The US Midwest and Ohio Valley, including Chicago and Cincinnati, face an enhanced, or level 3, risk of severe thunderstorms. The National Weather Service has issued a warning that covers a broad area, highlighting the potential for intense rainfall and strong winds.

The storm system is expected to bring heavy rain, hail, and gusty winds that could trigger flash flooding, especially in low‑lying neighborhoods and along river corridors. The level 3 designation signals that the weather can be severe enough to cause significant damage.

Residents are urged to stay informed via local media, check updates on the official NOAA website, and keep emergency supplies ready. Avoid driving through flooded roads and keep pets indoors until the risk subsides.

The warning remains in effect through 11:00 PM local time, after which the National Weather Service will reassess the threat. People should remain vigilant and follow official guidance to stay safe.
