Charleston summers are hot, and lately, we are experiencing more heat waves and the heat advisories associated with them. What is a heat wave? According to the American Red Cross, a heat wave is a prolonged period of excessive heat, generally 10 degrees or more above average, often combined with excessive humidity.
You will likely hear weather forecasters use these 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 forecasting to meet locally defined advisory criteria for 1 to 2 days (daytime highs= 100-105° Fahrenheit).
- Excessive Heat Warning – Heat Index values are forecasting to meet or exceed locally defined warning criteria for at least 2 days (daytime highs= 105-110° Fahrenheit).
What should you do BEFORE a heat wave comes?
- 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 to learn how to treat heat-related emergencies.
- Ensure that your animals’ needs for water and shade are met.
What should you do DURING a heat wave?
- Listen to a local radio station for critical updates.
- Never leave children or pets alone in enclosed vehicles.
- Stay hydrated by drinking plenty of fluids even if you do not feel thirsty. Avoid drinks with 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.
