Increased Risk of Heat Related Illness This Week

A Heat Advisory is in Effect for North Texas and eastern Central Texas through Monday evening. High temperatures in the upper 90s to around 103, along with heat index values up to 107, can be expected in the advisory area. Remember to stay hydrated and limit time spent outdoors.

Triple digit high temperatures will be common mid to late week, along with heat index values climbing to near 110 in some areas during the afternoon. Remember to stay hydrated, take frequent breaks if working outdoors, and protect your pets by providing plenty of water and keeping them off hot pavement!

Temperatures will return to more seasonable values this weekend with the arrival of a weak summer cold front. It will still be plenty warm, however, with highs mostly in the mid to upper 90s expected on Sunday.

With summer heat in full swing across our area, take a moment to review these heat safety best practices. Heat related illness and death is preventable as long as you know how to protect yourself by staying cool and hydrated.

Dangerous heat is expected this week, which will increase the risk of heat related illnesses. Make sure you know the signs of heat exhaustion and heat stroke in order to protect yourself and others from the heat.
