Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Tue May 7 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 0350 UTC.


...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from 10N74.5W to 12.5N83W to 07N95W to 11N104W to low pres 1009 mb near 09N109W to low pres 1011 mb near 07N118.5W. The ITCZ extends from 07N122W to 07.5N130W to beyond 08N140W. Scattered moderate isolated strong convection is noted from 04N to 09N between 83W and 102W, and from 04N to 16N between 103W and 118W.


...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure centered north of Hawaii extends a broad ridge southeastward over the offshore waters of Mexico to near the Revillagigedo Islands. The pressure gradient between the high pressure and lower pressure across interior Mexico is supporting moderate to locally fresh NW winds offshore the peninsula, with fresh winds mainly between Punta Eugenia and Cabo San Lazaro. Seas with these winds are in the range of 6 to 8 ft in NW swell, highest N of Punta Eugenia. Inside the Gulf of California, winds are light and variable with seas to 3 ft. Elsewhere across the S and SW Mexican offshore waters, winds are light to gentle, and mostly from the W to NW, with moderate seas 5 to 6 ft in southerly swell.

For the forecast, high pressure well NW of the local area will shift NE throughout the week, and act to weaken the pressure gradient across the Baja California offshore waters. This will lead to winds becoming moderate across the Baja waters by tonight and continuing through Thu, with small areas of locally fresh winds developing near the coasts each afternoon and evening. As the high pressure shifts northeastward, NW winds will increase across the near and offshore waters of California, with fresh NW winds extending southward to the Baja Norte waters NW of Guadalupe Island. Associated NW swell will continue to move into the area offshore waters through the week, with seas in excess of 8 ft persisting across the waters north through west of Punta Eugenia through Thu afternoon. Gentle to moderate winds and moderate seas are expected elsewhere across the Mexican offshore waters through Fri.


...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR...

Light and variable winds prevail across the Central America offshore waters. Seas across the area are 4-6 ft in S swell, except 3-4 ft in the Gulf of Panama. Between the coast of Ecuador and the Galapagos Islands, winds are gentle to moderate from the S to SE with 6 to 7 ft seas in S swell.

For the forecast, S to SE winds south of 05N will become S to SW and increase to moderate to locally fresh speeds from Tue morning through Thu. Light to gentle variable winds will be prevalent elsewhere along with moderate seas in S swell. Otherwise, southerly swell will maintain seas of 5 to 7 ft S of the Galapagos Islands through early Fri, increasing to 6 to 8 ft in S swell Fri afternoon through Sat.


...REMAINDER OF THE AREA...

1030 mb high pressure is centered north of Hawaii near 36N148W and extends a ridge south and southeastward across the subtropical waters, to near the Revillagigedo Islands. Moderate to locally fresh N-NE winds are noted between 115W and 125W, then become NE to E-NE to the west of 125W. Seas across this area N of 20N are 6-8 ft in mixed N and NW swell. S of 20N, between the ridge and the ITCZ and W of 125W, moderate to fresh NE winds and 7-9 ft seas in NE swell prevail. South of the ITCZ, gentle to moderate SE to E winds are noted with 6 to 8 ft seas in mixed swell. Elsewhere, light to gentle variable winds and moderate seas prevail.

For the forecast, moderate to fresh trade winds over the western part of the tropical waters will prevail through Tue afternoon then gradually diminish to moderate speeds through Fri as high pressure to the north shifts northeastward. Seas with these winds will be 6 to 9 ft, and will subside Tue night into Wed. NW swell across the Baja California Norte waters will build through mid week to produce seas of 8 ft and greater mainly N of 25W and E of 130W Wed through Thu night. The seas there will subside below 8 ft late Thu night.
