Lake Charles, Louisiana – Above-normal temperatures are predicted to begin in Southwest Louisiana today and persist through the upcoming week. Forecasts indicate that daytime highs will range from the upper 80s to low 90s degrees Fahrenheit, with heat indices—the measure of how hot it feels when humidity is factored in—expected to climb into the upper 90s and even low 100s in some locations.

While these temperatures are not expected to break longstanding records, meteorologists note they will fall just a few degrees short. The heat risk is not only about individual daily highs but also about the prolonged exposure to elevated temperatures, which can increase the potential for heat-related illnesses.

Understanding Heat Indices and Heat Risk

Heat index is a term used to describe the combined effect of temperature and humidity on the human body. When both values are high, the body has a harder time cooling itself, making it feel hotter than the actual air temperature. For example, an air temperature of 90 degrees can feel closer to 100 degrees if the humidity is high.

The National Weather Service uses a heat risk scale to help the public understand how dangerous the conditions could become. For today, only minor impacts are anticipated, which means most people can go about their activities with basic precautions, such as staying hydrated and taking breaks in the shade. However, starting tomorrow and continuing for at least the next seven days, the area is expected to experience moderate heat risk levels. Vulnerable populations such as the elderly, young children, and those with existing health conditions should take hot weather precautions.

Health and Safety Tips During Elevated Heat

Some tips and safety measures as the heat intensifies:

  • Stay Hydrated: Drink plenty of water, even if you do not feel thirsty. Avoid drinks with caffeine or alcohol, as they may contribute to dehydration.
  • Limit Outdoor Activities: Try to schedule strenuous activities during the cooler parts of the day, such as early morning or late evening.
  • Seek Air Conditioning: Spend as much time as possible in air-conditioned buildings. Public spaces like libraries and shopping centers can provide relief if home cooling is unavailable.
  • Watch for Symptoms: Heat-related illnesses can include heat exhaustion and heat stroke. Symptoms such as dizziness, rapid pulse, headache, or confusion require immediate attention.
  • Check on Others: Neighbors, elderly family members, and pets are particularly at risk during extreme heat. Ensure they have access to cool environments and adequate hydration.
