Simon is moving\nslowly toward the west-northwest near 3 mph (6 km/h), but is\nforecast to resume a slow northwestward motion by tonight which\nshould then continue into early Tuesday. A gradual turn toward the\nnortheast is forecast thereafter. On the forecast track, Simon is\nexpected to be near Las Islas Marias tonight into Tuesday, and then\napproaching the west-central Mexico coastline on Wednesday into\nThursday.\n \nMaximum sustained winds have decreased to near 100 mph (155 km/h)\nwith higher gusts. Additional weakening is forecast over the next\nday or so, but Simon could re-intensify some by Wednesday and is\nforecasted 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 10 miles (20 km) from the\ncenter and tropical-storm-force winds extend outward up to 45 miles\n(75 km).\n \nThe estimated minimum central pressure is 969 mb (28.62 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. \nHurricane conditions are possible within the watch area on \nWednesday, with tropical storm conditions possible by Tuesday night.\n \nRAINFALL: Simon is expected to produce rainfall totals of 5 to 10\ninches across coastal west-central Mexico with isolated maximum\namounts of 15 inches over the state of Sinaloa by Thursday.\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 immediate\ncoast near Las Islas Marias.
