SALT LAKE CITY — A weather alert will remain active in Salt Lake County through Sunday, and off-and-on showers will be present until Tuesday according to KSL meteorologists and the National Weather Service in Salt Lake City.

Salt Lake City awoke to a cold and wet Sunday after an overnight chill brought valley rain and mountain snow. At approximately 4:30 p.m., the Utah Highway Patrol warned Salt Lake County residents that there had been at least 94 crashes statewide with a vast majority being in the Salt Lake Valley.

"Please slow down, give yourself plenty of time and space as you travel. Eliminate distractions and wear your seat belt. We ask you to delay your travel until conditions improve," UHP said, in a post made on X.

The National Weather Service in Salt Lake City said "a band of heavy graupel and thundersnow" was moving through the valley, creating the slippery road conditions.

According to KSL meteorologist Kristen Van Dyke, Sunday morning's showers were likely a result of lake effect coming from the Great Salt Lake. Van Dyke said continued rain and snow-mixed showers would move through the valley until Tuesday. The low temperatures for Sunday evening were estimated in the mid-30s, she said.

Brighton and Snowbird resorts reported more than a foot of snow overnight, and snow showers are expected to continue off and on Sunday in the mountains.
