Council, staff review siren activations and public alerting after severe-weather warnings

Lee's Summit — After tornado warnings and severe-weather watches in the region, city emergency-management staff activated outdoor warning sirens and opened an emergency operations center. Council members raised concerns about gaps in citizen notifications and urged clearer, multi-channel communications.

Fire Chief Mike Snyder, who also serves as the city's emergency management director, described the city's response. He said the city monitors weather continuously and activated the emergency operations center at a low level as radar showed possible severe conditions. "We sound our sirens for 1 rotate 1 cycle, which is 10 minutes," Snyder said, adding that the sirens cover the entire city when activated. Snyder also said the city activated the sirens a second time when a separate tornado warning was issued farther to the east.

One siren near Chipman Road and Douglas continued to sound after staff attempted to shut the system off; staff worked with the service provider and Blue Valley Public Safety to address the malfunction.

Council and staff discussion focused on public alerting tools. Communications director Cheryl Nash noted the city uses LS Aware (Everbridge) and urged residents to sign up for the system. Council member Shields and others said they received different alert sets on their phones; Shields said she received a sequence of thunderstorm and flash-flood warnings and did not receive a tornado warning through LS Aware, while another council member reported receiving a tornado warning before the siren activation. Shields suggested the city prepare pre-approved, easy-to-post messages for social media that plainly instruct residents what to do (for example: "Take shelter in an interior room or basement until the warning expires at [time]").

Chief Snyder emphasized that outdoor warning sirens are intended to alert people outside and should not be relied on as the only notification for people inside homes: "They're outdoor warning devices. They are not intended to alert people inside their residences. We always encourage people to have additional resources... whether it's an app through your local TV station, LS Aware, etc., to assist you in being alerted." He said emergency staff will review options for more targeted activations in the future.

Ending note: Council asked staff to revisit the city's public-alert and communications procedures, including social-media messaging and LS Aware settings, to reduce confusion during fast-moving weather events and to ensure the public receives clear, local guidance.
