SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Punta Maldonado to Tecpan De Galeana A Tropical Storm Warning means that tropical storm conditions are expected within the warning area. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the center of Tropical Storm Carlotta was located near latitude 16.8 North, longitude 100.5 West. Carlotta is now moving toward the west-northwest near 10 mph (17 km/h), and this general motion is expected to continue on Sunday. On the forecast track, the small core of Carlotta should move inland within the warning area on Sunday. The circulation of Carlotta has been interacting with land, and surface observations from Mexico and satellite data indicate that the maximum sustained winds have decreased to near 50 mph (85 km/h) with higher gusts. Gradual weakening is anticipated and the small cyclone could dissipate at a faster rate if the entire circulation moves over the high terrain of Mexico by Sunday night. Tropical-storm-force winds are confined to a very small area near the center, and extend outward up to 35 miles (55 km) to the east and south of the center. Acapulco reported a wind gusts of 45 mph (74 km/h) a couple of hours ago when the center of Carlotta moved nearby. Since then, winds have begun to rapidly decrease. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Carlotta is forecast to produce 3 to 6 inches of rainfall along the Guerrero and southwestern Oaxaca coasts, including the city of Acapulco, with isolated higher amounts of 10 inches possible. These rains are likely to produce life-threatening flash floods and mudslides, especially in areas of higher terrain. Elsewhere across the states of Guerrero and Oaxaca, rainfall amounts of 1 to 2 inches with isolated amounts of 4 inches are forecast. WIND: Tropical storm conditions are likely occurring in the warning area, and these conditions are expected to continue into Sunday. SURF: Swells generated by Carlotta are affecting portions of the coast of southern Mexico. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Avila
