Winter storm warnings, weather advisories issued as snow continues this weekend

SALT LAKE CITY — More snow is headed Utah's way after the slow start to the season.

The National Weather Service's Salt Lake City and Grand Junction offices issued a mix of winter storm warnings and winter weather advisories throughout Utah ahead of yet another storm headed to the Beehive State this weekend.

It's set to arrive on the heels of two other storms that have impacted the state since Wednesday, adding over a foot of snow in some mountain areas and a few more inches to the valleys along the Wasatch Front to what has already fallen thus far.

"This isn't just a Wasatch Front storm, we're talking about a lot of locations (in) west and eastern Utah — with this second wave — that'll pick up snow," said KSL meteorologist Matt Johnson.

Storm timing and accumulations

Brian Head Resort in southern Utah is the snow accumulation leader from the storms that returned to Utah this week, receiving 18 inches of new snow between Wednesday and Saturday morning. Alta and Snowbird resorts also received more than a foot of snow in recent days.

The next low-pressure system is coming off the Pacific Coast in Canada and is forecast to arrive in Utah via Nevada, producing snow beginning Saturday night. Showers are expected to continue into Sunday morning with some hit-and-miss snow showers Sunday afternoon.

"Then we start to see things die down into Sunday night," he said.

A winter storm warning was issued for parts of central and southeast Utah, which will be in effect from Saturday night to 5 a.m. Monday. It states that 8 to 16 inches of snow or more will fall in the central mountains, while 6 to 18 inches of snow is forecast for the La Sal and Abajo Mountains during that time.

Lower elevations parts of both regions are forecast to receive 4 to 10 inches of snow along with wind gusts of up to 40 to 45 mph, which may "significantly reduce visibility" at times, the warnings state.

A series of winter weather advisories were issued for many other parts of the state. It takes effect Saturday evening and lingers through most of Sunday. The alerts anticipate:

• 5 to 12 inches of snow may fall in the Wasatch and West Uinta mountains. Up to 18 inches is possible in the Cottonwood Canyons, while 6 to 12 inches of snow may fall in the southern mountains.
• 4 to 10 inches of snow Wasatch Back, as well as the Tavaputs Plateau in eastern Utah.
• 2 to 6 inches of snow may fall in communities along the Wasatch Front, northern Utah and parts of southwest Utah. Higher totals are possible in the benches of those areas.
• 1 to 3 inches of snow for places above 3,000 feet elevation in Washington County, while places below 3,000 feet elevation may receive a trace an inch. As much as 6 inches is possible in upper elevations of Zion National Park.

While not included in the alerts, Johnson said places like Vernal and Moab in eastern Utah may pick up a few more inches of snow by Sunday night, as well.

Storm impacts

"Widespread winter driving conditions" are expected this weekend across most of the state, especially along mountain routes and roads by benches, the weather service notes. Traction restrictions are likely for some routes, like the Cottonwood canyons.

"Slow down and use caution while traveling," the agency wrote.

All of the new snow may also elevate avalanche danger. Utah's mountains remain in "moderate" danger as of Saturday morning; however, Utah Avalanche Center officials said Friday that "things are beginning to change and the avalanche danger is on the rise with more snow and wind expected."

"It's now necessary to develop a mindset of beginning to step back," officials wrote in a report Friday.

The additional snow will be beneficial for Utah's snowpack, which remains 70% of normal for this point in the water year, according to the Natural Resources Conservation Service.

Johnson said another storm is expected to impact Utah around the middle of next week.
