000 AXPZ20 KNHC 041533 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 1605 UTC Tue Jun 4 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 1530 UTC. ...TROPICAL WAVES... The axis of a tropical wave is analyzed near 107W from 05N to 15N. It is moving westward at about 5 to 10 kt. Scattered moderate to isolated strong convection is noted from 11N to 14N between 105W and 111W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from the coast of Nicaragua near 12N87W to 15N104W to 08N128W. The ITCZ extends from 08N128W to beyond 06N140W. Scattered moderate to isolated strong convection is noted from 04N to 16N between 83W and 101W. ...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 locally 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 continue off the Baja California waters through tonight, 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 rest of the week and into the upcoming weekend. 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 around 09N. Moderate to locally fresh winds prevail S of the monsoon trough. Scattered storms are noted across the offshore waters from Guatemala to Costa Rica in addition to the coast of Colombia and Gulf of Panama. 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 09N. Moderate to locally fresh winds are expected S of 09N for the next several days. Scattered storms are expected to continue over the Central America offshore waters through Thu. Meanwhile, 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 25N and W of 120W. Seas with these winds are in the 8 to 9 ft range in N to NE swell. 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 gradually subside through Wed. Northwesterly swell will begin to move across the waters N of 23N from Wednesday through Thu night where it will move from 140W eastward to 120W. Seas will build 8 to 11 ft, and subside below 8 ft by Fri. $$ AReinhart
