NWS Outage Delays Warnings Amid Deadly Midwest Storms
US · Published Aug 13, 2026
A software glitch disrupted the National Weather Service's (NWS) ability to issue timely severe weather warnings during a series of deadly thunderstorms across the Midwest and Ohio Valley on Tuesday evening.
The outage, which lasted from 6 p.m.

Impact & Risks

The delayed warnings posed significant risks to residents in the affected areas, as severe weather events like tornadoes and flash floods require immediate action to ensure safety. In some cases, warnings were delayed by over 20 minutes, which is critical given that the average lead time for tornado warnings is just 13 minutes. The outage highlighted vulnerabilities in the NWS's aging IT infrastructure, which is not expected to be fully modernized until 2028. The incident underscores the importance of having multiple ways to receive weather alerts, as delays in communication can lead to increased risks of injury, property damage, and loss of life.
