Flash floods occur a few times each year – the rain in the mountains drains very rapidly through the wadis towards the Dead Sea or the rift valley running between geological Israel & Jordan. It is a great experience if you are lucky enough to see one. A few words of caution – flash floods are extremely dangerous – almost every year some people get evacuated by helicopter or worse. If the road is closed then it is closed for a reason.
It is best to see the aftermath – like in our album here. After a flood you can often see some seasonal shrubs that flourish with the water and then hibernate until next winter.
