On October 5–6, 2010, a destructive series of thunderstorms struck Arizona, resulting in the state's largest tornado outbreak and its costliest weather disaster on record. Spawned by a nearby cold-core low, successive hailstorms in Phoenix and surrounding locations on October 5 caused damage to thousands of homes, businesses, and vehicles. The following day, a record 12 tornadoes were recorded, multiple strong/EF2 or greater on the Enhanced Fujita scale and many in close proximity to one another; this included two tornadoes rated EF3. Thunderstorms on both days caused significant flash flooding which inundated businesses, stranded vehicles, and closed roadways. Damage throughout the state reached $4.9 billion, including $2.7 billion in insured loss from just hail damage, the costliest weather event on record in Arizona. Some impacts occurred in California, Nevada, and Utah as well as the cold-core remained stationary over several days.
