On the forecast track, Simon is expected to be near or just \ninland over west-central Mexico later today and move very close to \nthe coast on Monday.\n \nMaximum sustained winds are near 155 mph (250 km/h) with higher\ngusts.  Simon is a category 4 hurricane on the Saffir-Simpson\nHurricane Wind Scale.  While some slight weakening could occur, \nSimon is still forecast to move near or over the coast of \nwest-central Mexico as a major hurricane today. Rapid weakening \ncould occur if the core of Simon moves fully onshore.\n \nHurricane-force winds extend outward up to 25 miles (35 km) from the\ncenter and tropical-storm-force winds extend outward up to 90 miles\n(150 km).\n \nThe estimated minimum central pressure is 930 mb (27.47 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 expected in the southern part of the\nHurricane Warning area beginning soon, with tropical storm\nconditions spreading northward today. Tropical storm conditions \nare possible within the Tropical Storm Watch area within the next\nseveral hours.\n \nRAINFALL: Simon is expected to produce additional rainfall totals of \n10 to 20 inches over portions of southwestern Mexico, with isolated \nmaximum totals of 30 inches possible across portions of Michoacan, \nColima, and Jalisco through Monday.  This rainfall will produce \nlife-threatening flooding and mudslides, especially in areas of \nsteep 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 makes landfall. 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.
