Simon is moving\ntoward the northwest near 5 mph (7 km/h).  A turn to the north is \nforecast Saturday morning.  On the forecast track, the core of \nSimon is expected to approach the coast of southwestern and\nwest-central Mexico on Saturday.\n \nMaximum sustained winds have quickly increased to near 90 mph (150 \nkm/h) with higher gusts.  Rapid intensification is expected to \ncontinue, and Simon is expected to be a very dangerous major \nhurricane when it approaches the coast of Mexico.\n \nHurricane-force winds extend outward up to 15 miles (30 km) from the\ncenter and tropical-storm-force winds extend outward up to 80 miles\n(130 km).\n \nThe estimated minimum central pressure is 978 mb (28.88 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 warning area\nSaturday evening or Sunday, with tropical storm conditions expected \nSaturday morning.  Tropical storm conditions are possible within \nthe Tropical Storm Watch area beginning tonight or early Saturday.\n \nRAINFALL: Simon is expected to produce rainfall totals of 8 to 15 \ninches over portions of southwestern Mexico, with isolated maximum \ntotals of 25 inches possible across portions of Michoacan, Colima, \nJalisco and Nayarit through Sunday.  This rainfall may 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 possible along the\nimmediate coast near and to the east of where the center makes\nlandfall. Near the coast, the surge will be accompanied by large and\ndestructive waves.\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.
