Winter Storm Safety Guide

Severe winter storms in Texas aren’t as common as in other states, which can make them all the more dangerous if you’re unprepared for ice and snow. In February 2021, winter storm Uri led to power outages across the state, leaving millions of Texans without electricity during freezing conditions.

Winter storms can include blizzards, ice, freezing rain, snow, and sustained freezing temperatures. Texas officials have warned of possible extreme weather conditions this winter but claim the power grid is better prepared than last year. The Electric Reliability Council of Texas (ERCOT) has added over 10,000 megawatts of new power since the summer of 2023, including solar, wind, and natural gas. ERCOT has also improved weatherproofing since winter storm Uri in 2021. Despite these upgrades, rising power demand and inefficient heating systems could still strain the grid.

According to the National Weather Service, most of the danger from winter storms are not related to the storm itself. Any of these weather conditions can lead to dangers on the road and in your home. Read on for winter storm safety tips to prepare, stay safe, and protect your home during a winter storm in Texas.

Winter storm watch vs. winter storm warning

A winter storm watch or warning works similarly to a tornado warning, alerting you about changing weather conditions and the need for preparation. Understanding the difference can help you take the right steps to stay safe and manage your energy use during severe winter weather in Texas.

• Winter storm advisory: Be aware of winter conditions, such as snow or freezing rain. You should exercise caution while driving or being outdoors.
• Winter storm watch: Winter conditions are possible within 12 and 48 hours. Now is the time to review your storm plan and stay updated on the local forecast.
• Winter storm warning: Severe winter conditions, such as heavy snow or sleet, have begun or will begin within 24 hours. You should take action when a warning is issued.

Winter storm preparedness

There are several ways you can prepare for a winter storm ahead of time. Start by making a plan of action with your household members. This can save time and keep you safe in the event of a weather emergency.

• Weatherproof your home: Insulate water lines along exterior walls to prevent freezing and potential pipe bursts. Weather-strip your doors and windows to keep the cold out and improve energy efficiency. Repair any leaks in your roof or windows to avoid water damage during a storm.
• Prepare your vehicle: Make sure your vehicle is prepared for winter weather in case you need to drive. Check the tire air pressure, keep the gas tank near full, and ensure all essential vehicle systems like the heater, brakes, and battery are in good working condition.
• Take care of pets and livestock: Move animals to sheltered areas, and ensure abundant water and food supply.
• Consider outdoor furniture: Prepare any outdoor furniture for the weather. You may need to cover or strap down patio furniture before snow, ice, or hail arrives.

Pack an emergency supplies kit

Emergency kits are helpful during winter storms but are also important in the event of a hurricane, tornado, or other type of weather event.

The following is a list of emergency supplies to have in your home for winter storms or any weather emergency:

• Water — one gallon per person per day, with at least a three-day supply
• Food— a three-day supply of nonperishables that don’t require refrigeration or electricity
• Flashlights and extra batteries
• A battery-powered radio and extra batteries
• Portable cell phone charger
• A first-aid kit
• A seven-day supply of medications and any other necessary medical items you may need.
• Copies of keys and personal documents
• Any necessary supplies for your pets

Power outage readiness and heating safety

Contact your utility company to report a power outage and find out when service will be restored. You can use our power outage guide for detailed information about how to stay safe and protect your home during an electrical outage. Here are a few additional safety tips to know during a winter storm or power outage:

• Do not use a grill or oven for warmth. Keep generators in a well-ventilated area and do not bring them inside your home. These items are a fire risk and can cause carbon monoxide poisoning.
• Cold air escapes when you open your refrigerator and freezer. Keeping them closed will keep your food at a safe temperature longer.
• Unplug devices and appliances like your TV, computers, and other large appliances to protect from a power surge when electricity is restored.
• Turn your faucets on slightly so they’re dripping during cold weather. This will prevent your pipes from freezing and bursting during winter storms by keeping the water running.
• Consider using battery-powered flashlights or lanterns instead of candles to prevent potential fires. If you do use candles, don’t leave them unattended.
• Conserve heat in your home by keeping doors and windows closed and sealing any cracks.

What to do after a winter storm

Continue monitoring local news broadcasts for updates about road conditions, closures, water safety, and power outages in your area. Avoid driving if there’s still snow and ice as it can linger on small and shaded roads for several days after the storm.

Ice can also weigh down power lines and cause them to fall, blocking roadways and causing dangerous driving conditions. If you need to drive, make sure your exhaust pipe is clear and you brush all of the snow off your roof and windshield to avoid added dangers on the road.

Check in with neighbors, friends, and family who may have been impacted by the winter storm, especially those who are elderly or disabled as they may have trouble navigating the icy conditions. Maintaining communication with those around you ensures everyone is accounted for and receives the support they need.
