CHEYENNE, Wyo. (AP) — Major highways reopened in Wyoming and Colorado on Sunday, allowing most people to resume their holiday weekend shopping a day after snow and high winds caused blizzard conditions and clogged highways and streets with snow drifts.

After the strong winds abated early Sunday, road crews in Wyoming were able to reopen all of Interstate 25 and most of I-80 on Sunday morning. On Saturday, nearly the entire length of both interstates had closed because of the storm that also caused hazardous travel conditions in Montana.

Major interstates in Colorado that closed Saturday also were reopened by Sunday morning.

Still, travelers were warned to remain cautious for slick conditions and blowing snow.

The National Weather Service said some parts of Wyoming could see more high winds late Sunday and into Tuesday.
