Here is an update from the National Weather Service in New Orleans concerning the heat threats for today and the remainder of the week.

Overview:

WHAT:
Excessive Heat Warning in effect today.
Excessive Heat Watch has been issued for Wednesday and the dangerous heat conditions are expected to continue into the weekend. Heat index values of 110-120°F are expected today and will be possible Wednesday through Saturday.


WHEN:
Excessive Heat Warning: 10AM – 8PM Tuesday.
Excessive Heat Watch: 10AM – 8PM Wednesday
More Heat products are likely to continue through the remainder of the week.

WHERE:
All of southeast LA and coastal/southwest MS

CONFIDENCE:
High confidence of dangerous heat indices Today. Confidence is a little lower on Wednesday as there is the possibility of another thunderstorm complex working south-southeast through MS and towards coastal MS and southwest AL. This would lead to increasing cloud cover and possibly rain. Even if that occurs it may still be late enough in the day allowing dangerous heat conditions to develop ahead of this complex. Confidence is increasing for excessive heat to continue Thursday and into the weekend.


Impacts:
The combination of afternoon heat index readings above 110 degrees and morning lows remaining well above normal will provide little if any relief for the body to cool for those without access to air conditioning or cooling centers.
Heat illness can occur quickly. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstance.
