1. Do you know what a heat advisory means?

In regions of low humidity, the most common human response to extreme heat is dehydration. Exposed to direct sunlight and temperatures in excess of 90 degrees, a human can lose as much as half a gallon of water every ten minutes, and this dehydration can seriously interfere with one's internal thermostat.

2. How will you be warned?

If you are in the peak summer months, and the temperature and/or humidity has been unusually high for several days, anticipate an extreme heat emergency situation. Keep an eye on The Weather Channel to track the heat index and to get information on excessive heat potential. 

Although the threshold criteria may vary depending on the location, two kinds of alerts are generally issued.

Heat Advisory

Issued when the heat, or combination of heat and humidity, is expected to become an inconvenience for much of the population, and a problem for some.

Excessive Heat Warning

Issued when the heat, or combination of heat and humidity, is expected to be dangerous for a large portion of the population.
