The sun has returned, and with it will come extreme heat.
A Heat Advisory has been issued for the Hudson Valley, Fairfield County and New York City from 10 a.m. Sunday until 8 p.m. Monday, Aug. 6.
Sunday will see bright sunshine with a high in the low-90s, but it will feel like it's closer to 100 degrees, as the heat index - a combination of the temperature and humidity - will be in the upper-90s.
Monday will also be sunny and hot, with a high around 92.
There's a good chance for a heat wave -- defined as three days or more of a high temperature of 90 above -- as Tuesday's high could hit 90 degrees on a mostly sunny day. There is a chance of showers and thunderstorms Tuesday afternoon and evening.
A Heat Advisory means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible.
Extreme heat can cause illness and death among at-risk population who cannot stay cool, the National Weather Service warns.
The heat and humidity may cause heat stress during outdoor exertion or extended exposure.
