People are being warned to stay in cool places and avoid unnecessary outdoor exercise because heat is going to drive up ozone levels in much of New York.
State health and environmental officials say the combination of heat and smog is expected to push ozone levels above acceptable limits Friday in the New York metropolitan area, lower Hudson Valley and western New York.
The air quality advisory is in effect from 11 a.m. to 11 p.m.
Children, people doing hard outside work and those with respiratory problems are at particular risk.
