...POOR AIR QUALITY IN THE MID-ATLANTIC THROUGH FRIDAY DUE TO
CANADIAN WILDFIRES...

Due to Canadian wildfires, smoke is prevalent in the Mid-
Atlantic region, including the greater Baltimore and Washington
metropolitan areas. Under northerly winds, smoke will continue to
be pushed south over our area. Thicker smoke will continue to
overspread portions of the area, resulting in poor air quality
and visibility potentially less than 1 mile. Some improvement is
likely through the day, but the smoke likely will continue to
affect the area at times until a front on Friday potentially
brings some reprieve to fine particle concentrations.

Depending on your location, Air Quality will vary, with much of
the area either Code Orange or Code Red through the day today.
There is a Code Purple Air Quality Alert for the District of
Columbia.

A Code Orange Air Quality Alert means that air pollution
concentrations within the region are unhealthy for sensitive
groups. Sensitive groups include children, people with heart or
lung disease, older adults, pregnant people, and those that spend
a lot of time outdoors.

Some areas may see Code Red, which means “unhealthy for the
general population.” If you are under a Code Red Air Quality
Alert, everyone should keep outdoor activities light and short.
For those people in sensitive groups, consider moving all
activities indoors.

A Code Purple Air Quality Alert means that everyone may
experience more serious heath effects and should avoid outdoor
activities, especially individuals with heart and breathing
ailments, children, and older adults.

The effects of air pollution on people can be minimized by
avoiding strenuous outdoor activity or exercising indoors. Go
indoors if you have symptoms.

Be aware of your air quality, which you can track here:

Air quality monitoring and forecasts are done by the states. The
National Weather Service helps to disseminate these air quality
forecasts.
