The hazy, thick smoke from Canadian wildfires that has gripped much of the north and east coast of the United States is moving into Alabama, according to the Birmingham office of the National Weather Service.

“We’ll start seeing some hazy conditions today as northerly flow from Canada at 10 to 15k feet will begin to set in across the Southeast,” the office tweeted Wednesday morning. “Although not as bad as to our east and northeast, we’ll see some affects from wildfire smoke.”

CBS 42 meteorologist Dave Nussbaum tweeted a photo of a hazy sunrise from Sumiton on Wednesday morning that may have been affected by the Canadian wildfire smoke:

The smoke has impacted air quality from New York to the northeast tip of North Carolina, with images showing brown, hazy smoke that appeared to erase parts the New York City skyline:

As of 3 p.m. Wednesday, the air quality index was 105 in Huntsville, which is categorized as “unhealthy for sensitive groups.” Those groups include people with lung diseases such as asthma, children and teens, older adults and people who are active outdoors for more than six hours a day.

Those groups are advised to choose less strenuous activities, shorten the time they are outdoors and only be active when the air quality has improved.

The index displayed moderate ratings for Birmingham and good for Mobile.

The Alabama Department of Environmental Management, which monitors and forecasts air quality in Alabama, is predicting air quality in the moderate range for Thursday in Birmingham and Huntsville. Air quality is forecast in the good range for Mobile on Thursday.
