Medford, Ore. – Fire danger is escalating across southern Oregon and far northern California as back-to-back Red Flag Warnings remain in effect through Wednesday evening. Forecasters warn that abundant lightning on critically dry fuels could trigger multiple new wildfires, with storms capable of producing outflow winds up to 50 mph.
According to the National Weather Service in Medford, the warning covers Siskiyou, Modoc, and Shasta counties in California, along with the Umpqua National Forest, Klamath Basin, and south-central Oregon deserts. A second warning was issued by the Portland office for the Northern and Southern Willamette National Forests, effective from 9 a.m. to 9 p.m. Wednesday.
Scattered thunderstorms are expected to develop Wednesday afternoon. While some rainfall is likely, strikes outside storm cores pose the highest ignition threat. Officials caution that gusty outflow winds could spread flames unpredictably, even miles from where lightning first touches down.
Communities near Medford, Klamath Falls, and Mount Shasta should be prepared for possible rapid fire growth. Emergency managers urge residents to review evacuation plans, charge phones, and follow all fire restrictions. Outdoor burning and use of spark-producing equipment remain discouraged.
Both warnings remain in effect until 9 p.m. Wednesday, with conditions expected to ease overnight. Additional advisories may follow if storm activity lingers into late week.
