The Cheyenne/Laramie County Emergency Management Agency will be testing the outdoor warning siren system at 10 a.m. Friday in Pine Bluffs and at noon Friday in Cheyenne and surrounding towns. The warning system will sound a steady signal for a period of one to three minutes.

During an actual emergency, when residents hear the sirens they should take cover immediately and tune into a local radio or television station to receive additional emergency information. Residents should not call 911 or local emergency officials for imformation as this ties up telephone lines needed for emergency operations. The sirens are an all-hazards emergency warning system and are intended to warn residents of any life threatening situation in the area.

Cancellation of the test may occur due to inclement weather.
