Extreme Heat Safety

An Extreme Heat Warning remains in effect through 8pm Wednesday for North Texas, where afternoon high temperatures up to 108 degrees can be expected. A Heat Advisory remains in effect through 8pm Tuesday across Central Texas, where afternoon heat indices up to 109 degrees can be expected. Remember to drink plenty of water, to take frequent breaks in the shade or A/C, and to look before you lock your vehicle!

Sunny and dry conditions will continue, with widespread triple-digit temperatures across North and Central Texas expected into the evening tonight. Remember to drink plenty of water, take frequent breaks in shaded or air-conditioned areas, and NEVER leave kids or pets unattended in vehicles!

Unseasonably hot temperatures will continue, with heat indices consistently in the 105-109 range. With little to no rain chances upcoming, hot and dry conditions are not expected to ease anytime soon.

After a wet June, the region entered a dry period. Most locations have seen below-normal rainfall over the last 30 days (indicated by the yellow to red colors on the map). Drought conditions will likely worsen IF we don't see significant rainfall in the weeks ahead.

Extreme heat is expected this week. Everyone is at risk from the dangers of extreme heat, but these groups are more vulnerable than most. Ensure that your loved ones and neighbors are safe from the heat and remain Weather-Ready. weather.gov/safety/heat-during
