Simon is moving toward the north near \n5 mph (7 km/h), and this general motion is expected to continue \nover the next day or two. On the forecast track, Simon is expected \nto be near or just inland over west-central Mexico later today.\n \nMaximum sustained winds remain near 155 mph (250 km/h) with higher\ngusts.  Simon is a category 4 hurricane on the Saffir-Simpson\nHurricane Wind Scale.  Fluctuations in intensity are anticipated, \nbut Simon is still forecast to approach the coast of west-central \nMexico as a major hurricane later today. Rapid weakening could \noccur if the core of Simon moves fully onshore.\n \nHurricane-force winds extend outward up to 25 miles (35 km) from\nthe center and tropical-storm-force winds extend outward up to 90\nmiles (150 km).\n \nThe estimated minimum central pressure is 928 mb (27.41 inches) \nbased on Air Force dropsonde data.\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 today, 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 in the next \nfew hours.\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 today. 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.
