Major Hurricane Irene live tracking

Not to mention the fact that it is giant and loose right now, both detrimental factors when it comes to serious intensification.

A larger circulation is a good thing when it comes to land interaction, small storms/circulations are more vunerable to disruption & apt to change in shorter time periods, at least from what I know. If we have Irene (supposedly we do), and the large system can strengthen/consolidate a bit more, we may see it holds Its own at least a little better over land than it would if it were a small storm, just IMFO.

CUmet if this comes close to sfl as the gfs/ecm suggest care to guess on intensity? Perhaps minimal cane?

Taking the track verbatim (crossing both Hispaniola and Cuba), I would say somewhere between a strong TS to weak Cat 2.

Sure, but I was responding to cumet's post about the chances of a hurricane between now and Hispaniola.

I feel like every time a storm is hyped to be very strong, it turns out to be a dud.

Perhaps, but every scenario is different and in this case the synoptical regime steering the storm is somewhat different, and the shear between 200-300mb that screwed Emily does not seem to be present here. Maybe post a more detailed reasoning why this storm may turn out to be a dud (it might), rather than a one line snippet like this?

Just got outta work, looks like I'll have to concede to the use of Irene as the first significant threat of the season. :rolleyes:

Okay, with that out of the way, if a west trend develops, then this could be a significant hurricane south of Cuba, being August with warm waters, then a Charley-type track could be possible. Note I said track, not intensity.

The NHC track looks like complete crap if you want a red-meat hurricane out of this, but notice that if it shifts just a little to the left, we have a strong cyclone moving S of the Greater Antilles-- and suddenly a much more provocative scenario.

So, if the models trend left, this could get kind of interesting...

It's early in the process and there are at least two G-IV missions tasked. Looks like an interesting 6-7 days or so...

I don't think a Charley track is in the cards... there is no strong powerful upper level trough that is picking up Irene in the long range. The northward turn occurs because Irene is a vertically deep system and will feel a weakness in between two strong ridges. The storm will turn north, but it doesn't look like we are going to see a strong recurving solution, more of a slow northerly track beyond 96 hours as the ridge from the west attempts to build back in, slowing its progress northward further.

The NHC forecast shows pretty steady recovery after Cuba, with Day 5 being 55 kt. Extrapolating that trend suggests a good possibility of a Cat 1 impacting the Miami area.

Of course it's going to change, but that's interesting to note.

I think one of the major headlines with this storm will not be the wind, but the heavy rains along the east coast due to the slow movement. It'll be interesting to see the radar images over the islands.

With all of the Debbie downerisms aside for a moment, I think one question that needs to be asked more is why do the models strengthen Irene so much after Hispaniola and Cuba despite the disruption in circulation? We've seen plenty of instances of the models killing a storm near Hispaniola (Emily)...so it isn't a pattern.

I think it mainly has to do with the large size of the circulation as well as potential exceptionally favorable upper level conditions post-GAs. Also, keep in mind that with respect to Hispaniola, the angle of approach to the island seems to have a significant effect... With the position of the central peaks relative to the cyclone as a whole being key. The worst thing a TC could do is approach the island from the south or southeast heading directly for the central peaks. There is certainly no guarantee that is what happens with respect to Irene at the moment.

I think, overall, significant strengthening post-GAs as of now cannot be ruled out. Right now I'm leaning on the left side of model consensus based mainly on the trends of underforecasting the strength of the ridge... There is enough model evidence to support either the FL peninsula or GOM solutions, but I have to stick with GOM due to consistency of several ensembles.

Alas, if it comes to pass than Haiti becomes unlivable. Very very sad.

This may well be the bigger story for the future history of Irene and certainly is viable concern for the NHC and the support teams actively working that region. A million+ living in tents and ruins is not a good situation.

The good news is that the decent forward motion of Irene will help limit too much rain vs. a stalled or slow moving Jeanne like situation.

As modeled, it could be worse.
