Update on the tornado warning posts

After seeing how many views the tornado warnings netted, I have elected to post tornado warnings whenever tornado warnings happen.
This is to help people stay safe.
I will also post damage reports.
Because there are so many posts issued with the name tornado warning, I have put up a search box. Simple search your area and you may come up in a post issued by The Weather Centre.
Thanks for making us your severe weather headquarters.
