A heat advisory went into effect at 11 a.m. Tuesday and will remain through 9 p.m. Wednesday as the temperature is expected to feel over 100 degrees during the warmest parts of the days, according to the National Weather Service.

The high temperature for both Tuesday and Wednesday is expected to be around 90 degrees and the heat index value will be between 95 and 104, according to the NWS.

A heat advisory is issued when the combination of heat and humidity is expected to make it feel like it is 95 to 99 degrees for two or more consecutive days or 100 to 104 degrees for any length of time.

“Extreme heat can cause illness and death among at-risk population who cannot stay cool,” the NWS advisory says. “The heat and humidity may cause heat stress during outdoor exertion or extended exposure.”

The heat wave is expected to break Friday with a high temperature in the mid-70s.

The State Department of Environmental Conservation has also issued an air quality health advisory, which is in effect until 11 p.m. Tuesday. Air quality levels in outdoor air are predicted to be greater than an air quality index of 100 for ozone. Due to elevated pollution levels, the State Department of Health urges people to limit strenuous outdoor physical activity. Click here for more information.
