The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...SPECIAL FEATURES... Hurricane Rick is centered near 16.1N 101.7W at 24/1500 UTC moving N at 5 kt. Estimated minimum central pressure is 980 mb. Maximum sustained wind speed is 75 kt with gusts to 90 kt. Numerous moderate to strong convection is noted within 120 nm of the center. Rick is forecast to strengthen, and could become a major hurricane before landfall late tonight. A N to NNW motion is expected through landfall in Guerrero or Michoacan, with some increase in forward speed possible. Life-threatening storm surge and dangerous hurricane force winds are possible between Tecpan de Galeana and Punta San Telmo. Near the coast, the surge will be accompanied by large and destructive waves. Swells generated by Rick are affecting portions of the southwestern coast. These swells are likely to cause life- threatening surf and rip current conditions. Please consult products from your local weather office. Rick is expected to produce 8 to 15 inches of rain with isolated storm total amounts in excess of 20 inches across mainly coastal sections of the Mexican states of Guerrero and Michoacan through Tue. This heavy rainfall will likely produce flash flooding and mudslides.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section for more details on Hurricane Rick. Fresh NW winds are ongoing offshore Baja California, with mainly gentle to moderate N to NW winds elsewhere. Seas of 8 to 10 ft persist off Baja California as well in NW swell. Light to gentle winds prevail in the Gulf of California. Mixed swell is likely between Cabo San Lucas, Socorro Island and Cabo Corrientes with components of the NW swell entering the area along with swell generated from Rick farther south. For the forecast, NW swell will continue to move through the offshore waters off Baja California, and will reach the Revillagigedo Islands late today. Looking ahead, another round of NW swell move into Baja California Norte offshore waters Mon, continue south, reaching Socorro Island Tue, then will subside through Thu. Strong westerly gap winds are possible ahead of a cold front over the northern Gulf of California Mon night. Fresh NW winds may follow this front Tue night to the W of Baja California. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Gentle to moderate S to SW winds are occurring S of the monsoon trough with mainly light and variable winds to the north. Seas are 4 to 6 ft, except 5 to 7 ft offshore Ecuador. Mainly gentle to moderate SW winds persist over the Central American offshore waters. Seas will build slightly across the region in SW swell, then will diminish into mid week. REMAINDER OF THE AREA... A trough and low pressure that had been over northern parts of the area has dissipated. A large area of long period NW swell is moving through the region, with seas of 8 to 11 ft most areas N of 10N. The swell subside below 8 ft through Mon. Another reinforcing group of large NW swell is starting to enter the basintoday, and seas will likely rise over 12 ft N of 15N and W of 120W into midweek. $$ KONARIK
