(Indianapolis, IN) - An air quality action day is in effect for LaPorte and surrounding counties.

The advisory was issued by the Indiana Department of Environmental Management. Hot and humid temperatures are expected to increase ozone levels to where some people could have more trouble breathing.

Officials say, children, the elderly, and people with lung or heart conditions should reduce or avoid exertion and heavy work outdoors. Officials say people should also walk, bike or work from home if possible to reduce vehicle emissions.
