Ask Cam

Sound the Alarm for Lightning!

July 19, 2011

Hey CAM, what are those horns I hear sometimes during the summer afternoons?

Question: Hey CAM, what are those horns I hear sometimes during the summer afternoons?

CAM’s response:  A fine question from someone with a keen ear (actually, there is nothing harmonious about this tune. You know it when you hear it.) What you are hearing is a lightning klaxon, an electromagnetic horn set to sound when atmospheric conditions are right for lightning strikes.

These klaxons are spread across campus and located in areas where people are likely to be out in the open, like the intramural fields, Christiansen Track and the Ropes Course. Of course, these horns are only a warning and can’t prevent a strike.

Colorado weather moves quickly, and afternoon thunderstorms pop up sometimes without warning. Don’t take a risk, take shelter.
