BOONE, Iowa—It doesn’t happen very often but this year, the weather during September will lead to the cancellation of the monthly test of the warning sirens in Boone County. Tests are held monthly on the first Monday of the month, at 1:00 p.m. This year, the test was delayed to Tuesday because of the Labor Day Holiday. Then the Tuesday test was delayed because of weather. Emergency Management Coordinator Lance Kooiker noted that the forecast calls for a pretty active weather pattern for the next several days, so to avoid confusion, the test of the warning siren will be cancelled. He says the next regular test will be held on Monday, October 7th at 1:00 p.m.
