Simon is moving\ntoward the north near 5 mph (7 km/h) and this general motion is\nexpected to continue over the next day or two. On the forecast\ntrack, Simon is expected to be near or just inland over west-central\nMexico on Sunday.\n \nMaximum sustained winds have increased to near 155 mph (250 km/h)\nwith higher gusts. Simon is a category 4 hurricane on the\nSaffir-Simpson Hurricane Wind Scale. Fluctuations in intensity are\nanticipated, but Simon is still forecast to approach the coast of\nwest-central Mexico as a major hurricane on Sunday. 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 928 mb (27.41 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 early Sunday, with tropical storm\nconditions expected as soon as later tonight with these winds\nspreading northward thereafter. Tropical storm conditions are\npossible within the Tropical Storm Watch area beginning tonight.\n \nRAINFALL: Simon is expected to produce rainfall totals of 10 to 20\ninches over portions of southwestern Mexico, with isolated maximum\ntotals of 30 inches possible across portions of Michoacan, Colima,\nand Jalisco through Sunday. 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.
