Gales are forecast to continue through Sat morning, before diminishing to near gale Sat afternoon and to fresh to strong Sun.

Please read the latest High Seas Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough extends from the Panama/Colombia border near 07N78W to 04N83W to 05N100W. The ITCZ extends from 04N104W to 05N114W to 05N135W to 06N140W. Scattered moderate to isolated strong convection is present from 01S to 08N between 77W and 118W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO Please see the Special Features section above for details about a Gale Warning in the Gulf of Tehuantepec. Gentle NW winds are in the Gulf of California with seas of 1 to 2 ft. ASCAT shows moderate NW to N winds to the west of Baja California, where seas are likely 5 to 6 ft. Elsewhere offshore Mexico, mainly light to gentle variable winds are occurring, with 4 to 5 ft seas. For the forecast, fresh to strong southerly winds will develop in the northern Gulf of California Sun night through Mon night ahead of a cold front. The front will bring in a large set of NW swell to the waters west of Baja California early next week. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR ASCAT overnight showed fresh E winds offshore the Papagayo region east of 88W. Moderate to fresh N winds are likely occurring in the Gulf of Panama, north of 05N. Gentle winds prevail elsewhere. Seas are averaging 4-6 ft, except offshore Guatemala, where 6-8 ft seas prevail in W to NW swell, due to a Gulf of Tehuantepec gap wind event. For the forecast, winds in the Papagayo region will continue to pulse to fresh to strong through early next week. Winds in the Gulf of Panama will pulse to fresh to locally strong Sat night. Elsewhere, winds are forecast to be moderate or weaker into early next week. W to NW swell from an ongoing Gulf of Tehuantepec gap wind event will continue impacting the Guatemala offshore zone today through Sat. REMAINDER OF THE AREA A 1023 mb high pressure is centered near 33N130W, just north of our forecast area. The pressure gradient between the subtropical ridge and lower pressures in the deep tropics is causing moderate to locally fresh trades, primarily from 07N to 17N and W of 127W. Seas in the area described are 7-8 ft. Elsewhere, moderate or weaker winds and 5-7 ft seas prevail. For the forecast, the high pressure north of our area is forecast to continue to weaken through tonight, allowing the trades to diminish. Gentle to moderate winds will prevail over most of the Pacific waters through the weekend. A robust extratropical low is expected to move eastward while centered well north of our 30N border this weekend, dragging an attendant cold front across the northern waters. This system is forecast to bring fresh to strong winds and building seas north of 25N west of 120W Sat night through Mon night, spreading east through early next week. Seas are forecast to peak at 12-18 ft Sun night through Mon. Northerly swell from this system will propagate southward across the area, reaching 10N by Tue night. $$ Hagen
