The followinginformation is based on satellite imagery, weather observations,radar, and meteorological analysis.Based on 1800 UTC surface analysis and satellite imagery through1900 UTC....INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...A trough axis extends from 09N82W to 10N90W to 09N97W. The ITCZ extends from 09N97W to 09N119W to beyond 08N140W. Scattered moderate convection is active within 90 nm N of the ITCZ between105W and 132W....OFFSHORE WATERS WITHIN 250 NM OF MEXICO...Ridging off Baja California combined with troughing over northwestMexico supports moderate to fresh winds off the peninsula.Moderate NW winds have also developed over the southern Gulf ofCalifornia. Winds are light to gentle elsewhere. Combined seas are 5-7 ft off Baja California, 3-5 ft off southwest and southernMexico, and 1-3 ft in the Gulf of California.For the forecast, ridging will build over the area through late week. The pattern will support fresh northwest winds over the Baja California waters as well as the central and southern Gulfof California. Winds will pulse to strong offshore BajaCalifornia S of Punta Eugenia and in the central and southernGulf of California Thu. Looking ahead, strong to near gale forcegap winds will develop Sat night across the Gulf of Tehuantepec.....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR...Light to gentle variable winds and 3-6 ft combined seas prevail north of the Equator, except for moderate gap winds in the Papagayo region and in the Gulf of Panama. Gentle to moderate E winds prevail south of the Equator, within 5-7 ft seas in S to SWswell.For the forecast, a weak pressure gradient will maintain rather tranquil conditions over the Central American and Colombian waters through the week while moderate to fresh southeast winds and moderate long-period south to southwest swell remain offshoreEcuador. Seas will subside slightly by the end of the week into the weekend. Winds will pulse to moderate to fresh in the Gulf ofPapagayo and Gulf of Panama nightly through Thu. ...REMAINDER OF THE AREA...Moderate to fresh NE winds and seas of 5 to 7 ft dominate watersN of the ITCZ due to the gradient between the ITCZ and highpressure centered in the North Pacific. Mainly gentle winds arenoted S of the ITCZ. Seas are 6 to 8 ft in mixed SE and NW swellS of the Equator, and 4 to 7 ft elsewhere S of the ITCZ.For the forecast, little change is expected into the weekend.Moderate to fresh NE winds and moderate seas will prevail N ofthe ITCZ, with gentle winds and moderate seas to the S. $$Konarik
