More than 70 Colorado firefighters from 13 fire departments continue to fight a 30,000-plus acre grass fire in northeastern Logan County. Officials have confirmed that there were four structures lost, including three homes.

A 9-1-1 call was received at 11:30 a.m. reporting a fire east of Sterling in the Proctor area. The fire was heading east-northeast, and jumped Interstate-76 before spreading into Phillips County. A portion of I-76 was closed due to poor visibility from smoke as well as blowing dirt, but has reopened. Local road closures are in place.

A pre-evacuation notification was made to more than 900 phone numbers and a Red Cross shelter set up in Sterling.

Wind, gusting to nearly 50 miles-per-hour, is driving the fire, but is expected to decrease overnight.

There are no reported injuries, and no estimated time for containment.
