A Word a Week Challenge: Unexpected

I was sitting in an airplane on the runway, waiting to take off, when I saw this unexpected sight out my window!

It’s called a “haboob”!

The definition I found to explain this strange phenomenon is this:  A haboob (Arabic: هَبوب‎ “blasting/drafting”) is a type of intense dust storm carried on an atmospheric gravity current. Haboobs occur regularly in arid regions 

It would appear that Phoenix AZ classifies as one of those arid regions!

And it was certainly something unexpected, that’s for sure!
