It's been hot in Florida for months. It is every summer.

However, Saturday's combination of extreme heat and humidity prompted the National Weather Service to issue a Heat Advisory for many cities.

In the statement issued Saturday morning, forecasters explain what a Heat Advisory means...

A Heat Advisory is issued when the combination of hot temperatures and high humidities creates heat indices of 108 degrees or higher. The heat index is a measure of how hot it feels when the effect of humidity combine with the temperature. High heat index values can create dangerously hot conditions where individuals may become critically exhausted if outdoors. Drink plenty of fluids, stay in an air-conditioning if possible, remain out of the sun, and check on relatives and neighbors who may be sensitive to heat related illnesses.
