TYLERTOWN, Miss. (AP) — Unusually vicious and damaging weather across multiple U.S. states spawned violent tornadoes, blinding dust storms and fast-moving wildfires over the weekend, leaving at least 39 people dead.

In the latest tally of the destruction, the Oklahoma Department of Emergency Management said Sunday evening that more than 400 homes were damaged as wildfires swept across the state Friday. At least 74 homes in and around Stillwater were destroyed by wildfires, Mayor Will Joyce said Sunday night on Facebook.

The emergency management department also said the Oklahoma Office of the Chief Medical Examiner confirmed four fatalities related to the fires or high winds.
