Emergency managers in Pennington, Custer, Meade, and Fall River counties will conduct their annual all‑systems alert test Wednesday at 1:30 p.m. The drill activates every major warning system at once, including outdoor sirens and mobile phone alerts.
Officials say the yearly test ensures all systems are working properly and helps the public understand what a real emergency notification would sound like.
More information is available on the Pennington County Emergency Management website. After the drill, residents can fill out an online survey to help officials evaluate how well the alert systems performed
