San Antonio Prepares for Tonight’s Freezing Chill
San Antonio residents are advised to prepare for significantly cold temperatures expected tonight as a strong winter front moves through Texas. Forecasts indicate a hard freeze, urging immediate precautions to protect homes, pets, and loved ones from dangerously low temperatures.
Understanding the Forecast
Temperatures across the San Antonio area are predicted to plummet well below freezing tonight, likely dipping into the low 20s Fahrenheit. Gusty winds will make wind chill values feel even colder, creating hazardous conditions. Frigid temperatures will persist for several hours overnight, with a gradual warming trend anticipated by late morning tomorrow, though conditions will remain brisk.
Key Cold Weather Precautions: The 4 Ps
Protecting your property and ensuring safety during a freeze is paramount. Follow these essential guidelines:
- Pipes: Insulate exposed outdoor pipes and cover outdoor spigots. It’s highly recommended to drip faucets slowly, especially those on exterior walls, to prevent pipes from freezing and bursting. Know where your main water shut-off valve is located in case a pipe does burst.
- Plants: Bring sensitive potted plants indoors or move them to a sheltered area like a garage. For plants that cannot be moved, cover them with blankets, burlap, or frost cloths, ensuring the covering extends to the ground to trap residual heat.
- Pets: All pets should be brought inside during freezing temperatures. If keeping pets outdoors is unavoidable, ensure they have adequate shelter that is dry, elevated, and insulated, with plenty of warm bedding. Check water bowls frequently to prevent freezing.
- People: Dress in layers if you must go outside. Minimize outdoor exposure, especially for children and the elderly. Check on elderly neighbors or those who may need assistance to ensure they are warm and safe. Stay informed about warming centers if you lose power or have insufficient heating.
Additional Safety Measures and What’s Next
Beyond the “4 Ps,” remember general winter safety. If using space heaters, ensure they are placed away from flammable materials and never leave them unattended. Carbon monoxide detectors are crucial if using alternative heating sources like fireplaces or generators. Generators should always be operated outdoors in a well-ventilated area.
Authorities will be monitoring road conditions, particularly bridges and overpasses, for potential ice formation. While widespread icing might not be the primary concern with a dry freeze, pockets of moisture can still freeze, so exercise extreme caution if driving early tomorrow morning.

Frequently Asked Questions
- When exactly will temperatures drop below freezing?
Temperatures are expected to drop below freezing point (32°F) late this evening, likely around 9 PM – 11 PM, and remain there until mid-morning tomorrow, potentially as late as 10 AM. - Should I leave my water dripping all night?
Yes, it is highly recommended to leave at least one faucet dripping slowly in your home, especially those on exterior walls, to maintain water movement in your pipes and reduce the risk of freezing. - Is it safe to use a portable space heater overnight?
Space heaters can be safe when used correctly. Ensure they are on a flat, stable surface, at least three feet away from anything flammable, and plug directly into a wall outlet without extension cords. Never leave them unattended or use them while sleeping unless they have an automatic shut-off feature and are specifically rated for such use. - What should I do if my pipes freeze or burst?
First, locate and turn off your main water supply valve to prevent further damage. Then, contact a licensed plumber immediately. Do not attempt to thaw frozen pipes with an open flame. - How can I protect my outdoor sprinkler system?
If you have an irrigation system, ensure it is properly winterized. This usually involves shutting off the water supply to the system and draining the lines. Consult your system’s manual or a professional if unsure.
Staying informed and taking proactive steps tonight will significantly reduce the risks associated with this cold snap. Your preparedness not only protects your property but also contributes to the safety and well-being of our entire San Antonio community.
