"There may be large quantities of snow," lasting all week, said Lisa Frost of the Swedish Meteorological and Hydrological Institute. "It's quite early in the season [but] we're issuing the warning."
The expected snowfall was given a "Class 1" rating on the institute's three-level scale, indicating "certain risks for society" and the possibility of "disruption," The Local.se reported Monday.
Dalarna and Varmland counties have already received 10 centimeters (3.93 inches) of snow, and are forecast to receive an equal amount by Tuesday, the institute said.
