Residents near the 2024 burn areas associated with active wildfires should prepare for potential flooding impacts. Be sure to stay up to date with information from local authorities. Heavy rainfall could trigger flash flooding of low-lying areas, urbanized street flooding, and debris flows in and near recent wildfire burn scars. * ADDITIONAL DETAILS... - National Weather Service Meteorologists are forecasting heavy rainfall, which may lead to flash flooding and debris flows over recent burn areas in the Cascades.

...STRONG TO SEVERE THUNDERSTORMS WILL IMPACT THE CASCADE MOUNTAINS TODAY, EXTENDING TO THE EASTERN SLOPES, WHILE SOUTHEASTERN OREGON SEES DRY, WINDY, AND UNSTABLE CONDITIONS... .A potent weather system will bring a myriad of impacts to the forecast area today. For the Cascade Mountains and east slopes, strong to severe thunderstorms will trek across primarily the spine of the Cascades starting in the afternoon down around central Oregon, advancing northward into the Washington Cascades by the evening. While storms along the Cascades are expected to be accompanied by a significant wetting rain, isolated to scattered storms extending into the east slopes and portions of the Columbia Basin will be much drier, leading to critical fire weather conditions due to abundant lightning with a lack of wetting rain. For southeastern Oregon, this same weather system will usher in hot and dry desert air, leading to breezy winds combined with low RHs and locally unstable conditions. Showers and storms are not anticipated to track as far east as southeastern Oregon. Users should note that OR641 and WA691 are under partial Red Flag Warnings. The Warned zones include only the western half of each zone, and not the entirety of the zone. * AFFECTED AREA...Fire Weather Zone 642 Southern Blue and Strawberry Mountains. * WINDS...South 10 to 20 mph with gusts up to 30 mph. * RELATIVE HUMIDITY...As low as 10 percent. * IMPACTS...Gusty winds with dry conditions may lead to rapid fire spread.

Oregon Department of Environmental Quality has issued an Air Quality Advisory...in effect until noon PDT Monday. This air quality advisory covers Lake and northern Klamath counties due to wildfires burning in the region. The DEQ also expects intermittent smoke in eastern Douglas and Jackson County through this period due to smoke from surrounding fires. The wildfire smoke combined with forecast conditions will cause air quality levels to fluctuate and could be at unhealthy levels. Smoke levels can change rapidly depending on the weather and planned burn operations. Smoke can irritate the eyes and lungs and worsen some medical conditions. People most at risk include infants and young children, people with heart or lung disease, older adults and pregnant people. People can take the following precautions to protect their health: - Follow local burn restrictions to prevent deteriorating air quality. - Avoid strenuous outdoor activity during periods of poor air quality. - People with heart or lung problems and young children are especially vulnerable. These people should stay indoors while smoke levels are high. - Use certified High Efficiency Particulate Air (HEPA) filters in indoor heating, ventilation, cooling and air purification systems. - Avoid using wood-burning stoves and other sources of indoor smoke if possible.
