Air Quality Alert
Issued: 11:33 AM MDT Mar. 24, 2019 – National Weather Service

... Ozone action day in effect for Sunday, March 24th, and Monday,
March 25th, 2019, for the Upper Green river basin ozone
nonattainment area...

The following message is transmitted at the request of the
air quality division of the Wyoming department of environmental
quality.

The air quality division has issued an ozone action day for
Sunday, March 24th, and Monday, March 25th, 2019, for the Upper
Green river basin ozone nonattainment area. An ozone action day is
issued when forecasted weather conditions are favorable for the
formation of ozone. Ozone appears to be elevated in the basin when
there is a presence of ozone-forming precursor emissions
including oxides of nitrogen and volatile organic compounds
coupled with meteorological conditions such as strong temperature
inversions, low winds, snow cover, and sunlight.

During the winter ozone season (january-march), everyone should
take actions to reduce precursor emissions and ground-level ozone
formation.

Ozone is an air pollutant that can cause respiratory distress
especially to children, the elderly, and people with existing
respiratory conditions such as asthma. People in these sensitive
groups should limit strenuous or extended outdoor activities,
especially in the afternoon and evening.
