The fact the models are homing in on different areas suggests we will have more favourable conditions aloft but there is quite alot of uncertainty involved with how this one evolves.


Oh, gotcha! Yeah I'm not sure if we will get anything but GFS Para sure has been persistent so it opens my eyes a bit...

We're just getting out of Disaster mode here along the Texas Mexico Border. I'm concerned that another system would cause some more historic flooding.

But oh well it's up to mother nature.

LA GRULLA — Waters levels at Falcon Reservoir topped 308 feet early Thursday, marking a record high as runoff from Hurricane Alex and the tropical depression behind it continued to swell the Rio Grande, prompting more evacuations along border communities.
The record was broken at about 2 a.m., International Boundary and Water Commission spokeswoman Sally Spener said, and the lake still was rising.

The unprecedented volumes forced the binational IBWC to continue releasing water at 60,000 cubic feet, or about 450,000 gallons, per second.

“Hopefully there's not a hurricane,” said Robert Longoria, who was with the workers. “If there is, it's going to be the biggest disaster in history.”

CMC fairly agressive and probably a good deal too far north...yet again.

Its interesting to note, even with Conson in the WPAC, the models went too quickly to the north orginally and therefore we do have a big trend of some models underestimating the upper high.

That was the 00Z Canadian, KWT. It was definitely developing the wave way out by 40W in the very long range. However, the 12Z Canadian develops something coming out of the far SE Caribbean by Trinidad. I think you'd be hard-pressed to find any Canadian run that doesn't develop a storm somewhere this time of year. Usually it's wrong.

It ALL depends on the location and timing of the circulation of low pressure. There has been no such trend, your falling into an amateurish assumption so early in the season. Take 2005 for example, which had MH Emily and Dennis, the position of the low was instrumental in the path of both systems. People on the East Coast of the GOM as well as Central should be concerned as always especially with the MJO Pulse. There is typically always a moment of weakness in steering currents it becomes nothing more than a game of timing.

Of course there are exceptions, Hurricane Ike being my most famous. You tend to wanna believe weaknesses are more common but that storm taught alot of forecasters a big lesson.

12z Euro still weak but does see a highly amplified wave into the same region as the other models...obviously something that needs to be watched this time of year..

It's kind of funny how people are trying so hard to think that something is going to develop. I guess that's what happens when it's supposed to be an active season and here we are, July 16th, with barely anything out there. It's just a bunch of sheared convection, I don't see any kind of consolidation.

Whilst I know what your saying I'm pretty confident that nearly all of the storms thus far in the basin have been west of the forecast, not just in the Atlantic but in the other basins, the ECM has been closest thus far this year but thats because the ECM tends to have a better grip on upper high features then the other models.

Remember models do have biases, some modesl like the GFS/GFDL will be more prone to being right of the guidence whilst the ECM/UKMO more prone to the left side. Doesn't always work out like that though of course!

You may well be right though, I'm just talking about what I've observed in Alex, TD2 (though to a lesser extent), 95L was a little bit west of track (though I won't count that one!) TD2E, Blas, Darby and now Conson in the WPAC all tracked west of what the consensus of the models suggested. Of course that could well end tomorrow, who knows! :wink:

Anyway ECM not showing alot with this one as others have been saying, the GFS isn't nearly as keen till it gets in the BoC, could well be worth watching there though IMO

In case you missed the title of the board, it is called Talkin' Tropics which entails talking about possible development, which is exactly what this thread is doing. If you don't see anything or have a problem with those who are discussing the possibilities (regardless the chances) then there really is not a reason to post in this thread.

To be fair on what Ivanhater is saying, there is obviously a high level of anticipation this season with such a bullish expectation of tropical activity. So I think everyone is watching with greater enthusiasm than usual.

HPC mentioned that the MJO will be favorable for the next 7-10 days across the area in their Caribbean narrative this afternoon. Perhaps the switch is about to be turned on. :wink:

Yeah looks like we are going to see another attempt at an MJO , looks to be about the same strength as it was just pre-Alex system, but to he honest the MJO still isn't that strong really.

Still this one has a shot IMO if it can build itself enough distance from Mexico when it gets into the BoC.
