Simon is drifting \ntoward the west near 2 mph (4 km/h), but is forecast to resume a \nslow northwestward motion by tonight which should then continue \ninto early Tuesday. A gradual turn toward the northeast is forecast \nthereafter, and Simon is expected to approach the west-central \nMexico coastline on Wednesday into Thursday.\n \nMaximum sustained winds have decreased to near 105 mph (165 km/h) \nwith higher gusts. Some additional weakening is forecast today, but \nSimon could re-intensify some on Tuesday and Wednesday and is \nexpected to remain a hurricane through midweek. Rapid weakening is \nlikely after Simon moves inland late this week.\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 965 mb (28.50 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 to occur in the Hurricane \nWarning area of Las Islas Marias beginning tonight into Tuesday. \nTropical storm conditions are expected to occur for a few more hours \nin the Tropical Storm warning area. Hurricane conditions are \npossible within the watch area by Wednesday, with tropical storm \nconditions 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 through early this week, and the\nstate of Sinaloa mainly Wednesday and Thursday. Isolated maximum\nstorm totals of 30 inches are possible over portions of the states\nof 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 likely along the immediate \ncoast near Las Islas Marias. Near the coast, the surge will be \naccompanied by large and destructive 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.
