000 AXPZ20 KNHC 042115 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 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 1800 UTC surface analysis and satellite imagery through 2100 UTC. ...TROPICAL WAVES... The axis of a tropical wave is analyzed near 108W 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 13N87W to 13N100W to 09N124W. The ITCZ extends from 09N124W to beyond 08N140W. Scattered moderate to isolated strong convection is noted from 06N to 15N between 82W and 101W. Similar convective activity is seen in the Gulf of Panama. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A ridge extends from high pressure centered located W of area near 31N145W to near the Revillagigedo Islands. The pressure gradient between the area of high pressure and a trough over the Gulf of California is supporting gentle to moderate northwesterly winds within about 60-75 nm of the coast of Baja California, and moderate to locally fresh winds elsewhere across the offshore forecast waters. Light to gentle winds prevail over the Gulf of California and the remainder of the Mexican offshore waters. Seas are in the 6 to 8 ft range in NW swell off Baja California Norte, and 5 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, reducing visibility to around 3 nm at times. For the forecast, moderate to fresh NW to N winds will continue off the Baja California waters through tonight, with mostly moderate 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 5 to 7 ft are expected off of Baja California Norte through Thu morning. Then, another swell event will bring seas of 8 to 9 ft N of Punta Eugenia later on Thu. Hazy conditions due to agricultural fires over southern Mexico will continue for the next couple of days, reducing visibility to around 3 nm at times. ...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 with axis around 09N. Moderate to locally fresh winds prevail S of the monsoon trough. Scattered moderate convection is noted across the offshore forecast waters from Guatemala to Costa Rica and in the 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 conditions from smoke caused by agricultural fires over Mexico and Central America may reduce visibilities mainly over the northern Central American offshore waters over the next couple of days. ...REMAINDER OF THE AREA... High pressure of 1027 mb located W of area near 31N145W dominates the region N of 15N and W of 110W. 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 130W. 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. A new swell event will reach the NW waters on Wed, and propagate across the area N of 25N on Thu, building seas to 8 to 11 ft between 120W and 130W. Seas are expected to subside below 8 ft late on Fri. $$ GR
