The National Weather Service posted a wind chill warning through Tuesday. Forecasters say wind chill temperatures are expected to drop as low as 65 below zero.

CenterPoint Energy has tripled service staff since Sunday and the Star Tribune reports utility crews are expected to respond to about 1,400 calls for service on Monday.

Xcel Energy also increased staff to deal with the possibility of increased calls.
