Boone County emergency officials are working to end some confusion.
More than a dozen people called 911 after they thought a second outdoor warning siren gave an â??all clearâ?? signal during last night's tornado warning.
As Thursdayâ??s severe weather passed through Mid-Missouri, people in Boone County heard 2 warning sirens within minutes of each other. Some people, like Kelly Draehn, thought the second warning siren meant â??all clearâ??.
Draehn said, â??I checked the weather after the first one. They said the warning was until 5:30. The second one came around 5:30 and the weather didnâ??t seem that bad.â??
Warning sirens never sound an â??all clearâ??. They warn people to take cover and get the latest weather information from your TV or radio. Emergency officials have a plan to divide Boone County into northern, central and southern zones. Right now, every siren goes off when the National Weather Service issues a warning for anywhere in Boone County.
Emergency Management Director Scott Olsen said, â??Clearly, there are times when storm cell systems come into the county that are only in one part of the county and the other part of the county, essentially, has blue skies. You donâ??t want people to have a sense of complacency about how they respond to sirens.â??
Boone County officials are in the process of adding more sirens and upgrading their existing sirens with better testing equipment. They hope the changes bring a better understanding of their warning system. Olsen hopes to have the upgrades complete and the new zoning plan in place within the next 3 months.
