Three to six inches of snow is expected to pile up in Casper from Monday night through Tuesday afternoon.

The Casper Mountain foothills will likely see more snow, with the mountain itself getting six to nine inches.

That's according to a Winter Weather Advisory issued by the National Weather Service in Riverton, in effect from 5 p.m. Monday through 5 p.m. Tuesday.

According to the advisory, snow will begin late Monday afternoon and increase in coverage after sunset.

Snow is expected to fall in periods through Tuesday, with bursts of moderate to heavy snow through Tuesday morning.

The snow is expected to taper off Tuesday afternoon.

Roads and highways will be slick and snow-packed, making travel at difficult at times.

Snowfall and blowing snow could severely limit visibilities, which could fall to a quarter of a mile or half a mile in moderate to heavy snowfall.

The advisory urges travelers to use caution, especially in open areas.
