Air Quality Alert issued July 19 at 12:52PM PDT by NWS Medford OR

8 months 2 weeks ago
Oregon Department of Environmental Quality has issued an Air Pollution Advisory...in effect until 5 PM PDT Monday. The Oregon Department of Environmental Quality issued an air quality advisory for Klamath and northern Lake counties due to numerous wildfires burning in the region. DEQ also expects other areas of the state may see intermittent smoke from ongoing large wildfires, including eastern Douglas and northeast Jackson counties. 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. 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. DEQs color-coded Air Quality Index provides current air quality conditions and ranks air quality as follows: Green is good. Yellow is moderate. Orange is unhealthy for sensitive groups such as children, the elderly, pregnant women and those with respiratory conditions. Red is unhealthy for everyone. Purple is very unhealthy for all groups. Maroon is hazardous. For additional information...please visit the web site at https://oregonsmoke.org

Fire Weather Watch issued July 19 at 12:07PM PDT until July 21 at 8:00AM PDT by NWS Medford OR

8 months 2 weeks ago
An upper level low will move up from the south along the California coast Saturday, and will tap into some moisture that is expected to increase late Saturday afternoon into Saturday night. At the same time elevated instability will increase along with a moderate to strong trigger which could result in isolated to possibly scattered thunderstorms in the overnight period Saturday into Sunday morning. Given how dry fuels are along with the recent hot stretch, lightning efficiency will he high despite storms coming in during the night. The National Weather Service in Medford has issued a Fire Weather Watch, which is in effect from Saturday afternoon through Sunday morning. * IMPACTS...Given the recent prolonged stretch of very hot and very dry conditions, lightning efficiency will be high to very high for fire starts. Any fires that develop will likely spread rapidly. Additionally, winds will allow for new and existing fires to grow rapidly out of control. * AFFECTED AREA...All of Fire Zones 615, 616, 617, 618, 619, 620, 622, and 623. * THUNDERSTORMS...Isolated to scattered thunderstorms are possible Saturday night. Lightning strikes outside of precipitation cores are possible and cause for concern. * OUTFLOW WINDS...Gusts up to 40 mph. These outflow winds can travel up to 50 miles away from the thunderstorm that caused it. * DETAILED URL...View the hazard area in detail at https://www.wrh.noaa.gov/map/?wfo=mfr
