Heat Safety Best Practices

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.

The Heat Advisory has been extended through Tuesday evening and expanded to include Robertson County. Actual temperatures will be between 97 and 103 degrees with heat index values up to 109 degrees within the advisory. Ensure you practice heat safety by limiting time spent outdoors and drinking plenty of water.

Triple digit heat is expected throughout the week. Humidity will increase over the next few days, with heat index values climbing to 105-115 degrees for much of the area late this week. Heat advisories and/or an Extreme Heat Warning will likely be needed through the end of the week.

A weak summer cold front will move through the area over the weekend, resulting in a slight "cool" down for the region. High temperatures will drop a few degrees, returning to the mid to upper 90s on Sunday behind the front. Drier air will also move in behind the front, which will result in slightly cooler mornings in the 70s.

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.
