The tests will involve all radio-controlled sirens withing a 10 mile radius of the Fort Calhoun Station.
As long as there is not severe weather in the area, the sirens will sound for a full four minutes some time between 9 and 10 a.m. Tuesday.

OPPD does the test annually to make sure everything is working correctly.
