Aug. 23 & 24: Excessive Heat Warning

August 22, 2023 -- An excessive heat warning is in effect for our area from August 23 - 24. Dangerously hot conditions with temperatures in the upper 90s with heat index values of 110 to 115 are expected Wednesday through Thursday evening, August 23 and 24. The National Weather Service recommends the following tips to stay safe during extreme heat:

  • Never leave children or pets in parked cars - even if the windows are cracked open.
  • Stay in air-conditioned spaces as much as you can. 
  • Stay out of the sun as much as possible and schedule any outdoor activities carefully.
  • Wear sunscreen when you're outside.
  • Drink plenty of water.
  • Check on friends and relatives who do not have air conditioning, especially the elderly.
  • Ensure pets have adequate water and be mindful to protect dogs' paws from excessively hot asphalt.

Extreme heat and humidity will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities. Young children and pets should never be left unattended in vehicles under any circumstances. Car interiors can reach lethal temperatures in a matter of minutes.
