The Iowa DNR is issuing an Air Quality Alert for the eastern half
of Iowa through 11am Monday.

Monitors near Dubuque, Cedar Rapids, Iowa City, Clinton,
Davenport, and Muscatine are currently reporting hourly fine
particulates at concentrations the EPA considers unhealthy, due to
smoke. At this level, sensitive groups of people, as well as the
general public may experience health effects. Fine particulates
near or above EPA health standards are expected to persist and
spread westward Monday.

The DNR recommends that sensitive people avoid long or intense
outdoor activities, and consider rescheduling or moving activities
indoors. Sensitive groups include people with respiratory illness
or heart disease, older adults, children, teenagers, pregnant
women, and outdoor workers. Everyone else should reduce long or
intense activities and take more breaks during outdoor activities.
