Tornado response exposed pager and siren gaps, Jefferson County 911 board hears

Several attendees at the June 24 Jefferson County 911 advisory meeting described failures or gaps in alerting during a recent tornado, saying that elevated call volumes and partial paging failures complicated response.

"My pager did not go off," one committee member said, explaining they had to call campus security because their pager never activated. Other attendees reported their station tones dropped while many county departments did not receive pages. Members said call volume roughly doubled during the storm in a short window, driven by damage reports, downed lines and residents asking why sirens sounded.

Participants noted technical limits of outdoor sirens (they are designed to alert people outdoors and may not wake residents indoors at night) and described the reliance on pagers and mobile alerts for overnight warnings. Speakers discussed handover-notification gaps between county dispatch and some municipal or campus stations that left some units unaware of the warning in real time.

Staff said diagnostics are underway and that converters or radio-receiver upgrades may be needed to restore remote activation at some sites; two locations (a State Street site and one near an Arby's) were specifically cited as having transmission or activation issues. Staff estimated that some sirens could be back online by the end of the week, pending parts and testing.

Board members asked for follow-up reporting on diagnostic results and any changes to paging procedures to reduce gaps between dispatch, handover partners and municipal stations. The advisory group did not take formal action because a quorum was not present.
