Residents along Colorado’s northern Front Range were still battling at mid-day Friday the effects of what state officials are calling “historically significant” rainfall and “biblical floods” along the foothills and across the Denver metro area.
Some communities, including Boulder and those along the I-25 corridor north to Fort Collins, have received 12-15 in. of rain since the storm intensified on Tuesday night—nearly half of the average annual precipitation for the region. That is the equivalent of snowmelt from 9.5 ft of snow.
