Smoke from wildfires raging on the west coast made its way to Massachusetts on Monday, casting a thick haze over parts of the state and prompting officials to warn of potentially “unhealthy” air quality.

The Massachusetts Department of Environmental Protection said in a tweet that plumes of smoke from the fires is “again causing fine particle levels to elevate into Unhealthy for Sensitive Groups range today in all MA counties except Plymouth, Bristol & the Cape & Islands.”

Fires are burning in northern California, southern Oregon, Montana, Washington, and Canada.
