The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0900 UTC. ...TROPICAL WAVES... The axis of a tropical wave is near 102W/103W north of 03N, moving west at around 10 kt. Convection is limited near the wave axis. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough extends from 10N85W to 09N100W to 13N110W to 12N120W to a 1009 mb low pres near 13N130W to 10N140W.

The National Hurricane Center has issued the last advisory on Roslyn, which has dissipated over east-central Mexico. Lingering heavy rainfall from the remnants of Roslyn could lead to flash flooding and possible landslides in areas of rugged terrain over coastal west-central Mexico. A dissipating cold front extends across the central Gulf of California to near 25N118W then continues westward as a shearline to 24N140W. Moderate NW to N winds follow the front with seas of 8-11 in NW swell across the offshore waters of Baja California. In the Gulf of California, fresh to locally strong W to NW winds are noted per scatterometer data in the wake of the front with seas of 4-6 ft. Elsewhere along the coast of Mexico light to gentle westerly winds prevail with seas of 4-6 ft in SW swell. For the forecast, the front will dissipate in about 12-24 hours. Then, a ridge will dominate the offshore forecast waters of Baja California during the next several days producing mainly gentle to moderate NW to N winds. Seas of 8 to 10 ft will continue to propagate across the waters N of Punta Eugenia today and will subside below 8 ft late tonight into Tue. In the Gulf of California, fresh to strong northerly winds in the wake of the front will persist through this evening, with seas building to 5 or 6 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Light to gentle winds prevail N of the monsoon trough with gentle to moderate southerly winds S of the monsoon trough. Seas are 5-7 ft in SW swell. For the forecast, winds will pulse to moderate in offshore southern Nicaragua and the Gulf of Papagayo through Tue. Light to gentle winds will prevail north of the monsoon while moderate to occasionally fresh S-SW winds will prevail south of the monsoon trough through midweek. Seas of 4-6 ft in SW swell will dominate most of the offshore forecast waters. Additional pulses of long period SW swell will reach the waters between Ecuador and the Galapagos Islands by Tue. REMAINDER OF THE AREA... As previously mentioned, a dissipating cold front extends across the central Gulf of California to near 25N118W then continues westward as a shearline to 24N140W.. Fresh to strong NE winds are noted N of the front and W of 130W with seas of 8 to 10 ft. Elsewhere N of the front fresh northerly winds are observed with seas of 8-11 ft in NW swell, highest N of 28N between 118W and 125W. High pressure follows the front and dominates the remainder of the northern forecast waters. For the forecast, the front will dissipate in about 12-24 hours while moving farther S. Seas of 8-11 ft in northerly swell in the wake of the front will gradually subside below 8 ft through Tue. High pressure will dominate the waters N of the monsoon trough and W of 110W over the next several days. Seas of 8-9 ft will reach again the NE waters by Wed. $$ GR
