000 AXPZ20 KNHC 031430 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Mon Jun 3 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 1200 UTC surface analysis and satellite imagery through 1430 UTC. ...TROPICAL WAVES... The axis of a tropical wave is analyzed near 102W from 04N to 16N. It is moving westward at about 5 to 10 kt. Scattered moderate to isolated strong convection is within 75 nm west of the wave axis. Environmental conditions do not appear conducive for significant development, and the system is expected to weaken during the next day or so as it moves little. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N86W to 12N103W to 07N140W. Scattered moderate and isolated strong convection is noted from 05N to 09N E of 97W, and from 06N to 12N between 100W and 140W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge extends from high pressure centered well northwest of the region to near the Revillagigedo Islands. The pressure gradient between the area of high pressure and a trough over the Gulf of California is supporting moderate to fresh northwesterly winds across the Baja California waters extending southward to near the Revillagigedo Islands. Light to gentle winds prevail over the remainder of the discussion waters. Seas are in the 7 to 9 ft range in NW swell off Baja California Norte, and 6 to 7 ft off Baja California Sur. Elsewhere over the open waters off Mexico, seas are in the 4 to 6 ft range in southwest swell. Seas of 3 ft or less are over the Gulf of California. Hazy conditions persist off southern Mexico, including the Gulf of Tehuantepec, due to agricultural fires over southern Mexico and Central America. Visibilities may decrease at times to around 5 nm. For the forecast, moderate to fresh NW to N winds will prevail off the Baja California waters through Tue night, then mostly moderate W to NW winds afterwards. Fresh NW winds are expected at night and into the mornings offshore Cabo San Lucas during the forecast period. Elsewhere, light to gentle winds will prevail across the open waters. Seas of 6 to 9 ft in NW swell will continue off of Baja California Norte through this afternoon. Hazy conditions, dense at times, may persist off southern Mexico, including the Gulf of Tehuantepec, due to agricultural fires over S Mexico and Central America. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle winds are found N of the monsoon trough. Gentle to moderate winds prevail S of the monsoon trough. Seas are in the 4 to 6 ft range in long-period S to SW swell. Hazy conditions continues off the Central American coast due to agricultural fires in southern Mexico and Central America. Visibilities may decrease at times to around 5 nm or less. For the forecast, light to gentle winds will prevail N of the monsoon trough. Gentle to moderate winds are expected S of the monsoon trough for the next several days. Hazy skies from smoke caused by agricultural fires over Mexico and Central America may reduce visibilities over portions of the Central American offshore waters the next few days. ...REMAINDER OF THE AREA... High pressure prevails over the waters N of 20N. The pressure gradient between the area of high pressure and lower pressure within the monsoon trough is supporting moderate to fresh NE to E winds N of the monsoon trough to 20N and W of 120W. Seas with these winds are in the 8 to 10 ft range. Gentle to moderate winds are elsewhere N of the monsoon trough with seas of 6 to 8 ft in north to northeast swell across all but the far NW waters, where seas are in the 5 to 6 ft range. Gentle to moderate winds and seas of 5 to 6 ft prevail S of the monsoon trough. For the forecast, the fresh to strong NE to E winds over the western part of the area are forecast to diminish to mostly fresh speeds this afternoon. The associated seas will slowly subside through Tue. Otherwise, little change is expected to the current conditions over much of the area the next few days. $$ AL
