A DEP Air Quality Alert is in Effect for Sunday Along the Coast of Maine

Ground-level ozone concentrations will be climbing in Maine late Saturday evening, dropping off overnight then building up again on Sunday along the coast of Maine from Kittery through Acadia NP and are expected to reach unhealthy levels on Sunday according to the Maine Department of Environmental Protection (DEP). Ozone levels have been at or near unhealthy levels in southern New England for days. Winds Saturday evening will turn toward Maine in the Gulf of Maine continuing into Sunday. This will allow transport of ozone and its precursors from upwind sources such as southern New England and beyond to Maine. Meanwhile, particle pollution levels will likely be in the moderate range in southern portions of Maine.
