An ozone health advisory has been issued for Long Island Tuesday.

The air quality index is expected to reach 100 tomorrow. The pollutant of concern is ground-level ozone.

Suffolk County Health Commissioner Dr. James Tomarken advises that all residents — especially young children, seniors, those who exercise or are involved in strenuous outdoor work, and those with pre-existing respiratory or heart problems — limit strenuous outdoor activity.

The advisory is in effect from 11 a.m. to 11 p.m.

A heat advisory is also in effect both Tuesday and Wednesday, as the heat index is expected to peak at about 102 due to temperatures in the mid-90s and dewpoints in the lower 70s, according to the National Weather Service.

The heat advisory is in effect from 11 a.m. Tuesday to 9 p.m. Wednesday.

The weather service warned that high heat and humidity this week can cause illness and even death among at-risk populations who cannot stay cool. The heat and humidity may also cause heat stress during outdoor exertion or extended exposure.
