Overview
- A fast-moving convective system the National Weather Service’s Storm Prediction Center preliminarily classified as a derecho swept from Iowa into Indiana, producing hurricane‑force straight‑line winds and multiple confirmed tornadoes.
- The storms caused multiple deaths and serious injuries, including a person killed in a Portage, Indiana, house explosion and a 4‑year‑old killed when a tree toppled onto a home.
- Downed trees and power lines overturned vehicles, ripped roofs and blocked roads, producing record outages for some utilities and leaving hundreds of thousands to more than one million customers without electricity at the peak.
- State and local officials mobilized emergency resources, with governors preparing declarations, National Guard units deployed, mutual‑aid utility crews summoned, and crews conducting water rescues in flood‑hit communities.
- Heavy, repeated rainfall has produced flash‑flood emergencies in parts of Indiana and Ohio and forecasters warn additional rounds of severe storms and localized heavy rain could extend flood and wind risks over the next few days.
