Saskatchewan and Manitoba is moving south across northwest Minnesota
on Wednesday. The smoke will remain over the northwest part of the

central portions of the state Thursday morning, and by Thursday

with improvement in fine particle levels below the alert threshold

Reduce vehicle trips and vehicle idling as much as possible.
Keep windows closed overnight to prevent smoke from getting indoors.
