Oregon Department of Environmental Quality has issued an Air
Quality Advisory...in effect until 11 AM PDT Tuesday.
The advisory is in effect for all of Klamath County, including
Crater Lake, Chemult, Crescent, Chiloquin, Klamath Falls, Sprague
River, Beatty, and Bly.
Wildfires burning in the region 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. People 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.

* AFFECTED AREA...In Oregon, Fire Weather Zone 689 Northern
Willamette National Forest and Fire Weather Zone 690 Southern
Willamette National Forest.
* THUNDERSTORMS...A 20 to 25% chance of thunderstorms. Storms may
produce very little rainfall, especially initially. This will
increase the potential for new fire starts with any cloud to
ground lightning that occurs.
* OUTFLOW WINDS...Instantaneous gusts as high as 40 mph. Gusts at
these speeds can be observed tens of miles away from the core of
the thunderstorm.
* DRY AND UNSTABLE...Unstable conditions with elevated mixing
heights may promote pyroconvective activity.
* IMPACTS...Conditions may be favorable for rapid fire spread
which may threaten life and property. Thunderstorm outflow winds
may result in unanticipated erratic fire spread. High
instability may result in fire growth. Frequent lightning and
critically dry fuels may result in new fire starts.
* WHAT...Afternoon high temperatures in the mid to upper 90s and
overnight low temperatures in the mid 60s to lower 70s expected.
* WHERE...Western and Central Columbia River Gorge and the Hood
River Valley.
* WHEN...From noon Tuesday to 9 PM PDT Wednesday.
* IMPACTS...Hot temperatures may cause heat illnesses.

temperatures a bit on Wednesday when compared to Tuesday. However,
probabilities for high temperatures above 90 degrees on Wednesday
are high, ranging from 80-90%.
* WHAT...Afternoon high temperatures in the mid to upper 90s and
overnight low temperatures in the mid 60s to lower 70s expected.

lightning possible. Storms may produce little or no rain, and
lightning strikes outside of precipitation cores are
possible, and may cause many new fire starts.

to 25 miles from thunderstorm cores.
* ADDITIONAL DETAILS...IN addition to thunderstorm potential,
conditions on Tuesday will be hot, dry, breezy, and unstable,
