After the drought, parts of Colorado around the Boulder region have seen as much as 7 inches (17cm) of rain in just 3 hours on the morning of Thursday September 12th. Further heavy rainfall is still expected.
Governor John Hickenlooper described it as “a staggering amount” of rainfall. “Given the drought situation we’ve had, it was almost a year’s worth of rain.”
Three people have died in the floods in 3 separate incidents, one in Boulder, one in Jamestown and the other in Colorado Springs.
Residents in several towns, including Boulder, Jamestown, Fourmile, Loveland and Longmont have been evacuated to higher ground. Emergency help centers have been set up. Flood water and debris have blocked many roads, making rescue operations more difficult.
Emergency alerts were sent out by the Boulder Office of Emergency Management for Boulder Creek, around midnight on September 12th, due to rising water levels along Boulder Creek. Flood sirens were sounded and telephone alert messages sent out to around 8,000 residents.
According to Boulder Office of Emergency Management:
A large surge of water, mud, rocks and debris, including cars, about 30 feet deep is heading down Fourmile Creek, according to an 11:10 p.m. call to Boulder County by a resident of Emerson Gulch. The flow is expected to reach Boulder Creek at about midnight. Residents are warned to go to higher ground!
