That area is within the 5 day cone by the NHC.

yeah, it's an outlier...meaning that NE Mexico/Texas is less likely a target...SW Louisiana is even less likely if even possible with such a strong ridge and a ULL moving out of the way and showing no signs of stalling as some are wishfully suggesting.

Nobody is wishfully suggesting a stall, we're simply stating that it's slowed down. There's a difference.

What will this mean for Texas?


Dean will be slingshoted toward Texas in my opinion.


Please, stop making statements without a shred of supporting evidence...you earlier stated in the thread that you wanted a hurricane to hit Texas. With that statement and your continuous claims of a Texas landfall when all of the pro-mets are suggesting otherwise really takes away any credibility and objectivity you have...no offense, but there are others in this thread who actually might take your posts seriously...which are mostly disinformation and overhyping. :roll:

Most of the pro-mets here seem to think that the ULL is not a concern and that Texas is in good shape...I really don't see the need to be this concerned this far out, seriously.

Here is what MWatkins had to say followed by Derek Ortt's thoughts:

Quick Sunday evening update...

Dean is passing just south of Jamacia tonight, but they are on the strong side of the storm. So while they are fortunate that the eye is not passing directly over them, there will surely be reports of significant damage when Dean has cleared out tomorrow.

From there, as has been well documented by the NHC and others in this forum...the guidance has shifted significantly southward since Friday...and the upper low in the Gulf appears to be clearing the pattern quicky. There are now no models that take Dean into Texas...let alone the central Gulf as the GFDL was doing last week.

This should drive Dean into Mexico...where it may or may not emerge briefly in the Bay of Campechee before making a second Mexican landfall mid-week.

Although Texas is not "in the clear", it is hard to imagine Dean getting very far north in this steering environment. It is about as straight forward as a track forecast can be at this point.

Mexico Only: 95%
Mexico, US Landfall: 5%

MW

The eyewall scraped the south coast of Jamaica this afternoon as Dean moved to the WNW. 500mb winds and WV imagery show that the slightly north of due west track should continue for the next few days, taking Dean south of Cayman, into the Yucatan and into the Bay of Campeche. The upper low continues to retrograde to the west and should not impart an influence on the steering. This track is adjusted somewhat south of the previous and unfortunately brings the eye inland into the more populated parts of mainland Mexico.

Dean may have weakened slightly due to the interaction with Jamaica; however, conditions are very favorable for intensification into a category 5 hurricane when it moves into the open NW Caribbean and this forecast continues to indicate a landfalling category 5 hurricane on the Yucatan. Significant weakening will occur over the Yucatan; however, re-intensification is likely once back over the water. The landfall forecast is 100KT, but cannot be reflected in the table since landfall occurs between forecast points.

Newest discussion - they don't even MENTION the ULL. Interesting.

WTNT44 KNHC 200300
TCDAT4
HURRICANE DEAN DISCUSSION NUMBER 28
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL042007
1100 PM EDT SUN AUG 19 2007

THE EYE OF DEAN HAS BEEN PASSING JUST SOUTH OF JAMAICA SINCE ABOUT
1900 UTC AND HAS JUST CROSSED THE LONGITUDE OF NEGRIL ON THE
WESTERN END OF THE ISLAND. THE CENTER CAME WITHIN ABOUT 20 N MI OF
PORTLAND POINT ON THE SOUTH-CENTRAL COAST...CLOSE ENOUGH TO BRING
HURRICANE-FORCE WINDS TO KINGSTON. WHILE PASSING BY JAMAICA...
SATELLITE IMAGERY SUGGESTED THE EYE DIAMETER WAS GRADUALLY
SHRINKING. AN AIR FORCE HURRICANE HUNTER AIRCRAFT ARRIVED IN THE
EYE OF DEAN AT 0130 UTC AND REVEALED THAT THE PRESSURE HAD FALLEN
TO NEAR 925 MB...AND THAT DEAN NOW HAS A SINGLE EYEWALL AT A
DIAMETER OF ABOUT 15 N MI. MAXIMUM SURFACE WINDS FROM THE SFMR
HAVE BEEN 121 KT...AND FLIGHT-LEVEL WINDS HAVE BEEN AS HIGH AS 143
KT...BOTH OF WHICH SUPPORT MAINTAINING THE ADVISORY INTENSITY AT
125 KT.

DEAN IS HEADING TOWARD 280 DEGREES AT ABOUT 17 KT WITH STEERING
PROVIDED BY A STRENGTHENING MID-LEVEL RIDGE OVER THE SOUTHEASTERN
UNITED STATES. THE MODELS ALL AGREE THAT THE RIDGE WILL GET EVEN
STRONGER AND MOVE A LITTLE WESTWARD WITH DEAN...MEANING THAT DEAN
WILL PROBABLY MOVE IN A RATHER STRAIGHT LINE UNTIL FINAL LANDFALL
IN MEXICO. OVERALL THE MODELS HAVE AGAIN EDGED A LITTLE
SOUTHWARD...AND SO HAS THE OFFICIAL FORECAST. THE NOAA
GULFSTREAM-IV JET CONDUCTED A SYNOPTIC SURVEILLANCE MISSION THIS
EVENING TO PROVIDE DATA FOR THE 0000 UTC MODEL CYCLE. THE JET WILL
CONTINUE TO FLY MISSIONS EVERY 12 HOURS TO COLLECT DATA THROUGH THE
12Z MODEL CYCLE TUESDAY MORNING.

ALL OF THE OBJECTIVE GUIDANCE CALLS FOR STRENGTHENING IN THE
NORTHWESTERN CARIBBEAN WHERE THE SHEAR WILL REMAIN WEAK AND THE
OCEAN HEAT CONTENT VERY HIGH. THE OFFICIAL FORECAST FOLLOWS SUIT
AND INDICATES THAT DEAN COULD REACH CATEGORY FIVE STATUS DURING THE
NEXT DAY OR SO. THE HURRICANE WILL WEAKEN WHILE OVER YUCATAN IN
PROPORTION TO JUST HOW LONG IT SPENDS OVER LAND. THE OPPORTUNITY
FOR RESTRENGTHENING OVER THE SOUTHWESTERN GULF LIKEWISE DEPENDS ON
THE EXACT TRACK...AND THAT WINDOW HAS BEEN SHORTENING WITH THE
SOUTHWARD SHIFTS IN TRACK. ALTHOUGH NOT EXPLICITLY INDICATED IN
THE NEW OFFICIAL FORECAST...IT IS STILL POSSIBLE THAT DEAN COULD
RESTRENGTHEN AND AGAIN REACH MAJOR HURRICANE STATUS PRIOR TO FINAL
LANDFALL ALONG THE COAST OF MAINLAND MEXICO.



FORECAST POSITIONS AND MAX WINDS

INITIAL 20/0300Z 17.6N 78.8W 125 KT

And Dean reacts to that slow down by veering left of track.

I'm not buying that phantom ULL. Dean has been underneath all those influences so far and shown us so.

yes it does, in fact on the last 2 frames, it appears that it is heading EAST, and not west. Guys, should this not move much by morning, then we may wake up to a whole different ball game folks.

IMO this talk of the ULL slowing down or what not is poop. The ridge is still strengthening and nudging west, the ULL will have no affect on Dean. Sorry people I disagree with :)

Not being anything but a hurricane enthusiast, I think this will be the first time that we haven't had a surprise in the track in the last 4 years I have been seriously watching GULF hurricanes. Not once that I can remember have they pegged it straight from beginning to end. But, don't quote me. Just thinking.

HEY, I am NOT -removed-, nor would i EVER, EVER, EVER wish a cane on anyone, much less a strong cane. We are just noting what the model sees, and discuss it, It may not turn north, but it is still a possiblity, abit VERY slim.

If that new track verifies, that would mean a break for the Cayman Islands and Cancun....But then isn't Cantore in Cancun? Of course Cancun is safe.

Not -removed- here. Just looking at various sources of info - models, satellite, IR, etc. - and discussing it. Add in Dr. Neil Frank mentioning it in his newscast and it's kind of interesting to talk about.

The models do change from time to time. Not expecting a major change, but things do change with each run.

I do not see this as -removed-....this is a MB that is dedicated to have people discuss the weather...they are posting for discussion sake....I think that the term -removed- is overused!!

Don't take offense to it... if Dean ends up anywhere north of the current projections it will be obvious that someone else was doing the -removed- (not going to point fingers here) and if it remains on the NHC track through landfall I will just claim that I was doing reverse psychology -removed- :) Stay away Dean... poop though? really...

The forecast has been quite consistant, I agree. I think it has been because we have had a very dominant area of high pressure, which usually means more often than not, a westward motion. Not even the intensity of Dean has been a surprise. Remember that the last time the Caribbean saw a major hurricane was Hurricane Beta in 2005, and it affected mainly the southern Caribbean.

That pretty much goes against everything people are saying on this board.

That's what I've been thinking.

It's like the old joke...

"Where's the safest place to be in a hurricane?"

"At the center of the 5-day cone."

Ba da bump.

Seriously, though, it's truly odd to a) have a major hurricane more or less make a 3000 mile beeline with very little change in direction and b) to have such strong agreement in the models so far out.

I know in watching hurricanes for 20 years I've very rarely recalled the 5-day and thought to myself, "Well played, NHC." (By the way, this is in no way slamming the NHC - they do a fantastic job with some of the most advanced weather tools in the world. It's saying that this is damn hard to do and when you're right to within 300 miles 5 days out and that's considered acceptable that this is a tough job.) But the fact is that 5 days are usually prone to outlier events beyond the scope of most current models...

Something has to give, right?

don't worry mate, I didn't take offense, just my Fired up temper shall we say.


anyway let's wait till the rest of the models come out to see if we even should worry again for a US landfall.

Don't forget Jim Cantore was in Gulfport, MS at the Armed Foreces Retirement Home riding out Katrina on the third floor because the water rose so high.

We fear Jom Cantore.
