During severe weather season, it’s important to know how to respond when you hear an outdoor warning siren, also known as a tornado siren. These sirens indicate an urgent risk of tornadoes and dangerous thunderstorms, but many people don’t realize they are primarily designed to alert those who are outdoors—not indoors. In fact, tornado sirens are not meant to be heard indoors.
What to do when you hear a siren while outdoors
According to the National Weather Service, the sirens are an alert to observe conditions around you and seek shelter. When you hear a tornado siren:
- Go indoors and immediately.
- Check the local news, a weather radio, a trusted weather app, or other online sources for updates on the storm.
- Don’t assume the danger has passed when the siren stops. Sirens typically sound for a few minutes, but the threat may persist much longer. Stay inside until local officials confirm it is safe.
Tornado sirens while indoors
Even if you can hear a tornado siren inside during a test, do not rely on them as your sole notification source for severe weather. You might not be able to hear them over common household noises, like a vacuum, television, exhaust fan or running water.
You should always have multiple ways to get warnings. If severe weather is predicted overnight, make sure you have a weather radio or cell phone with audible alerts enabled. To ensure you receive timely warnings, always have multiple alert sources:
- Wireless Emergency Alerts (WEAs): These alerts automatically go to most cell phones for tornado warnings.
- NOAA Weather Radios: These provide continuous updates and can wake you up if a storm strikes overnight.
- Local Alert Systems: Many Kansas City-area counties offer text or email emergency notifications—check with your local emergency management office.
- Weather Apps: Trusted weather apps from local news stations or national meteorological organizations can provide real-time updates.

By staying informed and using multiple warning sources, you can better protect yourself and your loved ones during severe weather.
