Houston, TX, July 22, 2026 —

An extreme heat warning has been issued for Southeast Texas, including the major metropolitan area of Houston, scheduled to take effect on Wednesday. Residents are advised to prepare for dangerously high temperatures.

Wearing lightweight, light-colored clothing is also recommended for those who must be outdoors.

Further details regarding the specific timing of the warning and the expected temperature ranges are expected to be released by the National Weather Service. The public is encouraged to monitor local weather forecasts for the most up-to-date information and advisories as Wednesday approaches.
