000 AXPZ20 KNHC 030943 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1005 UTC Mon Jun 03 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 0930 UTC. ...TROPICAL WAVES... The axis of a tropical wave is analyzed near 101W from 04N to 16N. It is moving westward at about 5 to 10 kt. Disorganized scattered moderate to isolated strong convection is seen within 60 nm of 12N103W. Scattered moderate convection is within 60 nm of 08N102W. Environmental conditions do not appear conducive for significant additional development of this system as it is expected to weaken during the next few days as it moves little. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from low pressure over northern Colombia to 09N84W to 09N90W to 11N99W to 10N105W to 10N116W to 09N122W to low pressure near 08N131W 1011 mb and to beyond 08N140W. Scattered moderate to strong convection is within 120 nm south of the trough between 100W and 108W. Scattered moderate to isolated strong convection is within 120 nm north of the trough between 99W and 102W. also within 60 nm north of the between 109W and 113W, and within 60 nm south of the trough between 118W and 121W. Scattered moderate convection is within 60 nm north of the trough between 118W and 125W, also between 136W and 140W and within 60 nm south of the between 118W and 120W. ...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 6 to 9 ft range in NW swell off Baja California Norte, and 6 ft off Baja California Sur. Elsewhere over the open waters off Mexico, seas are in the 5 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 through the week. 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... Gentle NE winds are over the Gulf of Papagayo, with light to gentle winds elsewhere 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 fresh to locally strong NE to E winds N of the monsoon trough to 21N and W of 120W. Seas with these winds are in the 8 to 10 ft range. Gentle to moderate winds elsewhere N of the monsoon trough. Elsewhere N of the monsoon trough seas of 6 to 8 ft in north to northeast swell prevail 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. $$ Aguirre
