Anchorage has closed two of its three emergency warming rooms as temperatures climbed out of the negatives. According to a press release from Mayor Dave Bronson’s office, the warming rooms at the The Aviator Hotel downtown and the former Golden Lion Hotel in the Midtown area were not heavily used and closed on Sunday morning. A third emergency warming room that saw higher use at the city’s Cold Weather Shelter on 56th Avenue is expected to remain open through next Tuesday.
