Avalanche warning for Cascade, Western Washington Olympics

SEATTLE – An avalanche warning was issued for the entire Cascades and higher elevations of the Olympics on Thursday as an atmospheric river brings heavy snow and strong winds to the region.

According to the Northwest Avalanche Center, conditions in the mountains worsened after more than a foot of snow fell Wednesday evening.

The NWAC said avalanches large enough to kill were “very likely” at all elevations on the western slopes of the Cascades. Meteorologists warned of the likelihood of natural and man-made events. Everyone should avoid moving in avalanche prone areas, even on flat or flat terrain under steep slopes.

On the eastern slopes of the mountains and at the Olympics, the risk is high at elevations above 5,000 feet.

Avalanche danger will increase throughout Thursday as more snow falls, temperatures rise and winds peak around midday, NWAC said. At lower elevations, wet avalanche activity is possible as snow transitions to rain.

A winter storm warning is in effect for the Cascades until 10 p.m. Thursday night, and another 6 inches of snow could fall later today. In addition, strong winds could lead to snowdrift accumulations and fluctuating frost levels could further destabilize conditions.

The Olympics winter storm warning expires at 4 p.m

Even if you’re excited to try out new gear or toys, NWAC’s advice for Thursday is simple: Stay away from any area where avalanches may start, pass or stop.
