Description:
* WHAT...The Minnesota Pollution Control Agency has issued an Air
Quality Alert for fine particles pollution. The Air Quality Index
(AQI) is expected to reach the Purple or Very Unhealthy category.
* WHERE...Northeast Minnesota.
* WHEN...From 7 AM CDT Tuesday to 11 AM CDT Thursday.
* IMPACTS...The risk of health effects is increased for everyone.
* ADDITIONAL DETAILS...Heavy smoke from several large wildfires
across northeast Minnesota and Canada will move south behind a
frontal boundary across much of northeast Minnesota beginning on
Tuesday. High temperatures will be in the 90s across the alert
area Tuesday, and the combination of wildfire smoke and extreme
heat amplifies health risks. Heavy smoke may move further south
into Minnesota Tuesday night into Wednesday morning, so the air
quality alert may need to be expanded. Additional rounds of heavy
smoke are possible across the region through at least Thursday
morning.
Instruction:
Sensitive groups, such as people with lung disease (including
asthma), heart disease, and children and older adults, should
avoid all physical activities outdoors. The general public should
avoid prolonged or heavy exertion. Reduce or eliminate activities
that contribute to air pollution, such as outdoor burning, and
use of residential wood burning devices. Reduce vehicle trips and
vehicle idling as much as possible. Keep windows closed overnight
to prevent smoke from getting indoors.
