DENVER (September 15, 2013)--Helicopter crews were planning to expand their searches Sunday for people stranded by flooding in Colorado, but the plans could be hampered by more rain.
The National Weather Service says as much as 2 more inches of rain could fall Sunday, which could mean more flooding and mudslides.
Rescuers have been making progress reaching communities cut off by flooding, but many canyon roads are still either underwater or washed out, and authorities say they don't have an estimate of how many people are still stranded.
In the hard-hit town of Lyons north of Boulder, rescuers were holding their breath because the only bridge into the town was beginning to crumble.
The National Guard planned to resume airlifts Sunday with help from additional crews from Wyoming.
Guard officials say as of Saturday night, 1,750 people and 300 pets have been rescued either by air or on the ground.
So far the effort has been focused on Boulder and Larimer Counties, but if the weather permits, crews plan to expand the search area Sunday to Longmont, Fort Collins, Fort Morgan and Weld County.
