Heat Safety Best Practices

Increased Risk of Heat Related Illness This Week

The current Heat Advisory for North Texas and eastern Central Texas has been extended through 8 PM Monday. High temperatures will range from 97 to 103, with heat index values up to 108. Continue practicing heat safety, especially during the hottest part of the day, by taking frequent breaks in the shade or A/C and staying hydrated.

Triple-digit temperatures will be common across North and Central Texas through at least the end of July. Afternoon heat index values will climb into the 100-115° range, with little relief at night as low temperatures remain in the upper 70s and lower 80s. If you’ll be spending time outdoors, plan for the heat by staying hydrated, taking frequent breaks, and checking on vulnerable family members, neighbors, and pets.

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.
