Tennessee is set to experience a sweltering Tuesday as the heat index, a measure of how hot it feels when humidity is combined with air temperature, is expected to soar to a potentially dangerous 111° in Memphis, Southaven, and surrounding areas. This intense heatwave has prompted the National Weather Service (NWS) to issue an Extreme Heat Warning for a significant portion of the Mid-South, including West Tennessee, North Mississippi, and East Arkansas.

The Extreme Heat Warning will be in effect from 11 a.m. to 8 p.m. CDT, cautioning residents and visitors alike about the heightened risk of heat-related illnesses. The combination of high temperatures and oppressive humidity can quickly lead to heat exhaustion or, more seriously, heatstroke if proper precautions are not taken.

The NWS urges everyone in the affected areas to take the following steps to stay safe during this period of extreme heat:

Drink plenty of water throughout the day, even if you don't feel thirsty. Avoid sugary drinks and alcohol, as they can dehydrate you.

Spend as much time as possible in air-conditioned environments. If you don't have air conditioning at home, consider visiting a shopping mall, library, or community center.

Avoid strenuous activities outdoors, especially during the hottest part of the day (11 a.m. to 4 p.m.). If you must be outside, take frequent breaks in the shade.

Wear Light-Colored, Loose-Fitting Clothing: Light colors reflect sunlight and loose-fitting clothing allows for better air circulation, helping to keep you cooler.

Never Leave Children or Pets in Cars: Even on a mild day, the temperature inside a car can quickly rise to dangerous levels, posing a serious threat to children and pets.

Check on Vulnerable Individuals: Elderly individuals, young children, and people with chronic health conditions are particularly vulnerable to heat-related illnesses. Check on your neighbors, friends, and family members to ensure they are staying safe.

The extreme heat may also impact travel, particularly along major transportation routes such as I-55, I-40, and US 61. Motorists are advised to be prepared for potential delays and to ensure their vehicles are properly maintained. Carry extra water and snacks in case of breakdowns or traffic congestion.

Recognizing the signs of heat exhaustion and heatstroke is crucial during periods of extreme heat. Heat exhaustion symptoms include heavy sweating, weakness, dizziness, headache, nausea, and muscle cramps. If you experience these symptoms, move to a cool place, drink water, and rest. Heatstroke is a more serious condition characterized by a high body temperature (103°F or higher), confusion, seizures, and loss of consciousness. If you suspect someone is suffering from heatstroke, call 911 immediately.

As Tennessee and the Mid-South brace for this intense heatwave, it is essential to prioritize safety and take necessary precautions to protect yourself and those around you. Stay informed about the latest weather updates and heed the advice of the National Weather Service to minimize the risk of heat-related illnesses.
