It gets pretty damn annoying when people think you should stifle discussion over a weather system on a weather forum. I always thought these threads of yours were umbrella topics to discuss anything tropical, even if it's banter over the 10-day GFS. I don't see how this is hurting anyone.

This is sort of why I don't post much on the weather side anymore. Hypersensitivity abounds, especially when it comes to the sacred TROPICS.

The 12Z Euro is, just as was the case 24 hours earlier, pretty tame with nothing but a very broad 1008 mb sfc low in the W. Caribbean at 198 hours. So, the GFS vs. Euro battle continues. Keep in mind, however, that it was the Euro that first had this as a 'cane in the western Atlantic.

This is actually kind of sad when you think about it. One has to wonder just how many others are out there that feel the same way. I don't think any of us that follow the tropics discourage reasonable discussions what so ever.

I think what we can take away from this run of the Euro is that there is a more solid Bermuda High... that's fairly intriguing... and that after the Hispaniola, the Euro looks to redevelop it in the Western Caribbean.

This is looking like a much different run versus previous Euros (24 hours ago pushed the remnants into Florida) and the GFS (Western Gulf scenario?) We'll see if it holds out...

Kind of silly.

First off, the discussions here are for the most part really cordial. Even today's "blowout" was a civil disagreement that resolved itself naturally with no namecalling. It was simply two viewpoints being expressed.

Secondly, if you're so averse to debate that it scares you off from wx discussion, either 1) you are too sensitive or 2) you're just not that interested in the subject matter in the first place. Anyone who really cares about the tropics is going to participate.

C'mon.

This is going to happen anytime LR model forecasts show a threat to the US. I'm not terribly surprised that little "blowout" happened earlier in the thread - I'm actually surprised it took this long into the season for it to happen. People want to see a hurricane and there are always going to be people that don't buy into it totally in the MR ( :whistle: ). That's obviously going to cause conflict. I actually didn't see anyone on either side overreact, but there were perceived overreactions that escalated things. It happens when people are emotionally invested in things.

Bingo. That's what I'm liking about it as well.

Where? Pouch P17L, you mean?

Agree entirely. If the object is to discuss (and hopefully for many of us) learn from the evolution of of storms during model runs, I can't see anything but good coming from talking about them ... even if the models are out in weather porn levels.

Perhaps some folks feel betrayed by the long-range models when they don't deliver the mega-storm they promised ... when it wasn't their's to promise in the first place?

Agreed, and with Ivanhater about the overall pattern. The pattern looks very interesting and seems to be quite indicative of a US threat IF anything develops, as others have discussed. This op EC run's issue with developing something is that it takes its developing low level vorticity center straight into Hispaniola, which disrupts it. But it is seemingly trying to reorganize it in the western Caribbean in the 192-216 hour timeframe.

It's getting close enough into the time frame that if I was at the WFO in SJU I would at least be getting intrigued given the model solutions.

1) It is similarly pretty benign looking for the U.S., such as was the case 24 hours ago, vs. the GFS' hurricane hits.

2) The 12Z GFS of yesterday wasn't western Gulf. It hit the S tip of FL and then went NW into the central Gulf coast (MS).

3) As you implied, the Euro has been pretty unstable. The GFS has been more consistent from run to run. This doesn't do too much for confidence in it vs. the GFS.

The Euro doesn't go out far enough to show evidence of whether or not the US is affected... hour 240 looks like it is headed towards the US, but it can't be confirmed for a few days.

I wasn't referring to the GFS having a western Gulf scenario, that was my guess for the upcoming hour plots for this Euro.

While the GFS has been more consistent, that doesn't mean that we can't discount the GFS' recent poor history against the Euro. Analyzing this run of the Euro versus previous runs, there have been some hints of similarities... such as a Hispaniolaish threat (with last night's 0Z run being the lone exception to both). At the moment, it appears we may start seeing the beginning of the "Euro west, GFS east" that has plagued the two models for most of the year... too early to tell for sure, but it's certainly interesting how this situation is unfolding.

Agree with your ideas. Just because the operational EC doesn't have a sub990 mb low plowing into the US like the GFS does doesn't mean it's not very interesting. If that vorticity maximum had missed Hispaniola it might very well have had an intense cyclone somewhere near the US in the 192-240 hour timeframe. That's why it's the pattern that is so intriguing to me. You combine that with the fact that we are approaching the more active part of the season climatologically and model signals of cyclogenesis in the basin - could be an interesting period coming up.

I mean as of hour 240. Whereas the 12Z gfs is already hitting SC with a H then, the 12Z Euro still just has a pretty weak and diffuse sfc low ((S GOM). It is, obviously, quite benign looking vs. the 12Z GFS at face value then.

Way too early to even say something like that. How many major Gulf hurricanes have approached the GOM looking "fairly benign"?

I'm just clarifying my original remark about the 12Z Euro looking relatively tame (still only a weak low in the S GOM) compared to the 12Z GFS's actual hurricane hit as of the end of the Euro run (240 hours). I'm not talking about what may occur later. You're reading way too much into my comment.

This, though, goes back to the entire Euro west/GFS east model issue. I'd lean toward the GFS being recurve-happy in this case.

We'll see. One reason I'm documenting these GFS runs is to see how well the model verifies after some very rare consistency (U.S. hit mainly within 8/26-8) covering ten runs in a row. Will it verify well? Will it totally blow it? These are some exciting times in the world of tropical wx forecasting!
