A heat advisory is issued by the National Weather Service when the heat index is expected to rise above 108.

The current forecast for Saturday in Orlando is 98, but it has the potential to reach 99 degrees without the humidity. While one degree doesn’t make that much of a difference, if the temperature does soar to 99 degrees or hotter at the Orlando International Airport, it will be the hottest day since 2015.

In Seminole County, officials are preparing to activate cooling centers to provide relief and planning to activate the extreme weather plan in place for high heat.

The National Weather Service cautioned residents of advisory areas to drink plenty of fluids and stay out of the sun, as the hot temperatures and high humidity could cause heat-related illnesses.

According to fire rescue officials, extreme heat and humidity can cause sickness and even death — so Florida residents should be cautious.
