HUDSON VALLEY, NY — Hot, humid and bad air. It seems as if the weather in the Hudson Valley is set on repeat.

It is going to be hot again in southern Westchester and parts of the mid-Hudson Valley.

There is a heat advisory in southern Westchester — heat index values up to 101 Friday — that is in effect until 8 p.m. Saturday.

In the mid-Hudson Valley, the heat advisory is for Dutchess, western Columbia and eastern Ulster counties. It's in effect from 11 a.m. to 7 p.m. Friday. You can expect heat index values between 95 and 100.

Health officials say to drink plenty of fluids and stay in air-conditioned rooms and out of the sun. If you have to be outside, do strenuous activities in the early morning or evening.

Along with the heat and humidity, which lead to the high heat indices, there is an air quality alert for Rockland and Westchester counties until 11 p.m. Friday.
