Officials declared a disaster emergency in Colorado Friday as the Hewlett Fire rages, swallowing more than 7,600 acres in its path.

The wildfire in Larimer County prompted Gov. John Hickenlooper to sign an executive order freeing up $3 million in emergency funds for firefighting, a Colorado community radio reported. National Guard resources have also been activated to help the Forest Service battle the blaze.

The fire, which started around 1 p.m. May 14, is human-caused and is still under investigation. It has led to the evacuation of 15 homes and the closure of at least one highway.

Officials said that fire is now 15 percent contained. About 550 personnel are working to put out the blaze. Steep and rugged terrain is a difficulty firefighters are facing as they battle the fire.

Fire incident commander Todd Richardson told that the weather and lack of wind could be favorable for firefighters working to contain the fire.

We might have a few t-storms popping, pushing the weather around, he said. I think the weather overall is good because it will let the fire eat itself up within the parameter, and that means we have less to work with.
