903 AXPZ20 KNHC 102038 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2205 UTC Thu Jul 10 2025 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 2000 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 88W north of 07N, moving west at around 10 kt. Scattered moderate and isolated strong convection is noted from 04N-08N between 87W-95W. The axis of a tropical wave is near 106W north of 08N, moving westward at around 10 kt. Scattered moderate and isolated strong convection is noted from 07N-17N between 101W-109W. The axis of a tropical wave is near 117W from 07N-15N, moving westward at around 10 kt. Scattered moderate and isolated strong convection is noted from 07N-15N between 118W-125W. The axis of a tropical wave is near 128W from 05N-14N, moving westward at around 10 kt. Scattered moderate and isolated strong convection is noted from 09N-13N between 125W-129W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from coastal Panama near 08N78W to 10N124W. The ITCZ continues from 10N130W to 09N140W. Scattered moderate and isolated strong convection is noted from north of 04N east of 83W, 04N-08N between 87W-95W, from 07N-17N between 101W-109W, from 07N-15N between 118W-125W, from 09N-13N between 125W-129W, and from 05N-12N west of 135W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Fresh N gap winds over the Gulf of Tehuantepec with seas 6-7 ft are occurring this afternoon. Fresh to strong SE winds over the N and central Gulf of California with seas 3-6 ft exist. Elsewhere winds are gentle to moderate with seas 4-6 ft in mixed swell over forecast waters. For the forecast, a low pressure system over the SW United States will maintain the fresh to strong SE winds over the N and central Gulf of California through Sat morning. Mainly gentle to moderate winds will prevail elsewhere through early next week. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gentle to moderate NE to E winds are occurring north of the monsoon trough and gentle to moderate SE to SW winds are found south of the monsoon trough. Seas are 5-7 ft in S to SW swell. For the forecast, the moderate to fresh E gap winds will continue across the Gulf of Papagayo region through Sat morning. Gentle to moderate winds will prevail elsewhere over forecast waters for the next few days. Moderate SW swell currently impacting the equatorial zones should diminish on Sat. Looking ahead, a resumption of the fresh E gap winds over the Gulf of Papagayo region may occur starting Mon night. ...REMAINDER OF THE AREA... A 1034 mb high is centered at 39N141W with a surface ridge extending to 30N125W to 19N110W. The moderate pressure gradient between the ridge and lower pressure over the ITCZ/monsoon trough is producing only moderate to locally fresh winds across forecast waters. South of 02N and west of 100W, seas are 8-10 ft in SE to S swell. Elsewhere, seas are 5-7 ft in mixed swell. For the forecast, little change to winds and wind waves are expected for the next few days. The large SE to S swell will diminish some by Fri afternoon, before being enhanced again starting Sat night. $$ Landsea
