Are those heights measured above local terrain, or above some standard like MSL or something? Just wondering if a 28 foot levee is really that much higher than a 21 foot one somewhere else.
Above sea level I think.

No one expected the flooding today, til it happened.



That really complicates evacuation and sheltering . . . and this thing isn't even named yet.

The consensus TVCN hurricane model is basically the GFS from 12z. Its well east of the official track which may need to shift east.

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!

PTC2 is pretty naked this morning


Most convection is offset from the center in the broad cyclonic flow, westward quadrants.
I'm still thinking GFS is wrong & the ICON (with support of the euro) will reward my solidarity with it. I agree with the meandering further west before making the northward turn and sliding up LA towards the ArkLaTex.
I'm very curious to see how it plays out. Not just the track but also how well Possible Potential Tropical Something Barry Perhaps can develop.

... home grown mesoscale/nontropical derived systems are fascinating

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.

Carnival Valor diverted from returning home to New Orleans this morning and has instead docked in Mobile.

Barry is still forecast to reach hurricane strength before landfall, but NHC notes in their discussion that moderate northerly shear is now expected to persist until landfall. Hopefully that will help to keep the intensity in check.
