Afternoon Drill – 1:45 p.m. The drill traditionally occurs on Thursday afternoon at 1:45 p.m., when jurisdictions across Minnesota sound their outdoor warning sirens. Schools, businesses and other facilities are encouraged to conduct a tornado drill at this time to practice their tornado sheltering plans. Most local and statewide radio, TV and cable stations will be participating in the drill. Television viewers and radio station listeners and TV viewers should hear or see a simulated tornado warning message at 1:45 p.m. This tornado drill warning should last about one minute. When the test is completed, stations should return to normal programming.
Evening Drill – 6:45 p.m. The reason for a 6:45 p.m. drill is that severe weather including tornadoes occurs most often between 3 and 8 p.m. The statewide 1:45 p.m. drill gives institutions, first-shift and day workers a time to practice, but it does not allow second-shift workers the same opportunity. The 6:45 p.m. tornado drill also allows families to practice their sheltering plans.
