Extreme heat returns to the St. Louis region

ST. LOUIS – Another round of heat will impact the St. Louis region. An Excessive Heat Warning and Heat Advisory are in effect through 10 p.m. Saturday.

Temperatures will climb to the upper 90°s both days. Southerly winds will continue to bring in Gulf of Mexico moisture, meaning dewpoints will be in the low to mid 70°s. When combining these high temperatures and high dewpoints, heat index values will reach dangerous levels.

Peak heating will occur between 1 p.m. and 6 p.m. both days. Afternoon heat index readings will be in the 105° to 115° degree range.

Heat is one of the leading weather-related killers in the United States. Take extra precautions if you’re going to be out in this extreme heat.

Over the 30-year average, heat is the leading cause of weather-related fatalities in the U.S. In 2017, heat was the 2nd leading cause of fatalities (behind flooding).

Heat safety tips:

  • Drink plenty of water and avoid caffeine and alcohol
  • Take breaks in the shade or inside as often as possible
  • Wear lightweight, light-colored clothing which will reflect sunlight rather than absorb it
  • Never leave kids or pets unattended in vehicles – LOOK before you LOCK
  • Check up with the elderly, sick and those without AC (if you’re without AC, you should get to a place that has AC)
  • Know the warning signs of heat exhaustion and heat stroke
