A strong winter storm set to hit much of Wyoming through Thursday morning is expected to bring significant snowfall, particularly for the southeastern part of the state.

While Casper could see five to 10 inches of new snow, according to a revised winter storm watch from the National Weather Service, the situation could be much more serious on Casper Mountain. There, the NWS predicts some 20-30 inches of new snowfall.

In Natrona County, winds could gust up to 40 mph.

The watch is in effect from Wednesday morning through late Wednesday night.

Travel could be very difficult. Interstate 25 is among the arterial highways which are expected to see areas of significantly reduced visibility resulting from blowing snow.

A winter storm warning has been issued for all of Albany, Carbon, Converse, Niobrara, Platte, and Weston Counties. It also includes part of Crook County as well as small parts of western-most Laramie County.

But the primary concern for Laramie County, along with Goshen County, is a blizzard warning. Some 10-18 inches of snow is expected to fall, and wind gusts up to 65 mph will cause significant drifting snow.

"Travel could be very difficult to impossible with snow-packed roads," the blizzard warning reads in part. "Blowing snow could significantly reduce visibility causing whiteout conditions."

In its blizzard warning, the NWS goes on to say, "Do not travel. If you must travel, have a winter survival kit with you. If you get stranded, stay with your vehicle and wait for help to arrive."
