Heat advisory warning

Published 10:32 am Thursday, June 16, 2022

WHAT: Potentially dangerous heat conditions with heat index values of 108-112 degrees.

 WHEN:  Each day from mid morning through early evening through just about the entire 7-day forecast.

WHERE:  All of coastal and southwest Mississippi and most of southeast Louisiana except along the coast.

CONFIDENCE:  We are confident hot temperatures and high humidity will occur today through Saturday and could quickly lead to heat illness if precautions aren’t taken. Slightly drier air may keep peak heat index values in the 100-105 degree range Sunday through Tuesday. Nonetheless, it will still be very hot with high temperatures in the mid to upper 90s.


  • Heat index readings will climb above 108 degrees for multiple hours this afternoon.

  • Heat index readings above 112 degrees are possible in a few spots Friday and Saturday afternoons.

  • Prolonged Heat Wave: The combination of triple-digit afternoon heat index readings and morning lows remaining well above normal for an extended period will provide little if any relief for the body to cool for those without access to air conditioning or cooling centers.
