Based on 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends southwestward from 08N83W to 04N93W. An ITCZ extends westward from 04N93W to 02N115W to 03N137W. A second ITCZ reaches west-southwestward from 01S86W to 04S105W to beyond 03S120W. Scattered moderate to isolated strong convection is noted from 04N to 09N between 83W and 90W, and within 55 nm of 05S89W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... The pressure gradient between high pressure west of the area and a trough over the Gulf of California is supporting moderate to fresh NW to winds west of Baja California, with moderate winds extending southward to near the Revillagigedo Islands and off Cabo Corrientes. Gentle to moderate S to WSW winds exist in the Gulf of California. Light to gentle winds are seen across the offshore waters of southern Mexico. Moderate seas prevail across the open waters off Mexico, with slight seas over the Gulf of California. For the forecast, fresh to locally strong NW winds offshore Baja California will become gentle to moderate this weekend, then increase to between moderate and fresh by Mon. NW swell will also bring locally rough seas off Baja California Norte through Sat evening. Fresh NW to N winds will pulse in the northern Gulf of California today through Sat morning. In the long term, strong to near gale-force N gap winds along with rough seas are expected in the Gulf of Tehuantepec Sun night through midweek next week. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh NE to E gap winds prevail over and downstream the Papagayo region. Winds are light to gentle elsewhere.

A trough of Low pressure cuts across the northwestern corner of the discussion area from 30N135W to 25N140W. Fresh to locally strong winds are found near the trough of low pressure. The pressure gradient between the surface ridge and lower pressure in the vicinity of the ITCZ is supporting gentle to moderate winds elsewhere north of the ITCZ. Light to gentle winds prevail south of the ITCZ. Moderate to rough seas in cross equatorial swell prevail south of 10N and west of 94W. For the forecast, the pressure gradient between the aforementioned ridge and low pressure will support fresh with locally strong E to SE winds N of 20N and W of 127W today, then become gentle to moderate by tonight. Lingering NW swell should maintain rough seas north of 28N through Sat, then become moderate. Moderate ENE to E winds with moderate seas in persistent S swell should continue from the ITCZ to 20N through Tue. A new set of NW swell associated with a cold front is going to bring back rough seas near 29N138W for Tue.
