(WICHITA, Kan.) — If you heard the tornado sirens go off for a short time Monday you should know there was no severe weather threat.
Instead, the sound was part of the "calibration process," according to Sedgwick County Emergency Manager Randy Duncan.
Duncan tells Eyewitness News the calibration is part of the upgrade of tornado sirens in Sedgwick County. Calibration causes crews to activate the device for 30 seconds or less.
"If you hear a device going off and the sky is sunny and it only lasts for a short period, odds are you're hearing part of the calibration procedure," says Duncan. He adds that crews will not calibrate the sirens if the skies are overcast or when there's a threat of severe weather.
Crews were in the South Seneca area Monday. The calibration procedures will continue until the job is done, which could happen within the next couple of weeks.
