At least 13 people have died in vehicle crashes and pile-ups during severe dust storms in three states, authorities say as a cross-country storm system sweeping East delivered raging winds and an extreme fire risk.

High winds and dry weather fueled wildfires in Oklahoma and Texas, with winds so strong they toppled several semis.

At a press conference in Mannford Saturday morning, Gov. Kevin Stitt said more than 170 thousand acres had burned and more than 293 homes and structures were destroyed across the state during Friday's destructive wildfire storms.
