Sioux City Fire Rescue and Woodbury County Emergency Services have four scenarios where our outdoor warning sirens will be activated.
Assistant City Fire Chief Jim Clark says the first two are when the National Weather Service has issued a tornado warning for the area or when a tornado has been spotted by a trained weather spotter.
Clark says the most recent siren activation involved a third reason, involving a severe thunderstorm warning with damaging winds of 70 mph or greater:
OC…..HAD SOME DEATHS. ;20
That policy was adopted locally over three years ago.
Clark says a high wind warning will be issued for the entire county instead of one or two towns:
OC…..OTHER SIRENS. :22
Clark says the 4th scenario is when Law Enforcement or Fire personnel instruct the Communications Center to sound the sirens for a potential bio-hazard where people would be safer indoors:
OC…FOR THOSE. ;16
Clark says when residents hear the sirens, they should immediately go inside a sturdy structure to the lowest level without windows and then turn on a communication device such as a weather radio, their computer or a media outlet like KSCJ to listen for information relating to the warning.
