MTSU Testing Tornado Sirens Mar 01, 2021 at 11:31 am by WGNS MTSU will continue its “first Monday” tornado–siren testing schedule for the 2020-21 academic. In fact, you may have heard tornado sirens on Monday morning at 11:20am (March 1, 2021). MTSU tests its tornado sirens on campus and at the Miller Coliseum Complex each month, weather permitting, to ensure their proper operation. Each test lasts only a few moments, and safety actions aren’t required. Again, tests were conducted on Monday morning at 11:20 (March 1, 2021). The monthly day and time were chosen to help reduce distractions for classes and community neighbors. The university will continue to notify the campus community before these monthly tests via social media, emails and posts at MTSUNews.com.
