Colorado remains under a heightened fire and heat threat Thursday as hot, dry, and windy conditions grip much of the state.

The fire — called the Twelve fire on the Bureau of Land Management’s fire dashboard — burned across 1,000 acres over the course of five hours Wednesday after sparking in Moffat County near Elk Springs, about 50 miles west of Craig, according to federal officials.

Multiple evacuation orders have been issued for Rio Blanco county in northwest Colorado due to fast-moving wildfires. The Lee Fire has nearly doubled in size as it approaches the town of Meeker.
