Particulate Health Issues Smoke particle size is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter (about 1/10th the diameter of a human hair) pose the greatest problems because they can get deep into your lungs. Exposure to such particles can affect both your lungs and your heart. Larger particles are of less concern, although they can irritate your eyes, nose, and throat.

Use common sense. If it looks smoky outside, it's probably not a good time to mow the lawn, go for a run, or for your children to play outdoors.

If you are advised to stay indoors, take steps to keep indoor air as clean as possible. Keep your windows and doors closed. Don’t vacuum or smoke inside to avoid increasing paticulates in your home.

Visibility and Particulate Matter - use this chart to determine your local Level of Health Concern. See chart at side for Health Concern details.

WILDFIRE - BE PREPARED Levels of Health Concern

"Good" Particulates pose little or no risk.

"Moderate" Unusually sensitive people should consider reducing prolonged or heavy exertion.

"Unhealthy for Sensitive Groups" People with heart or lung disease, older adults, and children should avoid prolonged or heavy exertion. The general public is not likely to be affected.

"Unhealthy" People with heart or lung disease, older adults, and children should avoid prolonged or heavy exertion. Everyone else should reduce prolonged or heavy exertion.

"Very Unhealthy" People with heart or lung disease, older adults, and children should avoid all physical activity outdoors. Everyone else should avoid prolonged or heavy exertion.

"Hazardous" Everyone should avoid all outdoor physical activity; people with heart or lung disease, older adults, and children should remain indoors and keep activity levels low.

Be FIREWISE If you live in or near the forest, you are responsible for reducing the fire hazards around your home. Take the Fire Risk Rating “test” (below) to see how your home scores. Then, take measures to protect your home from wildfire.

AIR QUALITY ADVISORY

Southwest Alaska #2020-F3

Thursday, June 11, 2020

LOCATION(S) IMPACTED: Yukon Delta National Wildlife Refuge and surrounding

communities.

VALID TIME: Thursday, June 11, 2020 4:00 PM to Saturday, June 13, 2020 4:00 PM, advisory

will be issued until end of the event.

TIME/DATE OF THE NEXT REPORT: Saturday, June 13, 2020 4:00 PM, if needed.

ADVISORY: Smoke from numerous fires in the Yukon Delta National Wildlife Refuge is

impacting the air quality in the region. Forecasted winds and weather will support fire growth

and increased smoke production for the next few days. Wetting rains have delayed moving into

the region, next rain event is forecasted for Saturday evening. The air quality will vary between

GOOD and VERY UNHEALTHY depending on wind flow and proximity to the fires. See the

table below for more guidance on the Air Quality Categories and Cautionary Statements.

Be aware that areas immediately downwind of any fire will experience HAZARDOUS levels of

smoke. Generally, worse conditions occur overnight and during the early morning hours, as the

atmosphere cools and brings smoke to the surface. During the day, surface heating will mix

smoke and carry it upwards, temporarily improving air quality.

SMOKE AND PUBLIC IMPACT: This is an area forecast, and as such is a general forecast for

portions of Southwestern Interior Alaska. Smoke intensity will vary depending on precise location

and local wind flow patterns. Smoke concentrations will be such that they could impact public

health at times. It is advised that travelers check local weather as smoke conditions may vary

considerably from one locality to the next. The most recent weather observations may be found on

National Weather Service’s homepage at https://www.wrh.noaa.gov/map/ . UAFSMOKE,

Wildfire Smoke Prediction for Alaska can be accessed at http://smoke.alaska.edu/PM25.html

In smoke impacted areas, DEC advises people with respiratory or heart disease, the elderly

and children should avoid prolonged exertion; everyone else should limit prolonged

exertion.

The following table contains the cautionary statements for the Air Quality for Particle Pollution.
