When there is a storm coming, or immediately after a storm, anyone headed into the backcountry should call the Utah Avalanche Center, which is the best source for avalanche conditions. The number is 888-999-4019.

There are five warning levels — low, moderate, considerable, high and extreme. Backcountry travelers should use caution when the warning is considerable or higher.

There are seven avalanche areas in Utah, each with a staff of avalanche forecasters who are out in the field daily reporting on current conditions. Those centers are Logan, western Uinta, Ogden, Salt Lake City, Provo, Manti-Skyline and Moab.

Along with a detailed advisory, the centers also offer educational information and weather forecasts.

The Web site is www.utahavalanchecenter.com.

The DPR also has 17 trail maps identifying groomed trails in Utah. The maps are free. For information call 800-648-7433.
