Authorities have closed a portion of Interstate 80 in western Nebraska because of hazardous driving conditions caused by a spring storm.

The state Department of Roads says Wednesday that the westbound lanes of the interstate are closed between Big Springs in western Nebraska and the Wyoming state line. The Wyoming Department of Transportation requested the closure due to hazardous driving conditions in Wyoming.

The National Weather Service says the storm may drop several inches of snow in western and north central Nebraska between Wednesday and Thursday morning. Several winter weather advisories are in effect through Thursday as the storm moves east.

Strong wind gusts of up to 20-30 mph will cause blowing and drifting snow.

Authorities are advising drivers to reduce speed because of the snow.
