Houses and structures were engulfed by a “fire storm” of flames on the evening of December 30 in Boulder County, Colorado, firefighters said.

Local officials ordered the evacuation of Louisville and Superior, both located southeast of the city of Boulder, amid what the National Weather Service described as “life-threatening” conditions.

Around 35,000 people were evacuated and approximately 600 houses were destroyed, according to local news reports.

The Marshall Fire was an estimated 1,600 acres in size by Thursday afternoon, with Colorado Gov Jared Polis declaring a state of emergency.
