SHREVEPORT, LA (KSLA) - Every parish and county in the ArkLaTex will be under an Excessive Heat Warning until 9 p.m. Saturday. This means a prolonged period of dangerously hot temperatures and heat indices are expected to occur. With more dangerous heat in the forecast on Sunday, this Excessive Heat Warning could be extended further or a Heat Advisory could be issued.

On Saturday, temperatures are expected top out above 100 degrees. However, the humidity is going to make it feel even hotter. Max heat indices will likely be near or just above 110 degrees. Heat index values or feels-like temperatures could come close to 115 degrees in a few spots.

The heat index is what it 'feels-like' to your body when the humidity in the air doesn't allow you to cool off as efficiently as when the air is relatively dry.

When the heat indices reach 110 degrees it's very easy to suffer from either heat exhaustion or heat stroke. Anyone that is overcome by the heat this weekend should be moved inside to a cooler location. If you are concerned that someone is suffering from heat stroke they need immediate medical attention.

Here are some tips on how to protect yourself from becoming a victim of heat-related illnesses:

  • STAY HYDRATED: Drink plenty of water throughout the day.
  • LIMIT OUTDOOR ACTIVITY: Outdoor activities are discouraged, but if you have to do strenuous things like exercising or working in the yard they should be done very early in the morning or later in the evening.
  • DRESS APPROPRIATELY: Wear light-colored, loose-fitting clothing.
  • STAY COOL: Spend the day inside in air conditioning or well-circulated air.

On Friday, Shreveport's record high for July 20 was broken. The new record is 104 degrees. The original record was 101 degrees, which was set back in 2000.

With more triple-digit temperatures in the forecast, more record highs could be broken or tied this weekend.
