KUSA-TV in Denver reports that officials with the ski resort say they began making snow on Mambo and Home Run early Monday morning.
Temperatures dropped down into the low 20s.
Snow and cold temperatures remain in the forecast for the rest of the week and the ski area says snowmaking could continue around the clock into the weekend.
It typically takes about two weeks for Loveland’s snowmakers to cover the opening day run from tree-to-tree with an 18-inch base.
