• Abstract:
  Highway snow avalanche forecasting programs typically rely on weather and field observations to make road closure and hazard ; evaluations. Recently, infrasonic avalanche monitoring technology has been developed for practical use near Teton Pass, WY to ; provide another tool for Wyoming State Highway 22 technicians in their operational forecasting and decision making. The technology ; detects low frequency sound waves produced by avalanches with automated near real-time processing provided to facilitate an alarm. ; Monitoring system operation provides information to confirm results from avalanche control work, notification of natural avalanche ; events, and verification of explosive detonations. The ability to monitor avalanche activity in poor visibility and confirm avalanche control ; work results are powerful tools for assessing highway avalanche hazard and has changed the way WYDOT operates in its mission to ; provide a safe and efficient transportation route.
