Northerly winds continue to push smoke from wildfires out west and in Canada into Iowa, prompting officials to issue a statewide air quality alert.

“The most persistent smoke had been in northwest portions of the state. Until the plume clears around noon on Monday, fine particulate levels over the EPA health standard are expected, and sensitive groups should take precautions,” according to a statement issued Sunday by the Iowa Department of Natural Resources.

Sensitive groups include the elderly, those with respiratory or heart disease and children, who should limit prolonged outdoor exertion until air quality conditions improve.
