KOOSKIA - Based on monitoring by avalanche specialists and a forecast of colder temperatures, US-12 is anticipated to reopen Tuesday afternoon between Fish Creek (milepost 126) and Saddle Camp Road (milepost 139). Although no avalanches occurred, considerable hazard prompted the closing of the highway Sunday afternoon for the safety of drivers and recreationists.
The highway could reopen as early as 12:00pm PT, but drivers should check 511.idaho.gov for updated information before traveling as conditions could change.
Avalanche specialists rely on the forecast and data provided by weather stations—one at Bald Mountain and one at Powell—to determine the risk for drivers. The station at Powell was installed last fall, and another station will be placed at Castle Butte later this year to better forecast avalanche hazard along US-12.
The last avalanche to reach US-12 was in 2008.
