Local authorities have asked more than 32,000 people to evacuate as what is already known as the Marshall fire has massacred land and houses since Thursday morning (11am local time).
Boulder County Sheriff Joe Pelle said at a news conference that an estimated 580 homes have currently been lost to the flames or damaged.
He added that one officer was injured.
Breaking down the numbers, Sheriff Pelle said 370 homes were lost in east Superior, and an additional 210 may have been destroyed in the Olde Town area.
Sheriff Pelle said no fatalities have yet been reported, but given the speed and scope of the fire, “it wouldn’t surprise us if we did find a casualty.”
He added: “My county is on fire.”
The intense Colorado winds boosted the fire to the extent that by 3pm, the smoke turned daylight into dusk.
A spokesperson for UC Health in Broomfield confirmed six burn victim patients.
Governor Jared Polis told reporters: “This is awful.”
“There is no way to quantify the price of a loss.”
