000 AXPZ20 KNHC 040353 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 0405 UTC Tue Jun 04 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 0000 UTC surface analysis and satellite imagery through 0345 UTC. ...TROPICAL WAVES... The axis of a tropical wave is analyzed near 105W from 04N to 16N, moving westward at about 5 to 10 kt. Scattered moderate to isolated strong convection is along the wave axis within 60 nm of 13N105W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from low pressure of 1007 mb over northwest Colombia to 09N84W to 09N92W to 12N101W to 10N116W to low pressure of 1011 mb near 09N125W and to 09N130W. The ITCZ extends from 09N130W to beyond 08N140W. Scattered moderate to strong convection is seen within 60 nm of trough between 82W and 86W, and within 60 nm south of trough between 93W and 97W. Scattered moderate to isolated strong convection is within 180 nm south of the trough between 105W and 108W. Scattered moderate convection is within 60 nm north of the trough between 125W and 128W and between 133W and 137W. ...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 8 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 6 nm. For the forecast, moderate to fresh NW to N winds will prevail off the Baja California waters through Tue night, with mostly moderate W to NW winds afterwards. Fresh NW winds are expected to pulse 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 7 to 9 ft in NW swell will continue off of Baja California Norte through Thu night before subsiding to below 8 ft Fri night. 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 continue off the northern Central American coast due to agricultural fires in southern Mexico and Central America. 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 mainly over the northern Central American offshore waters through the rest of the week. ...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 4 to 6 ft range. Gentle to moderate winds and seas of 5 to 7 ft prevail S of the monsoon trough. For the forecast, seas over the trade wind zone in the western waters will slowly subside through Tue. Otherwise, little change is expected to the current conditions over much of the area the next few days. $$ Aguirre
