As part of Severe Weather Awareness Week in Minnesota, today’s focus is on alerts and warnings—critical tools that help keep people safe when severe weather strikes.
Thanks to modern technology, life-saving information can now reach us almost anywhere. From Wireless Emergency Alerts (WEA) on cell phones to personal weather alert subscriptions, residents are encouraged to explore how they can receive timely updates. These alerts can provide crucial minutes to seek shelter before dangerous weather arrives.
Understanding the different types of alerts is essential. Advisories indicate less severe but still potentially hazardous conditions. Watches suggest that conditions are favorable for severe weather, urging people to stay alert and prepare to act. Warnings mean a dangerous event—such as a tornado, flash flood, or severe thunderstorm—is either happening or imminent, and immediate action is necessary.
Outdoor sirens are one of the most familiar alert methods. However, siren activation policies vary by city and county. Some activate sirens for tornadoes only, while others include severe thunderstorms with high winds. Sirens typically sound for about three minutes, and it’s important to remember there is no “all-clear” siren signal.
Minnesotans are encouraged to learn how local sirens are used, subscribe to weather alerts, and understand how to respond when warnings are issued. Knowing what to do in the moments before severe weather hits can save lives.
