These storms brought close to two feet of new snow over the Western Mogollon Rim at 7000 feet and close to four feet of new snow above 9000 feet. The first storm was cold enough to lower the snow level to the floor of the Grand Canyon. The snow level rose to the 7000 foot level for an hour or two with the second storm. Dring this event the Department of Public Safety for northern Arizona responded to 188 slideoffs on highways in the northern region.
