wsiThe National Weather Service has issued a heat advisory from 1 p.m. today, Friday, July 22, until 7 p.m. Saturday, July 23, for most of North Alabama and Southern Middle Tennessee.

Afternoon temperatures will range between 95 to 99, with heat index values between 105 and 108. Temperatures will be higher in asphalt roadways and concrete-covered areas where there is no shade and no breeze.

Stay hydrated!

The combination of hot temperatures and high humidity levels will be dangerous  for those spending time outdoors or in a facility with no air conditioning.

Take extra precautions if you work or spend time outside.  When possible, reschedule strenuous activities to early morning or evening.

Know the signs and symptoms of heat exhaustion and heat stroke: Symptoms range in severity from mild heat cramps to heat exhaustion to potentially life-threatening heatstroke. Heat exhaustion can begin suddenly, usually after working or playing in the heat, perspiring heavily or being dehydrated.

Heat exhaustion signs and symptoms include:

  • Faintness or dizziness
  • Nausea or vomiting
  • Heavy sweating often accompanied by cold, clammy skin
  • Weak, rapid pulse
  • Pale or flushed face
  • Muscle cramps
  • Headache
  • Weakness or fatigue

If you experience these symptoms, seek immediate medical assistance by calling 911!

Wear light weight and loose fitting clothing when possible and drink plenty of water.

Check up on relatives and neighbors.  Absolutely do not leave children and poets unattended in vehicles!

Heat kills by pushing the human body beyond its limits. In extreme heat and high humidity, evaporation is slowed and the body must work extra hard to maintain a normal temperature.

Most heat disorders occur because the victim has been overexposed to heat or has over-exercised for his or her age and physical condition. Older adults, young children and those who are sick or overweight are more likely to succumb to extreme heat.

Conditions that can induce heat-related illnesses include stagnant atmospheric conditions and poor air quality. Consequently, people living in urban areas may be at greater risk from the effects of a prolonged heat wave than those living in rural areas. Also, asphalt and concrete store heat longer and gradually release heat at night, which can produce higher nighttime temperatures known as the “urban heat island effect.”
