Wow, that looks terrifying!
(If it is indeed true what they are predicting.) Sadly, I think this kind of storm is going to be the norm from now on. I was saying to DH this week, when we were children/ teens/young adults, in the late 1970s, 1980s, and early 1990s, we never saw anything like this, or the horrific flooding we have been experiencing. (Well, very rarely anyway.)
Seems like a 21st century thing. Floods happen every year now. Would have been a once a decade thing some years ago - if that. Scary.
