Yep a regular occurence when one lives in parts of Arabia, I lived in Saudi Arabia for a while, and you wanna see one of those coming, oh and it rains twice a year too, once for 2 days and the other for about 5 days!
Funnily enough Serena we received the exact photos from someone we know that is intending to go and live over there and we thought wow when we saw them too. I thought no way would I want to be caught in that.
