(Le Mars) — City crews are busy working Saturday morning clearing the streets of the close to seven inches of snow that fell on Le Mars. People have been seen either scooping, or using a snowblower, in their neighborhoods to clean their driveways and sidewalks of the blanket of white fluffy stuff. Strong winds from the northwest have caused blowing and drifting snow. Visibility on the roadways have been reduced to at times, near zero due to the strong winds, which has prompted the National Weather Service to issue a Blizzard Warning for Plymouth County and most of northwest Iowa. That Blizzard Warning is in effect until 6:00 p.m. this (Saturday) evening. However, as the clouds begin to part, the temperature will drop to sub-zero temperatures, and along with the winds, we will have dangerous wind chills. The weather service says the wind chill for Le Mars could drop to -25 degrees. Several parts of the state has issued a tow ban, which means conditions are determined to be too dangerous for tow trucks to be out on highways pulling stranded motorists.
