Scattered twisters and storm damage led to the deaths of at least 13 people in Missouri, including a 30-year-old man who along with his dog was found dead from carbon monoxide poisoning after he was using a generator indoors during the storm, authorities said. In Arkansas, officials confirmed three deaths.

Oklahoma Gov. Kevin Stitt said one person died in Oklahoma after driving into smoke caused by the storms, adding wildfires have burned more than 170,000 acres and have destroyed more than 290 homes.
