Just an observation but seems TD19 wants to stay on the southern part of the cone for now at least.

The 7:00 am update is nearly outside of the original cone and, given the convective appearance this morning, it is likely that we see the center continue to try and consolidate to the SW. The current position is on extreme SW side of the 00z EPS spread but the 06z GEFS looks pretty good. Both of those show a track a bit SW of the current NHC track.

00z Euro EPS



06z GEFS

Not what I wanted to read first thing this morning, but thanks for the update.

Any intensity forecasts?

Well.... frick. Definately not liking the placement of that black line in the middle.

Not an ideal track for SELA. I just finished putting all my stuff back outside after the last threat.

Just noticed how slow this sucker is moving. That’s not good.

Zack Fradella saying right now he’s predicting landfall at the mouth of the river as a possible Cat 1 then moving over Nola, a bit westwardly of current NHC track because he expects the center of storm to follow the convection south for now as it enters the gulf

Impossible to say but the models show anything from a TS to a higher end Cat 2. However, rain will be the biggest issue with this system.

ETA: The 00z Euro and the 06z GFS both show over 20" of rain to the east of the track as the system slows down near landfall.

Damn that doesn’t give the center much land interaction. Not good, more time over water to intensify

Seems reasonable, esp. given the intense convection just south of the current NHC fix.



You can see on radar what appears to be the LLC rolling and contracting southwestward towards the apparent MLC associated with the very deep convection.



However, even with sat and radar things can not be what they appear to be.

That’s too many models coming into LC.

We didn’t get the surge for Laura. I guess God will be late bringing water to the party.

If this turns out to be a run event, we can’t take anymore here right now. Between the actual water and people’s mental health, it would be a shithow
