Air Quality Alert

Air Quality Alert issued July 2 at 3:15PM EDT by NWS Caribou ME
Jul 2, 3:15 PM Jul 6, 12:00 AM
The Maine Department of Environmental Protection's Bureau of Air
Quality has issued an Air Quality Alert for particle pollution from
midnight tonight to midnight EDT Sunday night.

Particle pollution levels are expected to rise into the Unhealthy for
Sensitive Groups range periodically during the weekend. People are
advised to follow the health message if visibility is poor or they
can smell smoke.

The Maine Department of Environmental Protection recommends that
individuals consider limiting strenuous outdoor physical activity to
reduce the risk of adverse health effects. People who may be
especially sensitive to the effects of elevated levels of pollutants
include the very young, older adults, those who work outdoors, those
with pre-existing respiratory problems such as asthma, and those
with heart disease. It is okay to be active outdoors. But if you
experience symptoms such as shortness of breath, coughing, throat
irritation or an uncomfortable sensation in your chest, please
consider limiting the intensity and duration of your outdoor
activities.

A toll free air quality hotline has been established so Maine
residents can stay informed on the air quality situations. The toll
free number is: 1-800-223-1196.

Additionally the Maine Department of Environmental Protection has
the air quality forecast available on the web at
