TWC is spending almost all of their time talking about Joaquin and not talking much about the ULL despite the fact the ULL will likely have a much bigger impact on the US. Also, they are talking about Joaquin and showing a map showing 12" or more of rain making it sound like Joaquin is going to bring over a foot of rain to the US. Very confusing.

Most people couldn't care less what causes their flood.

I agree with that but I am also reading a lot of comments on Facebook from people saying they won't get any rain because Joaquin is going out to sea. I think TWC is confusing a lot of people. The general public is associating the rain with Joaquin and assuming that if Joaquin goes out to sea then it won't rain.

They have a banner at the bottom of the screen saying "Flooding rains despite Joaquin"

Hard to argue against the major shifts in the models. With all the ingested data and strong trends east its clear the threat is at least lessening and significantly so for the east coast IMO. He does seem to be moving steadily westward right now so we will see if that has any implications down the road. 

 

Very complex setup and i'm sure its been rough on the forecasters.

Does anyone know what is influencing the eastward trend in the models? Is Joachim being influenced by the disturbance to the northeast or is there a change in the ULL?

 

Well way I see it is the timing is slower, when the models liked the landfall the storm was faster coming north out of the Bahamas and the ULL was further west so it was close enough to capture the storm but not close enough to kick it out and now the models are slower with the storm in the Bahamas and by the time the storm comes north the ULL is close and kicks to the storm OTS....

Just by looking at the GFS 06z vs 12z, comparing hour 90,  ULL hangs back a little longer in the newer run and isn't as far south and east when it needs to be...Joaquin is not as far north and slightly more east although not much...end result is not enough interaction so Joaquin is allowed to go OTS.

Check out the 12z from yesterday....a LOT faster (basically 24 hours quicker) and the interaction is there. Compare that with the runs today and the GFS is just now figuring out what the Euro has hand for a while.
