Several states, including West Virginia, Kentucky, Michigan, Washington, Oregon, Tennessee, Louisiana, and Arkansas, have been affected by severe weather, prompting an emergency declaration approved by Trump. The declaration is expected to provide disaster aid, with some reports specifying that at least $32.1 million has been allocated for damage in Michigan. The total number of states impacted and the full scope of the disaster aid are not entirely clear, with reports varying on the number of states and the specific types of weather events involved.
