SNOQUALMIE PASS, Wash. - Authorities say two people are missing after a pair of avalanches in the mountains in Washington state.

Initial reports said as many as three people were missing, but officials now say two are unaccounted for after the avalanches hit two separate groups.

At one spot, three people were snowshoeing. KING-TV is reporting that one is missing, another has shoulder and hamstring injuries and the other was not hurt.

At the other site, 13 people were in the area near where the avalanche struck. One person is missing and another is reportedly suffering from hypothermia and unable to walk. The group has been told to stay put as rescue workers try to reach them.

The avalanches occurred as heavy snow was falling in the Cascade Mountains east of Seattle.
