DISCUSSION AND OUTLOOK ---------------------- At 1000 AM CDT (1500 UTC), the center of Hurricane Agatha was located near latitude 15.3 North, longitude 97.1 West. Agatha is moving toward the northeast near 8 mph (13 km/h) and this general motion is expected to continue through Tuesday. On the forecast track, the center of Agatha will make landfall in the state of Oaxaca, Mexico, this afternoon or this evening. Maximum sustained winds are near 110 mph (175 km/h) with higher gusts. Little change in strength is expected today before Agatha reaches the coast of Oaxaca. Rapid weakening is expected after landfall, and Agatha is forecast to dissipate over southeastern Mexico by late Tuesday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km). An observation in Puerto Angel recently reported a wind gust of 40 mph (65 km/h). The estimated minimum central pressure is 964 mb (28.47 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in the hurricane warning area and possible in the watch area by this afternoon. Tropical storm conditions have begun along the coast of Oaxaca and will spread eastward within the warning area through the day. STORM SURGE: Storm surge is expected to produce extremely dangerous coastal flooding in areas of onshore winds near and to the east of where the center of Agatha makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Agatha will produce heavy rains over portions of southern Mexico through Tuesday night. The following rainfall amounts are currently expected: Mexican state of Oaxaca: 10 to 16 inches, with isolated maximum amounts of 20 inches possible. Life-threatening flash flooding and mudslides may occur. Mexican state of Chiapas: 5 to 10 inches, with isolated maximum amounts of 15 inches possible. Life-threatening flash flooding and mudslides may occur. Mexican states of Veracruz, Tabasco and eastern portions of Guerrero: 2 to 4 inches, with isolated maximum amounts of 6 inches possible. SURF: Large swells generated by Agatha will affect the coast of southern Mexico during the next day or two. These swells are likely to cause life-threatening surf and rip current conditions.
