ATL: BARRY - Post-Tropical - Discussion

[typhoonty]

61 SFMR supports 60 so not sure why NHC stuck with 55.

The potential for shoaling as it's near the coastline. It's always possible to occur with lopsided systems like Barry, waiting for a more complete sample of the storm before increasing winds.

As bad as Barry looks on the northern half, the southern half looks mighty impressive. The story of this storm will be the flooding. It’s going to be unimaginable before this is over. Unfortunately, it will be a slow-motion nightmare over the next several days. If I lived south of I-10/I-12 in Louisiana, I’d be spending the weekend in San Antonio.

Elephant in the room...what if it does not turn north? Then what? Is this possible?

Like others have alluded to - Barry is not a deep system so it’s more influenced by low/mid-level steering. The ridge to the east is stronger at those levels than the one to the NW.

That's right.

I have friends doing just this!!! Hello San Antonio!!!

What is making landfall again? One of the most recent non impressive radar presentations I have seen in while. Rainfall will be an issue regardless

Not really possible at this point, Barry will turn Nw then north into weakness in ridge

[BRweather]

Barry center swirling around back to the east. I would expect a stair-step to the north for the larger gyre as the center swings back to the north.

NHC has 90.9W at 7PM. Looks like recon found it just to the east.

One of Barry's serious rain bands is already moving on shore into SE LA. That is the area of major concern, SE LA. IMO

First time seeing this in the NOLA Forecast Disco or any FD:

DECISION SUPPORT...

DSS code: Red.
Deployed: None.
Activation: None.
Activities: Tropical operations/Moderate to High Risk excessive rainfall/
Slight Risk severe weather/River flood warnings.

Decision Support Services (DSS) Code Legend
Green = No weather impacts that require action.
Blue = Long-fused watch, warning, or advisory in effect or high
visibility event; Marginal risk severe or excessive rain.
Yellow = Heightened impacts with short-fused watch, warning or
advisory issuances; radar support for slight risk severe
or excessive rain.
Orange = High Impacts; Enhanced risk severe; nearby tropical events;
HazMat or other large episodes.
Red = Full engagement for Moderate to high risk of severe and/or
excessive rainfall, or direct tropical threats; Events of
National Significance.

LITERALLY CODE RED.

I have family in Lafayette, Meux, Plaquemine, Jeanerette

Colder cloud tops on IR moving up the Mississippi Delta. Curious to see how quickly that stronger convection deepens as it too continues to wrap around.

[tarheelprogrammer]

Radar filling in a little bit better. You can start to see the beginnings of an inner core.

18z ECMWF apparantly delayed due to broken analysis...

I just pray that everyone in the high prone flood areas of NOLA and Southeast Loiusiana heeded the advice of authorities and got out of harm's way. I am extremely worried that the flooding we see down there in the next few days could be of catastrophic nature. This is a dire situation unfolding down there.

My continual prayers for everyone in the region!!

center being pulled towards the deep hot towers.. essentially stationary becasue that.. what that does for track if it sits here much longer.?/

Just heard the thunder. Looked outside to the east and saw a rainbow. Waiting on rain.

[ColdMiser123]

NOAA2 going for a W to E pass at ~27.9N. They will intersect the most intense convection at ~91W.

[Aric Dunn]

The leader cell is getting close and convection on the southern "eyewall" is starting to develop...

[Stormcenter]

Can someone please post the link to an infrared satellite loop of Barry? Thanks in advance.
