The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0915 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from coastal sections of Costa Rica near 09N85W to a 1008 mb low pressure center near 10N101W to a 1008 mb low pressure center near 09N115W to 08N123W. The ITCZ continues from 08N123W to beyond 09N140W. Scattered moderate convection is N of 07N between 88W and 97W, and from 06N to 10N between 104W and 110W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Surface ridging will prevail across the offshore waters through Friday. The ridge is forecast to support light to gentle NW winds west of Baja California through Monday afternoon. NW swell in excess of 8 feet will move southward across the Baja California Norte offshore waters starting Monday night and prevailing through Wednesday night. Moderate NW winds are expected during this period in the waters of Baja California Norte as the pressure gradient tightens between the ridge and a surface trough that will develop between the peninsula and the Gulf of California. Gulf of Tehuantepec...Fresh to strong gap winds will prevail in the gulf through Tue morning due to strong high pressure over the Gulf of Mexico. Seas are forecast to build up to 10 feet during this period. The ridge will shift ENE afterwards, thus resulting in the end of the gap wind event. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gulf of Papagayo...Moderate to fresh NE winds will prevail across and downstream of the gulf through Wednesday with seas building to 7 ft. Gentle to moderate SW winds will increase to fresh to strong over a portion of the Colombian offshore waters Sun afternoon. Seas in this region are expected to build to 7 ft. Winds will decrease to moderate to fresh off Colombia by Sunday night. Light to gentle variable winds will prevail elsewhere with 4-6 ft seas. REMAINDER OF THE AREA... The pressure gradient between a ridge north of 15N and the ITCZ, is supporting a swath of fresh trade winds from 15N to 22N west of 138W with seas to 8 feet. NW swell associated with a weak cold front N of the area will move across the NW waters today through Monday, reaching Baja California Norte through the middle of the week. Sea heights will be in the range of 8 to 11 feet. A 1008 mb low pressure center is near 10N101W supporting scattered heavy showers and tstms within 210 nm west semicircle and 90 nm east semicircle. The low will track westward the next several days along with fresh to strong winds and associated seas. There is a medium chance for this system to become a tropical cyclone during the next five days. A second 1008 mb low pressure center is centered near 09N115W. The low will track westward with seas to 8 ft in southwest swell. There is a low chance of tropical cyclone development associated with this low. $$ Ramos
