Cuero Online News | Aug 20, 2026
A prolonged Heat Advisory has been issued by the National Weather Service Austin/San Antonio, effective from August 20 at 1:29 a.m. CDT through Sunday, August 23 at 7:00 p.m. CDT. The advisory covers the northern Hill Country, the I‑35 Corridor, and the Coastal Plains, including communities such as Austin, San Antonio, New Braunfels, Seguin, Gonzales, and Cuero.
Forecasters warn that temperatures may reach 104°F, with heat index values climbing as high as 112°F during the afternoon and early evening hours. The combination of extreme heat and high humidity significantly increases the risk of heat exhaustion and heat stroke, especially for individuals working outdoors or spending extended time in direct sunlight.
Regional Impact
The region has already experienced multiple days of triple‑digit temperatures, and emergency departments across Central Texas have reported elevated numbers of heat‑related illnesses this summer. Vulnerable populations include older adults, infants, young children, pregnant individuals, and those with chronic medical conditions.
Safety Recommendations
The National Weather Service urges residents to take the following precautions:
- Drink plenty of water throughout the day.
- Stay in air‑conditioned environments whenever possible.
- Avoid direct sun exposure during peak heat hours.
- Wear lightweight, loose‑fitting clothing.
- Limit strenuous outdoor activity to early morning or evening.
- Check on neighbors, relatives, and vulnerable individuals.
- Move anyone experiencing heat illness to a cool, shaded location immediately.
- Heat stroke is a medical emergency — call 911.
Important Reminder for Outdoor Workers
Outdoor workers—including construction crews, road workers, landscapers, agricultural workers, and utility personnel—face the highest risk during this advisory. OSHA recommends:
- Scheduling frequent rest breaks in shaded or cooled areas.
- Ensuring workers have constant access to water.
- Rotating strenuous tasks to reduce prolonged exposure.
- Monitoring workers for signs of heat exhaustion, such as dizziness, nausea, heavy sweating, headache, or confusion.
Employers are encouraged to adjust schedules when possible and reinforce heat‑safety protocols to protect their crews.
Community Awareness
Local officials and emergency responders urge residents to remain vigilant throughout the advisory period. With temperatures expected to remain dangerously high through Sunday evening, taking preventive measures can significantly reduce the risk of heat‑related emergencies.
