A large forest fire is burning on Lookout Mountain in Walker County.  Flames and the smoke from the fire could be seen from Teloga to the Centerpost Community as Walker County firefighters and the Georgia Forestry Commission battled the blaze on Monday.  Firefighters will be on the scene again today and will bring in reinforcements with aviation equipment from the Forestry Service.  The National Weather Service is reminding Northwest Georgia residents that dangerous fire conditions exist with low relative humidity and windy conditions and say you should NOT be burning outdoors at this time.
