000 AXPZ20 KNHC 270925 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Tue Feb 27 2024 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 0915 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... An equatorial trough extends from 08N78W to 07N81W. The ITCZ stretches from 07N81W to 00N106W to beyond 03N140W. Scattered moderate to isolated strong convection is present from the equator to 07N and between 97W and 129W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A deep upper-level trough located well west of Baja California continues to transport poleward plenty of tropical moisture and along with divergence aloft result in isolated to scattered showers and ample cloudiness across NW Mexico and the offshore waters. A recent scatterometer satellite pass captured fresh to locally strong SW winds in the northern Gulf of California. Seas in these waters are 2-4 ft. The scatterometer pass also showed fresh NW-W winds off Cabo San Lucas, while moderate or weaker winds prevail in the rest of the offshore waters of Baja California. Seas in the area described are 5-7 ft. In the remainder of the Mexican offshore waters, including the Gulf of Tehuantepec and the central and southern Gulf of California, moderate or weaker winds and slight to moderate seas are prevalent. For the forecast, fresh to locally strong SW winds in the northern Gulf of California are expected to diminish early this morning. Pulsing fresh winds are forecast to develop nightly just offshore Cabo Corrientes and Cabo San Lucas through Thu. Long- period NW swell is expected to move into the outermost offshore waters north of Punta Eugenia on Wed before subsiding late Wed night. The next Tehuantepec gap wind event will occur Thu into Thu night as a strong ridge builds north of the basin supporting strong to near gale-force N winds. Conditions will improve Fri. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR A subtropical ridge over the western Atlantic sustain fresh to strong easterly trade winds across the Gulf of Papagayo region as captured by a recent scatterometer satellite pass. Seas in these waters are 5-7 ft. Fresh northerly winds are found in the Gulf of Panama, extending southward to 04N, along with seas of 3-5 ft. Elsewhere, moderate or weaker winds and slight to moderate seas continue. For the forecast, high pressure north of the area will support pulsing strong to near gale-force winds during the nights and early mornings for the next few days in the Gulf of Papagayo and downstream waters. Seas will build to around 7 ft during the strongest winds. Northerly winds in the Gulf of Panama will pulse to fresh to occasionally strong speeds at night through the next few days. ...REMAINDER OF THE AREA... The deep upper-level trough over the NW waters is producing a large area of cloudiness and isolated to scattered showers mainly north of 20N and west of 130W. A broad 1011 mb low pressure system centered near 30N125W sustains fresh to strong winds north of 25N and west of 125W. Seas in these waters are 9-13 ft as indicated by the latest altimeter satellite pass. A recent scatterometer satellite pass also depict fresh to locally strong NE winds west of 129W. Seas in the area described are 8-11 ft. The rest of the tropical eastern Pacific is under the influence of a 1019 mb high pressure system located NW of the Revillagigedo Islands. Moderate or weaker winds and moderate seas are present in the remainder of the basin. For the forecast, the aforementioned low pres is forecast to continue to weaken today as it slides eastward. The fresh to strong winds and seas to 13 ft associated with this system will diminish by tonight into Wed. Fresh to strong NW winds and seas to 11 ft in the western waters will diminish by early Wed. However, winds will increase again to fresh to locally strong in the trades waters late this week. The next cold front is set to enter the NW waters late this week and northerly swell will follow with seas increasing to at least 12 ft Fri. $$ Delgado
