Officials with Natrona County Emergency Management plan to test Casper-based emergency phone and siren systems Thursday.

The test was originally planned for last week but was postponed after a spring snowstorm impacted much of central Wyoming.

Natrona County emergency manager Stew Anderson says county residents can expect the test to begin at around noon.

“We’ll precede the siren test with a warning saying that it’s only a test, then we’ll do the sound and then follow it up again by saying that it was only a test,” Anderson said.

Anderson says individuals signed up with CodeRED, the city’s emergency notification system, may receive text messages and phone calls during the test.

“If they’re already signed up, then they should receive – if they opted to get the text messages – a text as well as a voice call saying that it’s only a test,” Anderson said.

Anderson says residents interested in signing up for CodeRED may do so at the Natrona County Emergency Management website.
