Weeks of poor air quality for areas of southern Oregon and northern California will change abruptly when significant rainfall arrives Saturday into Sunday. Moderate to heavy rain is expected most areas. Drive extra carefully in areas that haven’t received rain for weeks because of oil built up on roadways. Expect greatly improved air quality over the weekend!
A brief, yet strong, atmospheric river will bring widespread wetting rain to many locations across southern Oregon and northern California. Look most of the rain to arrive around Saturday. With long periods of dry conditions over many locations, roads may be slick from oil buildup throughout the summer. There is also a low chance of flash flooding near the McCash and Lava burn scars.
Tips to stay safe during the first rain in a while. When driving, slow down and use cation. Give yourself plenty of time to reach your destination. Leave more space between you and the vehicle ahead of you. If you are traveling or recreating near recent burn scars, be on the lookout for debris flows and rock falls. Turn around, don’t drown.
