"I don't think you can escape it from up by Boston all the way down to Washington, DC," Champion said.
You may be able to smell smoke in the air depending on where you live. There may also be a bit of haze at times.

Nova Scotia Premier Tim Houston announced the province would be banning all travel and activity in all wooded areas as of 4 p.m. local time. The ban applies to all forestry, mining, hunting, fishing, hiking, camping, off-road vehicle driving and all commercial activity on government lands.
"We're in a very serious situation in this province, and we need to take the steps that we can to protect Nova Scotia," he told a news conference via a video call from Shelburne, Nova Scotia, where the province's largest wildfire has been burning since the weekend.
"I wanted to get a sense of the damage here," the premier said. "It's extensive. It's heartbreaking."
