The issue that resulted in a false tornado warning on the county’s emergency alert system, NotifyJoCo, has been identified and resolved.
Johnson County Emergency Management officials worked in coordination with the system’s vendor to identify a setting issue that inadvertently triggered the notification. The setting in the system resulted in the system identifying one contact’s request for notification of weather warnings in Johnson County, Texas, and when a tornado warning was issued for that area, it inadvertently sent notifications to contacts requesting warnings for Johnson County, Kansas.
“In working with the vendor, we were able to identify the issue and resolve it,” said Dan Robeson, Johnson County Emergency Management Coordinator. “We apologize for any inconvenience this caused.”
The false alert happened at 5:16 p.m. and went to approximately 18,000 contacts. Staff in the Emergency Operations Center were able to stop the message and send a notice to the contacts in the system alerting them it was a false alarm by 5:29 p.m.
