Statewide tornado drills to sound sirens twice April 16
Minnesotans should expect statewide tornado sirens to be tested twice on Thursday, April 16, as part of Severe Weather Awareness Week. The tests will sound across the state in the afternoon and again in the evening — 1:45 p.m. and 6:45 p.m., according to local meteorologists — and officials say the purpose is to exercise warning systems and make sure households, schools and workplaces have an active severe-weather plan in place.
The drills come against a backdrop of costly and sometimes deadly weather in the region: Minnesota has recorded 62 weather and climate disaster events since 1980 with losses exceeding $1 billion, and while the state had 56 tornadoes in 2025 with no related deaths, tornadoes produced about $1.7 billion in damage nationally in 2024. Researchers caution that there is not yet a clear, climate-driven trend in tornado frequency in Minnesota, although improved detection technology has changed how storms are reported and tracked. Improvements in warning performance matter: reductions in the national tornado false-alarm ratio have been associated with a 4%–11% drop in fatalities and a 4%–13% drop in injuries, underlining why drills and clearer messaging can save lives.
Public reaction reflects both support for preparedness and some surprise at the tests. Meteorologists on social media urged people to use the drill to review plans for home, school and work and flagged the exact siren times; a mayor encouraged residents to think proactively about what they would do in a real event. Others said the unexpected soundings are startling if you aren’t aware the drill is coming, and some citizens are questioning whether current alert levels — such as a "Tornado Warning" versus a "Tornado Emergency" — are sufficient for the most dangerous situations. Mainstream coverage has shifted from simply announcing test times to emphasizing preparedness, warning performance and technological improvements, a narrative amplified by local news outlets and meteorologists who have pushed the conversation toward how better detection and clearer alerts can reduce harm.
