 For NPR News in the Twin Cities, I'm Kerry Finnelli. Xcel Energy officials say about 1,200 employees are working to fully restore power before tomorrow. Severe storms swept through late Saturday and early Sunday, causing power outages for tens of thousands of Minnesotans. About 20,000 customers remain without power as of this afternoon, mostly in the West Metro. Xcel Energy officials are advising people to call them directly with any questions or concerns.
