On Tuesday at 5:32 p.m. the National Weather Service reported an avalanche warning in effect until Thursday at 5:45 p.m. for Colorado.

The NWS states to expect, “Heavy snow and strong winds will result in HIGH (4 of 5) avalanche danger.”

“Large and dangerous avalanches will be easy to trigger. Large avalanches will run naturally,” adds the NWS.

The full list of affected locations includes:

• Elkhead and Park Mountains

• Grand and Battlement Mesas

• Gore and Elk Mountains/Central Mountain Valleys

• West Elk and Sawatch Mountains

• Flat Tops

• Northwestern San Juan Mountains

• Southwest San Juan Mountains

• West Jackson and West Grand counties above 9,000 feet

• Eastern Sawatch Mountains above 11,000 ft

• Eastern San Juan Mountains above 10,000 ft

How to stay safe according to the NWS

Know the three factors required for an avalanche:

• Slope: Avalanche generally occur on slopes steeper than 30 degrees

• Snowpack: Recent avalanches, shooting cracks, and “whumpfing” are signs of unstable snow

• Trigger: Sometimes it doesn’t take much to tip the balance; people, new snow, and wind are common triggers

Determine if you are on or below slopes that can avalanche:

• Find out if the snow is stable

• Get the advisory: Refer to your local avalanche center for current snowpack conditions

• Get the gear and learn how to use it

Have these three avalanche safety essentials in your pack:

• Transceiver: So you can be found if covered by the snow

• Shovel: So you can dig out your partner

• Probe: So you can locate someone who has been covered by the snow

Avalanche survival rates plummet after about 15 minutes for victims who do not die from trauma. Saving your partner is up to you! Practicing realistic scenarios beforehand is essential.
