After a warm week, a nasty winter storm is set to blow in late Saturday to remind everyone that it is still winter in South Dakota.
The National Weather Service is warning people to stay off the roads, with travel becoming dangerous to practically impossible in the the central and eastern parts of the state.
Visibility will be greatly reduced by blowing snow from sustained winds of 20 mph to 40 mph, with wind gusts possibly reaching 50 mph late today and Sunday.
Central and eastern South Dakota and an area from Pine Ridge and Wall eastward are under a blizzard watch. As of Friday afternoon, Rapid City and the Black Hills were under a winter storm watch.
Alex Calderon, a meteorologist with the National Weather Service in Rapid City, said snow accumulation is expected throughout western South Dakota over the weekend.
The highest snowfall amounts will vary from a possible 6 inches to more than a foot in the higher elevations of the Black Hills.
