Canadian Wildfires Prompts Air Quality Advisory for Maine

24-hour particle pollution concentrations are expected to reach Moderate levels Tuesday late afternoon into Wednesday according to the Maine Department of Environmental Protection (DEP). Several fires have been burning for more than a day in Nova Scotia. The smoke has moved into the Gulf of Maine where winds from a small High-Pressure system combined with an afternoon sea breeze are expected to bring the smoke ashore in Maine during the afternoon to evening hours. The plume of smoke is expected to move inland overnight. While there could be a few hours with higher levels of particle pollution it is expected that the 24-hour average will not rise above the moderate range on the Air Quality Index. Skies will be hazy; visibility may be reduced and the odor of smoke is likely to be apparent.
