The National Weather Service has issued a Red Flag Warning from 1 p.m. to 10 p.m. Thursday, June 18, for portions of Lassen, Alpine and Mono counties. Additionally, a fire weather watch has been issued for portions or Humbolt, Trinity, Siskiyou, Modoc, and Lassen counties. A mix of wet and dry thunderstorms could produce isolated dry lightning and erratic outflow winds gusting around 50 mph.
