650 AXPZ20 KNHC 260951 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Wed Oct 26 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 0600 UTC surface analysis and satellite imagery through 0855 UTC. ...TROPICAL WAVES... A tropical wave has its axis along 111W, south of 17N, moving W at 10 kt. Scattered showers are occurring near the trough axis, primarily from 06N to 14N and between 107W and 117W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of Costa Rica near 09N85W to 11N100W to a 1012 mb low pres near 11N121W to another 1012 mb low pres near 11N136W to 09N140W and beyond. Isolated to scattered moderate showers are seen from 08N to 12N and between 90W and 107W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... High pressure over the north Pacific sustains moderate to fresh NW-N winds across the offshore waters of Baja California, as noted in a recent scatterometer satellite pass, mainly N of Cape San Lazaro. Stronger winds are also occurring north of the offshore waters and seas are beginning to respond. Overall, seas are 5-7 ft across these offshore waters. In the remaining offshore waters of Baja California, light to gentle northerly winds and seas of 4-6 ft prevail. Moderate NW winds are found in the Gulf of California, mainly in the central and southern portions of the basin. Seas are 3-4 ft. Elsewhere in the Gulf, light to gentle variable winds and seas of 1-3 ft. In the offshore waters of Mexico, including the Gulf of Tehuantepec, light to gentle westerly winds and seas of 3-5 ft are prevalent. For the forecast, moderate to fresh N-NW winds are expected across most of the offshore waters of Baja California through early next week, decreasing somewhat Thu into Fri. Seas are forecast build to 10 ft early Thu, subsiding below 8 ft early Fri. Building high pressure behind a cold front forecast to move across the Gulf of Mexico this weekend will result in an increase in winds and seas in the Gulf of Tehuantepec. Wind gusts to gale force are possible. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Scattered showers and isolated thunderstorms continue along the coasts of Costa Rica, Panama and NW Colombia, affecting the nearshore waters. Generally tranquil weather conditions are present away from the monsoon trough in the rest of the basin. A recent scatterometer satellite pass indicate that moderate southerly winds are present south of 11N. Seas in these waters are 4-6 ft, with the highest seas occurring south of the Galapagos Islands. Elsewhere, light to gentle winds and seas of 3-5 ft prevail. For the forecast, moderate to fresh southerly winds and moderate seas will continue south of the monsoon trough through the rest of the week, diminishing into the weekend. Light winds in the Papagayo region will pulse to fresh NE-E winds on Sun and into early next week. REMAINDER OF THE AREA... The pressure gradient between the high pressure over the north Pacific and lower pressures in the deep tropics continue to support moderate to fresh easterly winds N of 11N and W of 110W. This was recently captured by a scatterometer satellite pass. Seas in these waters are 6-8 ft, with the highest seas occurring near 17N128W based on the latest altimeter satellite pass. South of the monsoon trough, moderate to fresh southerly winds are observed, along with seas of 6-8 ft. Elsewhere, moderate or weaker winds and seas of 4-6 ft are prevalent. For the forecast, the ridge supporting the wind regime over the waters north of the monsoon trough and W of 110W will gradually weaken as it moves eastward. A new set of long-period northwest swell will build wave heights to the range of 7-10 ft over the NE part of the remainder of the area waters beginning Wed night. $$ DELGADO
