It has been extremely hot the past several days, and hot temperatures – in the 90s – are also predicted again this coming week, causing the National Weather Service to issue advisories. We’ve seen close to two dozen days this summer with temperatures near 90 degrees or higher.
Summer heat increases the risk of heat related incidents. The Centers for Disease Control and Prevention (CDC) reports more than 600 people in the United States are killed by extreme heat every year. The agency also states heat-related deaths and illnesses are preventable.
The American Red Cross of Tennessee Region warns that excessive heat has caused more deaths than all other weather events, including floods in recent years. A heat wave is a prolonged period of excessive heat, generally 10 degrees or more above average, often combined with excessive humidity.
Tennesseans should be aware of 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.
It’s good to enjoy the summer sunshine with family and friends, but use common sense and know when it’s time to take a rest or go inside for your own safety.
