One look at the damage told you the storm was a monster and now that's been confirmed.

The official rating for the twister is now as bad as it gets, EF5.

Survivors and other witnesses say the tornado looked to be a mile wide at times and was on the ground for 40 minutes while scraping a giant portion of Moore to the ground.

The official casualty count is changing as new information is released but as of this writing stands at 24 with that count almost certain to go higher as more areas are searched in the daylight.
