Staff Report

MIAMI, Fla. – Heat advisories and excessive heat warnings are affecting parts of South Florida, according to the National Weather Service (NWS).

Florida is expected to hover in the mid- to high 90s with heat indexes over 100 degrees forecast.

A heat wave is a prolonged period of excessive heat, generally 10 degrees or more above average, often combined with excessive humidity.

Floridians should be aware of other weather terms when a heat wave is predicted in your community:

Excessive Heat Watch – Conditions are favorable for an excessive heat event to meet or exceed local Excessive Heat Warning criteria in the next 24 to 72 hours. Heat Advisory – Heat Index values are forecasted to meet locally defined advisory criteria for 1 to 2 days (daytime highs= 100-105° Fahrenheit).

Excessive Heat Warning – Heat Index values are forecasted to meet or exceed locally defined warning criteria for at least 2 days (daytime highs= 105-110° Fahrenheit).

What to do during a heatwave warning:

• Listen to local weather forecasts and stay aware of upcoming temperature changes.

• Be aware of both the temperature and the heat index. The heat index is the temperature the body feels when the effects of heat and humidity are combined.

• Discuss heat safety precautions with members of your household. Have a plan for wherever you spend time – home, work, and school – and prepare for power outages.

• Check the contents of your emergency disaster kit in case a power outage occurs.

• Know those in your neighborhood who are elderly, young, sick, or overweight. They are more likely to become victims of excessive heat and may need help.

• If you do not have air conditioning, choose places you could go to for relief from the heat during the warmest part of the day (schools, libraries, theaters, malls).

• Be aware that people living in urban areas may be at greater risk from the effects of a prolonged heat wave than are people living in rural areas.

• Get trained in First Aid at your local Red Cross chapter to learn how to treat heat-related emergencies.

• Ensure that your animals’ needs for water and shade are met.

• Listen to a NOAA Weather Radio for critical updates from the National Weather Service (NWS).

• Never leave children or pets alone in enclosed vehicles.

• Stay hydrated by drinking plenty of fluids even if you do not feel thirsty. Avoid drinking caffeine or alcohol.

• Eat small meals and eat more often.

• Avoid extreme temperature changes.

• Wear loose-fitting, lightweight, light-colored clothing. Avoid dark colors because they absorb the sun’s rays.

• Slow down, stay indoors and avoid strenuous exercise during the hottest part of the day.

• Postpone outdoor games and activities.

• Use a buddy system when working in excessive heat.

• Take frequent breaks if you must work outdoors.

• Check on family, friends and neighbors who do not have air conditioning, who spend much of their time alone or who are more likely to be affected by the heat.

• Check on your animals frequently to ensure that they are not suffering from the heat.
