Hoping all the people in Texas are staying safe right now through that snow storm.
Few tips for people with no power, layer up with material (like cotton) sweaters then put a windbreaker or a jacket over it when inside. Run your tap just a little so your pipes don't bust. When going to bed if you don't live alone tuck towels under door to insulate the room-
-and have your family stay in ONE ROOM, body heat goes a long way and should help with keeping you warm. (If alone still try to insulate the room.)
I've also been hearing around that people are using their gas ovens and leaving them open to heat up the house, DO. NOT. do this it is NOT safe and you may not wake up. Safer option is to boil some water while you are AWAKE.
Feel free to add some more things and keep our Texan friends in our thoughts because unfortunately we have and are losing people to not being informed and desperately trying to get warm.
