An air quality alert remains in effect for the entire state of New York. It comes with another day of 90-plus degree weather.

Ozone levels increase when auto and industrial emissions are impacted by sunlight.

As electricity demand increases in the hot weather, Rochester Gas & Electric reported sporadic power failures in Monroe County.

NYSEG also reported no power in parts of Ontario, Seneca, Wayne and Yates counties.

Outside Rochester, other parts of the east saw temperatures rise to 100 degrees, including New Jersey and Washington, D.C.

The weather forced some commuter trains in the east to slow down because the extreme heat can cause rails to bend under pressure from a passing train.
