DISCUSSION AND OUTLOOK ---------------------- At 1100 AM MST (1800 UTC), the center of Hurricane Simon was located near latitude 20.2 North, longitude 106.6 West. Simon is drifting toward the west near 2 mph (4 km/h), but is forecast to resume a slow northwestward motion by tonight which should then continue into early Tuesday. A gradual turn toward the northeast is forecast thereafter, and Simon is expected to approach the west-central Mexico coastline on Wednesday into Thursday. Maximum sustained winds have decreased to near 105 mph (165 km/h) with higher gusts. Some additional weakening is forecast today, but Simon could re-intensify some on Tuesday and Wednesday and is expected to remain a hurricane through midweek. Rapid weakening is likely after Simon moves inland late this week. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 60 miles (95 km). The estimated minimum central pressure is 965 mb (28.50 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Simon can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC. WIND: Hurricane conditions are likely to occur in the Hurricane Warning area of Las Islas Marias beginning tonight into Tuesday. Tropical storm conditions are expected to occur for a few more hours in the Tropical Storm warning area. Hurricane conditions are possible within the watch area by Wednesday, with tropical storm conditions possible by Tuesday night. RAINFALL: Simon is expected to produce additional rainfall totals of 2 to 4 inches across coastal portions of southwest and west-central Mexico with isolated additional amounts of 6 to 8 inches over portions of the state of Jalisco through early this week, and the state of Sinaloa mainly Wednesday and Thursday. Isolated maximum storm totals of 30 inches are possible over portions of the states of Michoacan, Colima, and Jalisco. This rainfall will produce life-threatening flooding and mudslides or worsen any on-going flooding, especially in areas of steep terrain. For a complete depiction of forecast rainfall associated with Simon, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_ep5.shtml?rainqpf. STORM SURGE: A dangerous storm surge is likely along the immediate coast near Las Islas Marias. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Simon will affect portions of the coast of southwestern and west-central Mexico during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
