The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0830 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 08N83W to 05N107W. The ITCZ continues from 05N107W to beyond 04N140W. Scattered moderate isolated strong convection is noted from 02N to 10N between 87W and 103W, and from 05N to 10N between 113W and 120W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Gentle to moderate winds prevail over the waters west of the Baja California peninsula as well as west of Cabo Corrientes. Gentle to moderate winds are also over the Gulf of California. Light to gentle winds prevail elsewhere. NW swell is bringing seas of 6-8 ft over the waters west of the Baja California peninsula. Seas of 1-3 ft are over the Gulf of California. Elsewhere, seas of 4-5 ft prevail. Areas of smoke from agricultural fires may persist over offshore waters southeast of Cabo Corrientes to the Guatemala border. For the forecast, fresh SW gap winds over the northern Gulf of California will increase tonight to strong to near gale force before diminishing Thu. Winds will freshen west of Baja California this weekend. ...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Moderate to fresh winds are found over the Gulf of Papagayo. Light to gentle winds prevail elsewhere. Seas are in the 4-5 ft range north of the equator, and 5-7 ft south of the equator. Otherwise, low visibility due to agricultural fires is likely from the Guatemala to Nicaragua offshore waters. For the forecast, high pressure building well north of the area will support pulses of fresh to strong gap winds across the Gulf of Papagayo and the coast of Nicaragua mainly at night beginning tonight and lasting through the weekend. Gentle to moderate breezes will prevail elsewhere through late week. Southerly swell will increase in the waters between Ecuador and the Galapagos Islands tonight through Thu night before subsiding Fri. ...REMAINDER OF THE AREA... High pressure prevails across the waters north of 20N. The pressure gradient between this area of high pressure and lower pressure in the vicinity of the ITCZ is supporting moderate to fresh winds north of the ITCZ to 25N and west of 120W. Gentle to moderate winds are found elsewhere north of the ITCZ. Light to gentle winds are noted south of the ITCZ. Combined seas of 7 to 9 ft are moving through most of the region north of 20N, except over the area near 30N140W, where seas are 6 to 7 ft. Seas of 6-8 ft are found south of 20N and west of 130W. Seas in the 4 to 7 ft are noted elsewhere north of the Equator. South of the Equator to 3.4S, seas are in the 6 to 8 ft range in S swell. For the forecast, NW to N swell north of 18N will propagate into the deep tropics by late today, reinforcing the seas west of 115W. Winds and seas will diminish north of 20N Thu as high pressure builds farther north of the area. This pattern will support moderate to fresh trade winds and 6 to 9 ft seas over the tropical Pacific west of 115W. A weak cold front will move into the waters north of 20N and west of 120W Fri into Sat. $$ AL
