A Utah snowmobiler accidentally triggered an avalanche that buried his brother, whom he was able to save after spotting his fingers sticking out of the snow. The brothers and their father were riding snowmobiles across the slopes in the Franklin Basin area of the Utah backcountry near the Idaho border, according to the Utah Avalanche Center.

Seventeen million people across the South are under the threat of damaging winds, strong tornadoes and hail Saturday as the region braces for more potential destructive storms.

Tornadoes with three second gusts of between 111 miles per hour and 135 miles per hour could hit the southeastern U.S. over the weekend.

The Avalanche have signed recently acquired goalie Mackenzie Blackwood to a five-year contract extension, with a source saying the deal carries an average annual value of $5.25 million against the salary cap.
