UPDATE: Fire investigators believe the cause of an early morning house fire in the Oak Hills community was likely accidental. CFD says the exact cause still undetermined as it is still under investigation.

An early morning house fire in the Oak Hills community displaces a family of three. The fire happened on the 500 block of West 45th Street just after 4 a.m.

Bruce Garner, a spokesperson for the Chattanooga Fire Department says a mother and her two adult sons live in the home. The mom was at work when the fire broke out. Her sons were alerted by loud popping noises and smoke. One of them woke their brother and fled the home unharmed.

Garner said they did not grab their cell phones before leaving the structure and were unable to call 911. The two went to a neighbors house to call for help.

When Chattanooga firefighters received the call and arrived on the scene, most of the house was on fire and flames were shooting out the eves in the attic.

Battalion Chief Lesley Morgan said it took firefighters from five fire companies about 20 minutes to get the blaze under control.

Volunteers with the American Red Cross of Southeast Tennessee responded to the scene to provide assistance to the fire victims. They tell Channel 3 that they are providing shelter for the family and resources for them until they can find a place to stay.

Chief Morgan said the house was considered a total loss, with damages estimated at $68.000.

The cause of the fire is under investigation.
