With blistering heat and drought conditions across Oklahoma, Gov. Mary Fallin has issued a statewide burn ban. Fallin announced the ban Friday. It prohibits outdoor burning in all 77 Oklahoma counties, effective immediately. The Oklahoma Forestry Service recommended the ban after analyzing fire activities and predictions for the current drought conditions to continue. The governor's statewide burn ban supersedes all county burn bans and will remain in effect until it is lifted by the governor. The ban prohibits campfires, bonfires, fireworks and any outdoor burning. Charcoal and gas grilling is allowed if it's done at least five feet from flammable vegetation.
