Heat Safety Best Practices

Increased Risk of Heat Related Illness This Week

Much of North and Central Texas remains under a Heat Advisory through this evening. Triple-digit temperatures and heat index values ranging from 105 to 110 will be common across the region. Please ensure you, your loved ones, and your pets stay hydrated and cool, and try to limit your time outdoors.

A weak cold front will bring a slight chance of storms late Friday and Saturday, followed by more seasonable temperatures late Saturday and Sunday. A few storms may produce gusty downburst winds. Otherwise, Friday will be another triple digit temperature day ahead of the front.

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.
