Smoke from wildfires in Ontario is expected to continue to make its way over Maine Wednesday, and the particle pollution is making the skies hazy. The Maine Department of Environmental Protection says that the densest portion of the plume is remaining aloft with lower level particle pollution at the surface. Officials have categorized the particle pollution as “moderate.” Some of the largest wildfires are burning in west-central Ontario, and those fires are burning through thick forests, releasing a massive amount of smoke.
