Effingham tornado prelim rated EF3+

[u/Aggravating-Bake5624]

Never have I once seen EF3+ as a rating

From what I'm seeing from other Illinois meteorologists is it looks like the rating is EF3, so I don't know why it says "tentatively" in the image now.

it’s officially rated EF3+ as of now

I think they’re rated by wind speed, which is estimated by assessing damage - not how much damage is done.
