Reported tornado hits southern Minnesota town of Truman

Severe storms hit southern Minnesota Monday afternoon and evening, prompting thunderstorm and tornado warnings over several hours. Two tornadoes were reported, one near the town of Truman, and the other near Amboy.

Minnesotans will hear two outdoor warning sirens Thursday as part of the annual statewide tornado drill for Severe Weather Awareness week

Statewide tornado drills set for April 16

Local perspective:

The drills are scheduled for 1:45 p.m. and 6:45 p.m. on Thursday, April 16. During both times, the outdoor sirens will sound as part of a simulated tornado warning. The National Oceanic and Atmospheric Administration will also issue a routine test message, and the National Weather Service (NWS) plans to share updates on social media during the test. 

This drill is separate from the routine monthly siren tests, which typically take place on the first Wednesday of each month.

According to the NWS, counties and cities decide when and how to activate the sirens. During severe weather, sirens typically sound for about three minutes and rarely run for the entire weather warning. The reasons for siren activation vary, with some counties only sounding the siren for tornadoes, while others use it for tornadoes and severe thunderstorms with winds at least 70 to 80 mph.

While tornadoes are most common between May and August, they have occurred as early as March and as late as December.
