IDAHO FALLS — There are a large number of severe weather alerts in eastern Idaho for Sunday, March 5.

A winter storm warning is in effect for the following counties: Clark, Fremont, Teton, Bannock, Caribou, Bear Lake, western Madison, western Bonneville and western Bingham. Wet, heavy snow is expected in the region through Monday evening with 5 to 8 inches predicted in areas above 6,500 feet and 2 to 4 inches in the valleys.

Winds of 15 to 20 mph will cause blowing and drifting snow on the roadways.

Northern Utah and western Wyoming are under the same advisory. Central Idaho is under a winter storm warning with up to 15 inches possible in the mountains, according to the National Weather Service.

The flood watch remains in effect for the following counties: Bonneville, Madison, Bingham, Bannock, Jefferson, Butte, Caribou, Franklin, Oneida and Power. Rainfall and rising temperatures in the lower elevations will result in snow melt.

The rapid snow melt may cause pooling of water and flooded roadways at low water crossings. Some roads may become washed out, and homeowners situated in areas of poor drainage may experience flooding.

Road closures are possible due to the storm Sunday.

Thus far the Idaho Transportation Department has issued a difficult driving warning for Idaho Highway 31 between Swan Valley and the Wyoming State Line and Idaho Highway 33 between Driggs and the Wyoming State Line. The roadways are wet and covered in slush.
