Meteorologists said temperatures will climb to near 100 degrees for most locations, and heat index values will reach as high as 109 degrees. The hottest temperatures will happen between 3 and 6 p.m.
People who must be outside during the advisory should take frequent breaks in the shade or air-conditioning and stay hydrated by drinking plenty of non-caffeinated and non-alcoholic beverages.
Similar weather is forecast for the remainder of the weekend as well. More advisories are expected.
What is a Heat Advisory?
A Heat Advisory is issued to warn the public of dangerously high "feels like temperatures."
When feels like temperatures hit 108 degrees or hotter, then a Heat Advisory is issued. The combination of high heat and humidity can be deadly or cause heat illness.
On a hot day, people sweat and their sweat evaporates, helping lower their internal body temperature.
When humidity is high, sweat does not evaporate as efficiently and it is harder to keep cool.
It is important to limit time outside during the afternoon and find air conditioning to stay cool.
