OFFSHORE WATERS WITHIN 250 NM OF MEXICO Please refer to the Special Features section above for details on the Gale Warning for the Gulf of Tehuantepec. Surface ridging continues to prevail W of Baja California. Moderate N winds are noted off of Baja California with seas 3-5 ft. Moderate to fresh winds prevail in the central Gulf of California with seas to 6 ft. Light to gentle winds are observed in the northern Gulf and gentle to moderate winds in the southern Gulf with seas 2-4 ft. Light to gentle winds prevail elsewhere across the offshores of Mexico with seas 3-5 ft. Showers are noted off the coast of Jalisco through Michoacan. For the forecast, gale-force winds will continue across the Gulf of Tehuantepec through Sun night with seas building to 12 ft. Meanwhile, winds will become gentle to moderate across the Gulf of California today. A cold front will move into the northern Gulf of California and off of Baja California Norte on Sat. Fresh to strong winds can be expected in the northern Gulf on Sat morning with seas to 5 ft. The front will stall and dissipate over Baja California Sur and the southern Gulf of California Sun into Mon. Moderate to locally fresh winds can be expected in the Gulf through Sun night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR High pressure N of the area is supporting fresh to strong NE to E gap winds across the Papagayo region extending to near 90W. Seas across that area are 5-6 ft. Moderate to locally fresh northerly winds are in the Gulf of Panama region with seas to 5 ft. Elsewhere, winds are moderate or weaker with seas 3-5 ft. For the forecast, fresh to strong NE to E gap winds will pulse across the Papagayo region through the middle of next week. Winds will pulse moderate to fresh across the Gulf of Panama through early next week. Elsewhere, winds should remain tranquil for the next several days. Large NW to N swell from the Gulf of Tehuantepec will impact the Guatemala and El Salvador offshore waters Sat night through Sun night. REMAINDER OF THE AREA A 1006 mb low is near 23N139W which is a little more than 1000 miles east-northeast of Hilo, Hawaii. Strong winds are noted north of the low with seas 12 to 17 ft. Showers and thunderstorms around this low have decreased and become less organized, and is noted east of the low from 13N to 25N between 126W and 133W. This system is expected to move westward into increasingly unfavorable environmental conditions during the next day or so, and development into a subtropical or tropical cyclone is unlikely. This low has a low chance of development in the next 48 hours and 5 days. For the forecast, high pressure building N of the 1006 mb low pressure will continue to support a large area of fresh to strong E winds today. As the low moves west of 140W later today, it will substantially weaken. Winds and seas are expected to diminish this afternoon through tonight. $$ Ramos
