For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Tropical Storm Carlotta was located near latitude 17.0 North, longitude 100.7 West. Carlotta is moving toward the northwest near 7 mph (11 km/h), and this general motion is expected to continue today. On the forecast track, the small core of Carlotta should move inland within the warning area later today or early Monday. However, any deviation to the right of the track could result in an earlier landfall. 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 today or Monday. Carlotta is a very small cyclone, and the tropical-storm-force winds extend outward up to 35 miles (55 km) mainly to the east and south of the center. 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, southwestern Oaxaca, and southern Michoacan 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 to spread westward along the warning area. 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.
