Thee will be a still be a ridge in the NE gulf which will not allow for such a sharp turn to the NE. I fully expect this to change more westerly with each new model run. The front is just not going to have any push left or be that strong by the time it reaches the southern states. Remember KATRINA last year. Looks how many time the major models had to shift left once she entered the gulf.


I think you misinterpreted my comment. I don't think there will be a shift west in the track, but east. Right now, the NHC has the 4 and 5 day points just a slow NW extension of the previous 3 days. Like WXMAN57 alluded to, they are going to have to make a decision about reacting to how the globals are handling the upper air environment. For about 4 or 5 successive runs the globals are forecast a sharp S-N weakness in the GOM. So, as soon as a turn is made, it will make a B-line north. Depending on its speed, there could be a late NNE or subtle NE turn toward the end.


Would that mean a slowdown in forward speed would allow that weakness to make it down quicker correct?

The GFS, NOGAPs, ETA, and GFDL all seem to be trending toward the N-NE apparently following the weakness in the 500 mb ridge - I know once they do that the panic button will be activated along some portion of the gulf coast - but they have committed themselves to making 120 hr forecasts so I'm hopeful they make a 100% best science decision on the track.


I can imagine that the folks at NHC have pulled most of their hair out already (thought hey don't have much to start with). Eventually, maybe this afternoon, certainly by tomorrow, they'll have to make a commitment to a landfall point. They just can't keep slowiing it down on days 4-5. If so, then many people may be quite surprised when it reaches them a day ahead of the earlier NHC forecasts.

I'd hate to be in their shoes with the 1-yr anniversary of Katrina coming up and a Cat 3+ heading for the same area, possibly.


LOL about the hair comment, I imagine they don't. :)

You make very good points. It was crazy last year when 2 days before Katrina, some mets still here telling us NOLA is safe.

I don't think they will take ANY chances this year even if it hits as far as TExas or Mexico.

This following does not express my own opinion and is strictly the opinion of JB from Accuweather...

JB thinks the models are overplaying the trough in the MS valley. He says he expects there to be a flat ridge holding north of the storm to push it NW through Thursday. By Friday he places this storm at 27.5N, 92.5W as a major hurricane.

Yup... i overstated "pounded with shear"... shear is there, but it didnt tear it up. So, if officially retrect my "put the wammy on him" statement.

Look out, here he comes. Still curious if a more NW movements occurs in the near term as he interacts with the retreating ULL however.

Well,law of averages says one of these storms had to get through the shear. Look out everybody... this one could be big.

And just in case anybody is interested, this is what it looks like when a storm is getting "pounded" by shear. Clearly this is not what Ernie looks like. ;)

The weakness is not a front that is moving from the US. The weakness is the fact that the western extent of the high is present.

If the models forecast the high to move westward across florida and then not build further into the GOM, the somewhere on the western extent of that high, the "weakness" resides. Keep in mid, there has been a general troughiness in the GOM for almost a week now, so a building high would have to replace all of that for there not to be a weakness.

JB is also trying desperately to verify his projected Texas landfall. Not that it can't come here, it sure could.

He has a valid point though. If the trough is not as amplified in the MS Valley, than the northward turn would likely be more gradual and further west right?

I agree totally what everybody is saying. Strong Cold fronts are not impossible but ususual for late August. Timing is everything. Just depends on where Ernie is located at the time the CF swings down and how far down in the gulf it digs down. Beaumont-Pensacola is still fair game. With Central LA-Mobile being the greatest risk in my opinion at this present time.

I sure hope Joe B is dead wrong for the sake of Houston and Galveston. Regardless of all the model runs and discussions I am making sure my propane tanks are filled today.

No. I just want to be sure that everybody understands the difference between a storm that is encountering weak to moderate shear and a storm that is getting the stuffing knocked out of it by shear. It just seems silly to me to suggest that Ernesto is, or is about to, fall apart because of the shear he is encountering. If you've seen "badly sheared" systems before, it's not difficult to tell that Ernie ain't even close to being "badly sheared."

It might be that you changed views from the Large view to the 1 km view the cloud tops do change colors, ie (more white in the larger view).

To me it looks like a normal, Caribbean-tracking, non-2005, tropical storm!!!

Very good Kat.Better be prepared than to be sorry later but hopefully it avoids your neck of the woods.

Skysummit you are correct. I have not been to any other sites, but you could PM me the details. My gut and that all it is right now is saying the weakness will form but not to the extent that will turn it like what happened to Ivan. Remember he was making a bee line straight for us and took that sharp right. This will probably do more like a Katrina and move more north, then a NNE turn at landfall NOT TRACK). Where it starts to make that north turn will be the million dollar question.

Local met says new guidance coming out shows Ernesto slowing down. How will that effect the track?

The slower it goes increases the chances of it having a more Eastern landfall.

I would think that slower storm = more intensification prior to entering GoM = tendency of storm to move more poleward = more northern component to track. However...it's too early to say.
