Avalanche advisory

David Tremper of the Utah Avalanche Center has issued an avalanche advisory for the La Sal and Abajo mountains.

“I am issuing an avalanche warning this morning for the La Sal and Abajo Mountains.  With the expected additional snow today and the expected increased winds tonight and on Tuesday, we will likely have a high danger of avalanches, especially in the upper elevation, wind exposed terrain.” Tremper said.

“The danger will depend on the amount of new snow, and especially, on the amount of wind. So carefully test the new snow as you travel by regularly digging down with your hand to see how well it’s bonded to the underlying snow and regularly jump on small, test slopes to see how they respond. The avalanche danger will range from MODERATE to HIGH depending on your choice of terrain,” Tremper said.
