ROLLA, Missouri- The Rolla Police Department says at approximately 4:22pm on June 26, 2018, Central Communications received notification that West Central Phelps County was under a Tornado Warning until 4:45pm.

Telecommunicators immediately attempted to activate the Outdoor Storm Warning Sirens and due to an undetermined system malfunction, the City of Rolla Storm Sirens did not activate.

As part of our protocol, all other emergency alert systems operated correctly including the Everbridge phone notification system, Missouri S & T Rave alert, the Fidelity Cable Emergency Alert System, and public radio outlets notification.

Immediately upon recognition of a system malfunction, staff checked physical equipment for any errors and reached out to our radio service provider to identify any workable solutions. Unfortunately, continued attempts were unsuccessful.

At this moment, a technician is responding to the City of Rolla to provide immediate technical support in repairing the Outdoor Storm Warning System. police said.

“The City of Rolla Outdoor Storm Warning Sirens are tested monthly. The last test was on June 6, 2018, and all systems functioned without issue.”
