Street flooding is fairly common in New Orleans. We lived there from 1981-1985. The very first morning after we moved in, there was heavy rain and the street completely filled up with water. I'm sure the neighbors were laughing at our newbie-ness as we stood out in front of the house gawking!No one expected the flooding today, til it happened.
That really complicates evacuation and sheltering . . . and this thing isn't even named yet.
While the looming catastrophic flooding is sobering, as a layperson I've got to say this is the first time I've ever watched the formation of a tropical system from the inside, so to speak (the Hurricane Hunter reports and other NHC information on the website, posts here, NWS online) and it's fascinating, too. Horrible, in this instance, but awesome to watch an Earth system do its thing. If only people didn't have to suffer from it.... home grown mesoscale/nontropical derived systems are fascinating
