PORTLAND (AP) – The state Department of Environmental Protection warned that unhealthy ozone levels would continue along the coast on Friday, a day after temperatures nudged toward 90 in parts of Maine.

Pollution combined Thursday with sunny skies and hot temperatures and along with southern winds pushed ground-level ozone concentrations to uncomfortable and unhealthy levels, the Maine DEP said.

“The humidity is up and the pollution is definitely flowing in,” said Eric Sinsabaugh of the National Weather Service.

Sensitive individuals, including people with respiratory problems or heart disease, children and the elderly, were warned to stay indoors and avoid strenuous activity like jogging.

Relief was on the way in the form of a weather front that was expected to arrive Friday afternoon with scattered showers and thundershowers, followed by drier, cooler air, Sinsabaugh said.
