A heat advisory is in effect again across Northeast Ohio — until 8 p.m. Thursday — according to the National Weather Service.
Heat index values are expected to reach as high as 102 degrees.
The region’s hot temperatures also have triggered an ozone alert through Thursday for eight counties: Summit, Portage, Medina, Cuyahoga, Lake, Lorain, Geauga and Ashtabula counties.
Ozone is formed when hydrocarbons combine with nitrogen oxides in direct sunlight. The pollutants come from industry, vehicles and coal-burning power plants.
It can cause breathing problems for children, the elderly and asthmatics. Those groups may want to curtail strenuous outdoor activity.
