I know this might be overreacting, and I have not said a peep about it to my kids or anyone else...
Last week, my kids wanted to call my mom during the day. On her last visit, they had talked about calling her on her day off at home. She was in the shower, so they got the answering machine. I sent her a text, asking her to call if she had time.
They each talked to her for about 5 minutes, and I was busy doing laundry. Afterward, my daughter said, "You know what? Grandma told me there were FIFTY tornadoes in Tennessee yesterday!" She had apparently also asked about the weather here, "Is it raining there?" I know that in Michigan, we all love talking about the weather, so maybe it was just an interesting and "safe" topic for her to express.
I didn't comment on this, but just thought to myself that she was planting some "end time" seeds in their young minds. My kids are 6 and 7. I'm not going to react, but will be noticing if she says anything else that sounds fishy. My daughter used to be very scared of thunderstorms and wind... why would she bring this up? Last summer, my daughter asked me daily if there was going to be a tornado. (They might have been too young to watch The Wizard of Oz, after all... haha)
