(IDAHO FALLS) – Air quality levels in eastern Idaho are on the decline. Idaho Falls and Rexburg are facing smoke levels that are unhealthy for sensitive groups like children and the elderly. In Pocatello, conditions aren’t much better. Federal officials say more than 1.5 million acres have burned in Idaho so far this year, more than any other state in the nation. Health officials recommend visiting a doctor if breathing problems persist for more than a few days. According to NASA, this year’s fire season will likely break the national record for most acres burned.
