Thunder, lightning and ... a horn?

July 19, 2013

If you've been on main or south campus during the recent summer afternoon storms, you may have heard a siren-like horn.

That’s your cue to get inside; the university’s lightning detection system is giving a warning that there is a 99 percent chance of a lightning strike within two miles of the horn.

The system, called Thorguard, is installed near the intramural and recreation fields by the Recreation Center, at the Challenge Course near the Gardens at Spring Creek, the tennis facility near the Veterinary Teaching Hospital, and the Jack Christiansen Memorial Tracks near the Administrative Building.

A 15-second horn blast means that the system has identified the potential for lightning in the area. An amber light on the system also flashes when a warning is in effect. When you see the light or hear the horn, you should leave open areas and wait in a building for vehicle for the all-clear signal, which is three short blasts. Be sure you are taking shelter in building or vehicle; event tents are not safe.
