As a tornado destroyed Joplin, Missouri, yesterday, storm chaser Greg Johnson was in the area chasing other storms.

Johnson wasn't tracking that storm for his own safety, but went to the region on Monday and says he's never seen anything like it, "I was in Arkansas on April 27th for the super out break, the town that I was in was hit, it was devastated as well, but it's not even close to what I'm seeing here in Joplin"

The destruction so far is unheard of says Johnson, "from what we can tell this storm leveled in excess of two thousand structures."

"(The) preliminary rating is an EF4, which is wind speed in excess of 350 kilometers an hour." Making it one of the largest in history says Johnson

This tornado season is also shaping up to be the worst in history, having set single month (April) and single day (April 27) records for tornado activity.

As for his work down there, he's hoping this storm and what he's doing will act as a wake up call for Saskatchewan. "It happens where we are, we just don't have the awareness and we certainly don't have the warning system, we need to be better prepared where we are."
