A huge overnight downpour that brought 4 to 7 inches of rain to the area around Boulder, Colo., has already produced “massive flooding” in the streets there, The Denver Post writes.
— There’s already been one death — in a building collapse that’s being blamed on the flooding.
— At least one rural dam has given way.
— More rain is on the way Thursday.
According to the National Weather Service, a “flash flood warning remains in effect until 7:15 a.m. MDT for central Boulder County.”
The Boulder Daily Camera says that “meteorologists are calling the downpour that intensified Wednesday night — forcing evacuations in the foothills and canyons, collapsing structures, flooding city streets and killing at least one — somewhere between a 10-year and 25-year flood.”
The flooding has forced the University of Colorado Boulder to close and evacuate some residents to higher-lying parts of the campus.
Census Bureau data show there are about 305,000 people in Boulder County — 102,000 in Boulder city alone.
