TROPICAL WAVES... A tropical wave has its axis along 89W/90W, just northeast of the Galapagos Islands, north of 01N to across El Salvador and Guatemala, and is moving west at around 10 kt. Associated convection is described below. A tropical wave has its axis near 112W, southwest of the Revillagigedo Islands, from 01N to 16N, and is moving west at around 10 kt. Associated convection is described below. A tropical wave is along 119W/120W, from 01N to 21N, drifting west at around 5 kt. Associated convection is described below. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 12N87W to 13N100W to 11N117W to 12N130W to 14N136W to 11N140W. Scattered moderate and isolated strong convection is noted from 06N to 14N between 83W and 99W, and from 06N to 16N between 112W and 126W. Isolated to scattered moderate convection is noted from 07N to 10N between 99W and 107W, and from 07N to 10N between 125W and 130W. 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 to locally fresh SE winds are present in the northern Gulf, with gentle to moderate elsewhere. 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 persist into the evening, then occur again Sat and Sat night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... A brief surge of fresh to strong SW winds near the Papagayo region is occurring this afternoon in the wake of a tropical wave. Light to gentle variable winds are north of the monsoon trough, with seas of 4 to 6 ft in SW swell. South of the monsoon trough, gentle to locally moderate southerly winds prevails, with seas of 5 to 7 ft in S to SW swell, except 3 to 5 ft offshore Colombia. 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. 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 are increasing to locally fresh this evening, and these winds combined with southerly swell are leading to a period of seas in the vicinity of 7 to 9 ft through Thu evening. No major changes in the marine conditions are expected elsewhere. $$ Lewitsky
