Lyons - Flash flooding in Colorado has left two people dead and the widespread high waters are keeping search and rescue teams from reaching stranded residents and motorists in Boulder and nearby mountain communities as heavy rains hammered northern Colorado on Thursday.

The National Weather Service warned of an "extremely dangerous and life-threatening situation" throughout the region as the flooding forced people from their homes, canceled classes and led to mudslides and rockslides in some areas.

"Move to higher ground now. Act quickly to protect your life," the Weather Service warned in numerous bulletins that went out throughout the morning.


Boulder Office of Emergency Management spokeswoman Gabrielle Boerkircher said volunteers were trying to help stranded people until emergency crews could arrive because many roads were impassable.

The National Weather Service warned of an "extremely dangerous and life-threatening situation" throughout the region.

Boerkircher told The Associated Press one person was killed when a structure collapsed in the tiny town of Jamestown. She had no additional details.
