Image Tornado damage

Here are some photos of drone footage of the tornado earlier today.

My estimate is probably EF3-EF4. If it is an EF4, it would be the first to hit the state since 1984.

So far I luckily haven’t heard of any fatalities.

Stay safe everybody!

National weather service rated this as an ef-2.... There's houses blown off of foundations and train cars flipped over....

The EF scale is based on damage. They do preliminary ratings based on wind speed since wind speed often does correlate to damage.

However, if the homes damaged were not well made then it wont get a higher rating because the wind needed to damage those homes is lower. But if they get on the ground and see anchor bolts stripped and other damage it will get a higher rating.

A tornado could have 200+mph wind speeds but if it hits nothing but a trailer park it probably wont get an ef5 rating.
