Simon is moving \nslowly toward the northwest near 2 mph (4 km/h) and this general \nmotion at a somewhat faster speed is expected to continue into early \nTuesday. A gradual turn toward the northeast is forecast thereafter, \nand Simon is expected to move inland across west-central Mexico \naround midweek.\n \nMaximum sustained winds are near 115 mph (185 km/h) with higher \ngusts. Simon is a category 3 hurricane on the Saffir-Simpson \nHurricane Wind Scale. Some additional weakening is forecast, however \nSimon is expected to remain a hurricane through midweek. Rapid \nweakening is likely after Simon moves inland.\n \nHurricane-force winds extend outward up to 15 miles (30 km) from\nthe center and tropical-storm-force winds extend outward up to 60\nmiles (95 km).\n \nThe estimated minimum central pressure is 958 mb (28.29 inches).\n \n \nHAZARDS AFFECTING LAND\n----------------------\nKey messages for Simon can be found in the Tropical Cyclone\nDiscussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC.\n \nWIND: Hurricane conditions are likely occuring in the Hurricane \nWarning area, with hurricane conditions spreading northward today. \nHurricane conditions are possible within the watch area by \nWednesday, with tropical storm conditions possible by Tuesday night.\n \nRAINFALL: Simon is expected to produce additional rainfall totals of \n2 to 4 inches across coastal portions of southwest and west-central \nMexico with isolated additional amounts of 6 to 8 inches over \nportions of the state of Jalisco into the early portion of the week \nand the state of Sinaloa mainly Wednesday and Thursday. Isolated \nmaximum storm totals of 30 inches are possible over portions of the \nstates of Michoacan, Colima, and Jalisco. This rainfall will produce \nlife-threatening flooding and mudslides or worsen any on-going \nflooding, especially in areas of steep terrain.\n \nFor a complete depiction of forecast rainfall associated with Simon,\nplease see the National Weather Service Storm Total Rainfall Graphic\navailable at hurricanes.gov/graphics_ep5.shtml?rainqpf.\n \nSTORM SURGE: A dangerous storm surge is expected along the immediate\ncoast near and to the east of where the center approaches land. Near\nthe coast, the surge will be accompanied by large and destructive\nwaves.\n \nSURF:  Swells generated by Simon will affect portions of the coast\nof southwestern and west-central Mexico during the next few days.\nThese swells are likely to cause life-threatening surf and rip\ncurrent conditions.
