Gaylynn Huber, director of Sioux Falls Streets, says his crews have been on the job since last night.

"We had crews in since Sunday night.  They came in around 8 p.m. and we took care of all the emergency and secondary roads.  We also did some work around the schools this morning.  There might be some streets in residential areas where it might be a little bit slippery.  We'll go in this morning and treat them as well."

Huber urges residents to drive with caution Monday morning.
