DENVER (AP) - Helicopter crews plan to expand their searches for people who are stranded but may be hampered by more rain.
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 with Wyoming crews arriving to aid the effort. Officials say they plan to expand the search area to Longmont, Fort Collins, Fort Morgan and Weld County.
The National Weather Service says the rain is expected to pick up again throughout the day.
Larimer County sheriff's spokesman John Schulz says the rain could delay or ground the air searches.
The weather service says up to 2 inches are expected, creating the risk of flash flooding and mud slides.
