DENVER — Military helicopter crews are expanding their searches for people who are stranded with more rain expected to fall in flooded areas.
National Guard officials say most of the 1,750 people and 300 pets rescued as of Saturday night have been in Boulder and Larimer counties.
The airlifts are to resume Sunday and also will include Longmont, Fort Collins, Fort Morgan and Weld County.
The National Weather Service says the rain is expected to pick up again throughout the day in the mountains and foothills.
Between a half-inch and 2 inches are expected to fall in the area, creating the risk of flash flooding and mud slides.
