SAN ANTONIO (KTSA News) — The National Weather Service is extending the current Heat Advisory for San Antonio and much of the surrounding area through 8 p.m. Friday night.
Temperatures as high as 103 could trigger a Heat Index of around 105, or higher, in areas including New Braunfels, Austin and much of the I-35 Corridor.
Most of the Texas Hill Country will have no advisories or warnings, although daytime highs close to 100. This is prompting weather forecasters to urge caution for those spending significant time outdoors between the hours of 10 a.m. and 7 p.m.
NOTE: For those who have to work outside, it will be important to take appropriate precautions. The same can be said for those enjoying recreational activities outdoors.
Drinking plenty of water and taking frequent breaks, preferably in an air-conditioned environment, are strongly recommended.
Never leave young children or pets unattended in cars or trucks as the temperature can rise 20 degrees in as few as 10 minutes with the windows rolled up during the hottest times of the day.
