Heavy snowfall came to Southcentral Alaska on Tuesday, triggering a backcountry avalanche warning for the Kenai Peninsula.

A winter weather advisory was issued by the National Weather Service Monday evening and was expected to last until Tuesday night, however, the advisory was extended until 9 a.m. Wednesday.

The advisory says total snow accumulation could reach between 4 and 8 inches, and residents should expect slippery road conditions.

A backcountry avalanche warning was issued for the mountains on the Kenai Peninsula.

The Chugach National Forest Avalanche Information Center issued the warning Tuesday morning, which will be in effect for 24 hours.

Avalanche danger is high and is expected to remain high through Wednesday, the warning said. Areas impacted include Turnagain Pass, the Kenai and Western Chugach Mountains around Eastern Turnagain Arm, Summit Lake, Lost Lake and Seward.

Strong winds combined with heavy snowfall have created widespread areas of unstable snow, the warning said. Both naturally and human-triggered avalanches are likely on slopes steeper than 30 degrees.

Backcountry travelers should stay off slopes.
