@FOUND SOUL,
We have lots of big bush fires too, made worse by our high dry temps and to add, a dose of extreme difficult, high winds.
Tornados throughout my lifetime have been a sport. When younger, I was a storm chaser. But most storms were F1 an F2 with a few F3. Now we have been getting many more high F4 and F5 - killer Super Cells. Can't just get in bath tub with heavy covering. Must now be below the ground.
I don't have a shelter and it cost $4-5,000. I have a lot of $5-10,000 things I need that I will use a lot. Such as a boat. I may never need a shelter again in my lifetime. And truthfully, I never have needed one. How do you choose.
These Super Cells are beautiful - and to watch them, you are in an absolutely safe position - without "storm chasing". Just being close is enough. You actually have totally clear, blue skies above. Just be SSE and in front of the Super Cell, about 2-3 miles away.
