Air quality alert issued for Wednesday, heat wave expected

Rhode Island Department of Environmental Management has issued an air quality alert for Wednesday, June 20.

All RIPTA buses and trolleys, excluding special services, will be free Wednesday.

The DEM predicts air quality will reach unhealthy levels. A hot and humid air mass with west to southwest winds will lead to unhealthy conditions,

The poor air quality will be due to elevated ground-level ozone concentrations. Ozone is a major component of smog and is formed by the photochemical reaction of pollutants emitted by motor vehicles and industry, according to the DEM.

The DEM recommends Rhode Islanders cut down on pollution by carpooling, or taking advantage of free RIPTA service.

Due to the excessive heat forecast for the next two days, McDermott Pool in Warwick will have an additional open swim for all ages, from 1 to 3 p.m. tomorrow and Thursday.

Adult swim will end at 12:30 p.m. tomorrow and Thursday in order to allow all ages to cool off and enjoy the pool.

Rhode Island Emergency Management Agency told ABC6 they will be monitoring the weather. A representative from the EMA said the agency is advising residents to swim in one of the city's pools, or to cool off at library branches or air-conditioned community centers around the state.
