ATL: BARRY - Post-Tropical - Discussion

[Blinhart]

I'm wondering if there are some people that are questioning their decision to not open the Morganza spillway a month ago.

I've been questioning it since they decided that the flow wasn't strong enough. I'm sorry we have been having high river stages since February and don't expect it to drop to normal until the End of August, why not alleviate some of the pressure that has been up against the berms for months on end.

These rainfall amounts are frightening, are there estimates of what happens to NOLA if there's a foot of rain over such a wide area draining into the Mississippi?

Especially with the catastrophic disaster that would happen if the ORC failed or was overtopped due to a storm like this. This isnt new infrastructure either. Some of it is older than most people posting here.

When you can’t even point out the center of circulation that’s when you know how disorganized this storm is.

Watching The Weather Channel and one of the OCM’s mentions how much the wind has picked up and I’m thinking really!?

Convection is really starting to fire off

That swirly going around northern part of circulation of #Barry is not the center of the tropical storm and is heading southwestward to the west side. Landfall of the actual center should occur sometime early Saturday, but life-threatening inland floods continue long after that.

I would point out that the lone vortex is precisely what the NHC identified as the center on their latest advisory. I think it IS becoming the center. As it makes its small cyclonic loop the convection will begin to wrap around it tonight.

The red crosshairs mark the NHC's position:

Quickly becoming better organized. LLC approaching the main convection. I think 70 knots is a good bet.

Wouldn't this be overall better for New Orleans and Terrebonne Parish as far as rainfall? As it moves NW, that track would pull them out of the heaviest amounts.

No. All that squall activity will be moving across SE LA regardless. However, it's hard to say just where the bands of heaviest precip will develop tomorrow and Sunday.

Okay. I'm seeing something in the visible loop that I don't understand:

https://weather.cod.edu/satrad/?parms=s ... =undefined

Maybe some kind soul can explain it to me. Take a look at the left side of the circulation. If the real distinctive mesovortex that everybody's been discussing is the center of a clock, I'm talking about looking from roughly the center of the clock straight out toward 9:00. Actually, it isn't exactly radial: more like a bearing of 70°- 250°, and it holds that orientation. It looks like a searchlight (seen from the side) that moves up the feeder bands as they rotate toward the south. I think it's some sort of disturbance that's doing something to the individual patches of cumulus, but I'm just not sure. I've been looking at it for so long that I think I'm starting to see things.

First, does anybody see what I'm talking about?? It's visible in both the red and blue ABI bands. If so, well, any ideas as to what it might be?

Thanks...

We ready, live about 20 miles west of Lafayette so slightly west of the center cone

While it only gonna be a TD it has been a long time since we had a storm, Gustav was the last i think
So I'm expecting plenty of fallen utility poles and so on

Generator is fueled ready to go

Not to harp on a point, but we (NOLA) dont drain our rainwater to the Mississippi River. The river levees and the land nearest them constitute our highest elevations, and rainwater has always been drained away from the River and to the backswamp and Lake via canals and still is, now with pumps aiding gravity. Ironically, high rainfall amounts locally have much less effect on River levels than does high rainfall in the Upper Mississippi Valley. All that being said...looking at local news coverage right now and the River is pretty darned scary high.
