POCATELLO (AP) - The National Weather Service is warning motorists to be cautious this weekend as a winter storm is expected to bring several inches of snow across parts of Idaho.

The weather service in Pocatello on Saturday issued a winter storm warning for moderate snow in eastern Idaho.

The service also says gusts may create hazardous conditions at times as winds blow snow already on the ground from a previous Christmas storm.

A winter weather advisory on Saturday said heavy snow is also in the forecast for the mountains of the Idaho panhandle.
