If you're in Texas (or elsewhere being impacted by this new polar vortex), hope you stay safe - and warm! I was still living in Texas when one hit, and it killed back our orange tree significantly, but we didn't lose power.
This one's worse - nearly 3 million without power reported in Texas alone - among them, my sister- and mother-in-law, who lives with my sister-in-law. They texted us this morning to report their power went out around 5 AM today, and it's currently showing 11' F outside their window.

Cold, cold, cold. She's been comforted by having a generator built into her house, but it never occurred to her to maintain it. She turned it on and it ran for about 2 minutes and then died, and it's covered with ice. So they are huddled around a gas fireplace and bundled up. Their only saving grace is that they do have natural gas, so they can cook on the stove top and take hot showers.
Brrr-r-r-r-r! We're very fortunate that it didn't travel to the Southeast USA.
