Details: 
...AIR QUALITY ALERT IN EFFECT FROM NOON CDT TO 9 PM CDT FRIDAY...

* WHAT...The Minnesota Pollution Control Agency has issued an Air
Quality Alert for ozone pollution. The Air Quality Index (AQI) is
expected to reach the Orange or Unhealthy for Sensitive Groups
category.

* WHERE...East central and central Minnesota.

* WHEN...From noon CDT to 9 PM CDT Friday.

* IMPACTS...Sensitive groups, such as people with lung disease
(including asthma), heart disease, children and older adults, and
people who are active outdoors, may experience health effects.

* ADDITIONAL DETAILS...Ground-level ozone is expected to be high
Friday afternoon in the Twin Cities metro area. Mostly sunny
skies, warm temperatures, and low humidity will provide a
favorable environment for two types of pollutants (volatile
organic compounds and nitrogen oxides) to react with sunlight in
the air to produce ground-level ozone. High/thin clouds will be
present, but enough solar radiation should make it to the surface
for ozone formation. Ozone levels are expected to reach alert
criteria around noon and will subside after sunset. Additional
alerts for ozone may be needed over the weekend if cloud cover is
less then expected.

Information: 
Sensitive groups such as people with lung disease (including
asthma), heart disease, children and older adults, and people who
are active outdoors should limit prolonged or heavy outdoor
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.
