City of Muskogee: sirens failed prompt activation due to communication disruption

In the aftermath of Tuesday's tornado in Muskogee and the failure of the tornado sirens to go off until after the EF1 twister (with a final path length of 14.3 miles) had blown through southern neighborhoods in the city, officials have tracked down the issue that caused the delay:

Statement on Outdoor Warning Siren Activation

MUSKOGEE, Okla. April 17, 2026 -  The City of Muskogee is providing an update regarding the delayed activation of the Outdoor Warning System during the severe weather event on April 14, 2026.

Following an extensive investigation by the contractor responsible for maintaining and servicing the Outdoor Warning System, the City of Muskogee has been informed of the conditions that prevented the timely activation of the sirens.

The investigation found that the system controlling the sirens functioned properly and issued the activation command immediately after the tornado warning was released by the National Weather Service. However, a disruption in the system’s communication link prevented that activation command from reaching the sirens.

When the primary system was unable to complete the activation, it automatically initiated a failover to the backup system located at a secondary site within Muskogee. The backup system also generated and sent the activation command as designed. However, the storm had generated a power surge that unknowingly tripped the surge protection breaker on the backup radio, which is a critical component used to transmit the signal to the sirens. Because the radio was not operational, the backup activation signal was not transmitted to the sirens.

System logs reviewed by the contractor confirm that the automatic activation commands were sent at the same time the tornado warning was issued. In addition, multiple remote activation attempts were made by Emergency Management personnel during the event when it became clear the sirens were not sounding. Those attempts were also unsuccessful due to the same communication failures.

The City of Muskogee and its contractor have since resolved the communication issues to ensure a reliable connection between the control system and the Outdoor Warning Sirens.

The City remains committed to maintaining a dependable emergency warning system and will continue to monitor and improve system performance moving forward.
