* AFFECTED AREA...Fire Weather Zone 652 West Portion of the Olympic Mountains and Fire Weather Zone 661 East Portion of the Olympic Mountains. * THUNDERSTORMS....Scattered chance of thunderstorms over the Olympic mountains with LAL 3 during the morning and afternoon hours. * OUTFLOW WINDS...Gusty and erratic winds are possible in the vicinity of any thunderstorms that develop. * IMPACTS...Scattered lightning in dry fuels can cause multiple fire starts. Thunderstorms can also bring sudden sharp wind shifts on existing fires, causing rapid changes in a fire's rate of spread and direction of spread. Thunderstorm outflow winds can be a threat for several hours following the start of a new lightning-caused fire. If a fire were to begin, air quality may diminish in the surrounding area.

Jackson County Public Health has issued an air quality advisory for Jackson County through Monday due to numerous wildfires burning in the region. The wildfire smoke combined with forecast conditions will cause air quality levels to fluctuate and could be at unhealthy levels. Depending on weather patterns and fire activity, air quality could be impacted for longer. 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.
