It's best if we use a little probabilistic reasoning -- "it's most likely to hit here" or "the probability of a hit here is small IMO". There's a ton of uncertainty at that range, but strong model consensus adds confidence that the western Gulf of Mexico coast as at the highest risk. Heck, there's a chance (probably greater than a FL hit, but less than a path through the Yucatan) that Dean will remain south that it never does emerge into the Gulf of Mexico after hitting Mexico, Honduras, and other Central America countries.

Of course, we've consistently seen storms that have been terribly forecast, storms that have ended up 1000s of miles from where all previous forecasts had them. Tropical cyclones (tracks and, in particular, intensities) are extremely difficult to forecast beyond 36 hrs, so it would be incredible to see any particular model solution verify perfectly at 4-5 days.



Wow, that would be something if it didn't even enter the gulf and just went into Mexico/ Central America instead. Like you said, that's a possibility, but someone will still have to deal with the horrible effects from it regardless.

HDOBs are coming in garbled into the NHC's FTP servers. With no valid data there, they are not going out to other sites.

ftp://ftp.nhc.noaa.gov/pub/products/nhc/recon/

Anyone have any idea what to make of this file:
http://twister.sbs.ohio-state.edu/text/ ... XXX50.KWAL

The NHC recon server has that data in it. It look very much garbled, but can anyone make sense of part of it?

That's just common sense.
I agree. I think Mexico, Texas and Lousiana are the most likely candidates ATM..and that is due to how the upper level environment seems to be setting up ahead of this system. Areas east of Lousiana are not out of the woods yet by any means though, but with each passing day the chances look less and less likely that the storm will hit there. Lot's to watch in the coming days, and things could potentially change. We should be able to pinpoint the forecast path much better by Saturday or Sunday.

So if the current forecast pans out, I guess it will make history to be a hurricane that has tracked that far west from where it originated. And didn't read on Jeff's blog a couple of weeks back that the west gulf coast was the target this year instead of the east coast? I sure hate to see texas get this or la because too soon still after katrina for la and texas needs a major break from all that rain. Lo siento mi hermanos de mexico pero yo creo pueden tener la tormenta dean. And that is my poor attempt at spanish.

I believe they are north of the projected path - but most likely are or should be in a warning area.

Thinking the high will retreat by the time Dean is in the central Gulf sending him on a more northern course towards us. He said Dean is something we are going to have to watch carefully.


Same here, local met at 5 said the models were showing possibly a more northward turn in the Gulf and that it needed to be closely monitored, especially in TX and LA.

Unfortunately, that was the feeling of a lot of the older folks in my neighborhood for Katrina, and it didn't turn out so well. I'm glad my parents had moved away before Katrina because my dad was also the type that would never leave, and the house that they lived in was one story, outside the levee protection, and it collapsed. Hopefully, Dean won't head your way, and you can convince them to evacuate if it does.

what's the likelihood of the Yucatan peninsula being Dean's graveyard?? It's happened before!

GFS has been consistent. Lets see what happens with the 0Z model runs after the Gulf stream data gets completely utilized

looks like Dean may have levelled off in intensity for a little while now...the partial eye seen earlier now longer clear cut @ all...from latest IR it would suggest the center may also be south of 14N once again

Hi, this is Antonio, from Tampico Mexico at Gulf of Mexico, were are watching Dean track and its forecast , Dean remembers me Hurricane Gilbert 1988 path, being a thread to Jamaica, Cancun, and then Mexico - USA border states, also Gilbert reached its Cat 5 at western caribean sea, let´s see if Dean continues to be similar as Gilbert.

Greetings,

Fortunately, my parent's house is not in a flood zone. Fortunately, they are VERY close to a major hospital. Fortunately, there are several families on the street that have been there as long as my parents (40+ years), so they all know each other.

It's the aftermath that worries me most - we can hold out through the storm. But weeks of no power, no supplies, endless heat? no.. that would not be a liveable situation.

Still should be the NOAA jet. (around the storm up high) I know there is not an AF mission scheduled, but I thought they might add another plane in sooner for the first islands to be affected since tomorrow will be too late.

I highly doubt Dean would be able to come in any stronger than a 3 with all the dry air it'd be pulling in hitting Texas
