Yes, I did it on purpose to show that the words used make them easy to reverse.

I think one word should be stronger, or unambiguous.

Tornado sighting

Tornado alarm

Tornado touchdown

Tornado lookout

Tornado conditions

Tornado possibility

I go by Elk crossing warning signs a lot. They display all the time, giving their warning, not just when there's a recent sighting.

It's like saying the "red/black" rhyme about coral snakes is fine. It is, if you remember it exactly. And it's also incredibly easy to mix it up.

It’s clearly easy to get them reversed evidenced by the large number of people admitting it. I too had them reversed growing up, but took until I really got into learning weather in preparations for storm chasing way back before the internet. At least until I learned how expensive it is, and life had other plans for me.

Mocking someone for not understanding something you do is not a good look, and you should really try to be more empathetic. We all didn’t know something at one point.
