No, tornados are not common in Oregon. Very, very uncommon actually. The news guys said we rank 45th or lower in the list of states likely to get a tornado. Craziness!!
Fortunately, no serious injuries or deaths have been reported. The tornado touched down around 11:40 am this morning, destroying about a dozen homes and buildings. For the record, I believe Aumsville is a super small town (I've never actually been there), so I think it pretty much destroyed the town. I'm just glad everyone is okay!
