The path is a general NW movement with wobbles WNW at times. The main issue on future path is land interaction with Haiti and Cuba, when it makes its west turn N or S of Cuba, then movement and strength and how much more intereaction with Cuba does this have to inpeede strengthening.I suggest we just watch this for the next 36-48hrs cause there is plenty of time to speculate where this will go after weds.

dry air is probally coming off of venesula land continent, cuss the se qaudrent is pulling air from it. All this should change soon.

EXTENDED FORECAST DISCUSSION
NWS HYDROMETEOROLOGICAL PREDICTION CENTER CAMP SPRINGS MD
319 PM EDT MON AUG 25 2008
TROPICAL STORM GUSTAV...
THINK THE NORTHEASTERN SYSTEM THE MODELS SPIN UP IN THE 60S
LONGITUDE WELL TO THE EAST-NORTHEAST OF GUSTAV WILL HAVE LITTLE
IMPACT ON GUSTAVS FUTURE TRACK OTHER THAN LEADING TO SLOW
MOTION...WHICH WAS SEEN WITHIN THE MEAN LAYER WINDS OF THE 00Z
ECMWF WHICH ADVERTISED WEST-NORTHWEST STEERING OF 5 KNOTS NEAR THE
NHC TRACK. THIS CONTINUES TO BE SHOWN THE 12Z GUIDANCE SUITE...AS
THE GUIDANCE NOW LIES WEST OF THE TRACK. DUE TO A LACK OF
SEPARATION BETWEEN GUSTAV AND THE SYSTEM IN THE ATLANTIC
SUBTROPICS EARLY IN THE PERIOD...CHOSE TO DEPICT THE SYSTEM
EAST-NORTHEAST OF GUSTAV AS A SURFACE TROUGH AFTER COORDINATION
WITH /TPC. GUSTAV IS EXPECTED TO TRACK NEAR THE FLORIDA KEYS
INTO THE GULF OF MEXICO EARLY NEXT WEEK...LURED INTO THE GULF OF
MEXICO BY A MID-LEVEL LOW EXPECTED TO FORM NEAR THE GULF COAST.

5:00 is out...forecast now right over Cuba, which should significant hinder development, at least in the short term.

The thin line moved a little west,but the cone is about the same.As we all know this will go back and forth over the coming days.The models are still all over the place on this one.

I think there needs to be set of consistent model runs with the flight data before we can speculate what will happen. No one knows how land interaction or missing Cuba will affect Gus.

I'm intrigued by to the NW, which will inhibit its movement in that direction - short term - and probably why it's forecast track is shifting west at this time. Gustav is still pretty compact and I'm not sure that previously noted eyewall is uniform through all layers. We've seen some of these tropical storms and minimal hurricanes get torn up by upper levels, and eventually the low-level circulation gets exposed and weakens. As rightly noted, there is great uncertainty in the long term at this point, and very interesting to note that /UK models seemingly weaken Gustav.

Latest vis pic shows new convection developing around the coc. Still, the outflow on the north and northeast is detached from the system. If Gustav runs the spine of Cuba, it will get rather disrupted by that terrain. I'll be watching this intently over the next few days.

Gustav looks considerably less organized to me than earlier this afternoon, likely due to the proximity to Hispanola. Once it clears the island (assuming it remains south of it), I imagine strengthening will proceed at a swift clip. In the meantime, hopefully it will be held in check.

I think its less proximity to land than the upper flow. The outflow at this point just isn't that impressive. Compare the outflow here to what Fay looked like over Florida. Gustav isn't having a problem firing off convection...its just not evacuating very well right now. That, however, is forecast to change in the next couple of days if it can get underneath an ULH . I found a picture of Fays outflow if you want a look.

WN Compare your pic with the current setup. Wave axis is the same SW to NE with cut off low. the outflow channel to the NE of Gustav looks the same only Gustav has much better overall structure and convection. Looks like eye feature is making a comeback also.

The eye looks to be making a comeback...I agree. My post about the outflow has to do with the length. G's seems to go and get dammed up at some point whereas F's goes almost to Iceland. That was the point I was making. G's structure is much better at this point than F's

Is anyone else seeing what appears to be a shift to due west for the motion over the last several hours?
Or maybe it's just an expansion to the west, hard to tell for sure...

WN agree with your assesment. Fays environment was somewhat different.Here is a time sensitive link to what will keep Gustav moving nw to wnw for a couple days- textbook .Fay did not have this constraint. Although depending on storm relative position these can have either a positive or negative effect on development. You can see the outflow to the NE of Gustav slamming into it. I'm thinking it is having a neutral effect on development right now but will keep Gustav on a more wnw track.

As many of you may have figured on, Gustav will be upgraded at the 5AM Advisory..... from the ...
REPORTS FROM AN AIR FORCE HURRICANE HUNTER AIRCRAFT INDICATE THAT
GUSTAV HAS BECOME A HURRICANE WITH MAXIMUM WINDS NEAR 80 MPH...130
KM/HR. THIS CHANGE WILL BE REFLECTED IN THE 5 AM EDT ADVISORY.
