DESCRIPTION: The Maine Department of Environmental Protection's Bureau of Air Quality has issued an Air Quality Alert for particle pollution until 11 PM EDT Monday. Through tonight particle pollution levels are expected to rise into the Unhealthy range for our Northern region and Unhealthy for Sensitive Groups range for the Western Mountains and Western Interior regions. This is due to smoke from wildfires in Canada that will be brought to Maine. Particle Pollution levels are expected to be in the Unhealthy for Sensitive Groups range statewide on Monday. A cold front will slowly push that smoke plume south through Maine on Monday. The front will likely concentrate smoke ahead of it. 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, the elderly, those with pre-existing respiratory problems such as asthma, those with heart disease and anyone who is working hard 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 www.maine.gov/dep/air/aqforecast.

Snow is precipitation taking the form of ice crystals. Each ice crystal, or snowflake,
has unique characteristics, but all of them grow in a hexagonal structure.
Snowfall can last for sustained periods of time and result in significant buildup
of snow on the ground.
On the earth's surface, snow starts out light and powdery, but as it begins to melt
it tends to become more granular, producing small bits of ice which have the consistency of
sand. After several cycles of melting and freezing, snow can become very dense
and ice-like, commonly known as snow pack.

Next Topic: Wall Clouds
Stratus clouds are similar to altostratus clouds, but form at a
lower altitude and are identified by their fog-like appearance, lacking the
distinguishing features of most clouds.
Stratus clouds are wider than most clouds, and their base has a smooth, uniform
look which is lighter in color than a nimbostratus cloud.
The presence of a stratus cloud indicates the possibility of minor precipitation,
such as drizzle, but heavier precipitation does not typically arrive in the form
of a stratus cloud.
