Dry, sunny weather “all combine to bring three days of dangerously hot weather,” the National Weather Service announced Tuesday morning, raising the potential fire hazard to a Red Flag Warning by about 2 p.m. for the interior mountains of Santa Barbara County, or the eastern Santa Ynez Range. It is possible that Sundowner winds will develop and that humidity levels could drop very low. The Red Flag Warning runs from 3 a.m. Wednesday through 8 p.m. Thursday.
