Important to Protect the Four Ps
Cold weather can pose a danger to the health and safety of Houston residents, and proper care should be taken to reduce your exposure to these conditions. When cold weather occurs, Houstonians should remember to protect People, Pets, Pipes, and Plants.
- Dress in warm clothing, wear gloves, coats and layers when you’re outside.
- Never leave children or the elderly in vehicles during cold weather, as they act as a refrigerator and can result in sub-freezing temperatures.
- Never use a generator, grill, camp-stove or any gasoline, propane, natural gas or charcoal-burning device to heat your home (or any enclosed area). This can generate carbon monoxide, which cannot be seen or smelled, but is deadly.
- Protect your pets by ensuring that they have a warm, safe place to sleep. The best place for a dog or cat is to sleep in a heated environment.
- Be sure not to shave your dog down to the skin in winter, as a longer coat will provide more warmth.
- Never leave your animal in a car during cold weather. Cars can cat as refrigerators in the interior, holding in the cold and causing animals to freeze to death.
- Protect pipes from freezing by leaving them on a small, slow drip during the freezing hours.
- Open lower cabinet doors to expose pipes to the warmth of the home.
- Protect plants from freezing by covering them with plant-cover fabric, or a light blanket with plastic sheeting on top of it.
Be sure to group plants that are in containers together, and near your home. Remember that soil in containers can get just as cold as the air temperature, and cause the roots to freeze, even if the above-surface leaves survive.
National Weather Service Information
- Thursday into the Christmas Holiday
- The Arctic front is on track to move into the area on Thursday. It will bring periods of freezing temperatures (and likely some <25°) into much of the weekend.
- Too early to confidently pinpoint exactly just how low readings will fall, or how many consecutive hours below freezing any single location will get.
- Confidence is high that we will see some bitterly cold air and freezing temperatures, but don’t focus on any individual model, or model run, this far out.
- The specifics will change as time progresses.
- All businesses and residents should begin preparation for some hard freezes before the coldest weather is set to move in on Thursday.
- For industry that needs an extended amount of lead time, the NWS encourages individuals to review plans/actions that might need to be implemented should conditions warrant (any extended durations of subfreezing temperatures, gale force winds, high seas, low water conditions, etc.)
