An estimated 1,254 people are still unaccounted for in Colorado’s devastating floods, with at least four more inches of rain in the already-soaked Boulder expected Sunday. Five deaths have been blamed on the flooding, with a fifth person presumed dead. Among the dead were a man and woman, both 19, who were swept away while leaving their car. In fact, a helicopter surveillance mission carrying Gov. John Hickenslooper and others was forced to divert twice to rescue people waving below for help. The damage of the floods is expected to cost an estimated $150 million in Boulder alone. Meanwhile, New Mexico was also hit by heavy rains, with at least one death blamed on flash floods. Officials estimate that 1,500 homes have been destroyed and about 17,500 damaged so far.
