    Well Navy have now officially named this as 08, NHC will start at approx 15.45pm out time with there first update on track and intensity.

    Attached are the latest paths, GFDL doesn't make much of it. SHIPS initiates at 30Kt so this will be what the NHC go with in there first update.

    Strength will be really difficult with this one to judge, path pretty easy.

    I'll have you know that Humberto is my fine upstanding hairdresser and a jolly good job he does too.

    Anyway, thought you might be interestd in the previous Hurricane Humberto here:

    I don't like the projected track as it should stay away from the US. On the other hand, at least Mexico and the Carribean will get a respite after Dean and Felix.

    Still alot of unknowns

    THE AREA OF LOW PRESSURE EAST OF THE LESSER ANTILLES HAS ACQUIRED

    ENOUGH ORGANIZATION TO BE DECLARED A TROPICAL DEPRESSION...THE

    EIGHTH OF THE ATLANTIC SEASON. THE CENTER OF THE ELONGATED

    CIRCULATION APPEARS TO BE LOCATED JUST EAST OF THE THUNDERSTORM

    ACTIVITY DUE TO SOME EASTERLY SHEAR. DVORAK T NUMBERS FROM TAFB

    AND SAB SUPPORT 30 KT...WHICH WILL BE THE INITIAL INTENSITY.

    MICROWAVE AND VISIBLE SATELLITE IMAGERY SUGGESTS THAT THE CYCLONE

    HAS BEEN MOVING A LITTLE FASTER DURING THE PAST 6-12 HOURS AND THE

    INITIAL MOTION ESTIMATE IS A HIGHLY UNCERTAIN 295/10. THE

    DEPRESSION IS CURRENTLY LOCATED SOUTH OF A NARROW MID-LEVEL RIDGE

    AND THE TRACK GUIDANCE SUGGESTS A GENERAL WEST-NORTHWESTWARD HEADING

    DURING THE NEXT FEW DAYS. THE RIDGE IS FORECAST TO WEAKEN IN A DAY

    OR SO WHICH SHOULD CAUSE THE DEPRESSION TO DECELERATE AND MOVE

    SLOWER THAN CLIMATOLOGY.

    THE CURRENT EASTERLY SHEAR IS FORECAST TO WEAKEN DURING THE NEXT DAY

    OR SO WHICH SHOULD ALLOW FOR SOME STRENGTHENING. THUS...CONDITIONS

    APPEAR FAVORABLE FOR INTENSIFICATION DURING THE NEXT 2-3 DAYS.

    BEYOND 72 HOURS....AN UPPER LEVEL TROUGH LOCATED NORTH AND WEST OF

    THE CYCLONE IS EXPECTED TO INDUCE SOUTHWESTERLY SHEAR WHICH SHOULD

    HALT ANY ADDITIONAL STRENGTHENING.

    True... shame it's gonna be called Humberto!!! :o

    Ah, but there is a slim chance that it may be called Ingrid if TD9 reaches tropical storm strength first!

    The strength seems to be determined by the nature of the developing storm.

    Some storms seem to be able to cope with Shear, some completely collapse.

    There seems to be a very well defined LLCC with a good CDO, which probably hints that this might be one of the former categories and the NHC intensities are a bit conservative.

    FWIW this will probably be Ingrid rather then Humberto, TD9 will probably get there first as its so close to Texas and has deeper convection...

    Anyway yeah TD8 does look good right now with fairly deep convection over the center however there are still signs to me shear hasn't compeltely eased off and even more noteable signs that the air is still fairly dry to its north with WV showing quite a bit of dry air about. These two features may help to expain why the convection has eased just a tiny bit and has also been sheared off a little to the SW of the systems center. It should be noted that ther eis also currently what looks like the start of an inflow up from the south is trying to get going though it may just be an area of convection that is present in the ITCZ, hard to say without taking a better look at it.

    As for future strength, models generally suggest shear shouldn't be all that bad once it gets rid of this lot it presently has however that may not be a quick process. Despite that the system should slowly get better organised and once it gets past 50W should start to lose the shear and also. Dry air issue will need to be watched but more and more I think the heat content will help to pump. i don't think it will be a very fast former as its not really got a stunning set-up but develop it will and quite possibly into a strong hurricane.

    In terms of the track, next few days should be dominated by a WNW type motion, maybe not quite as much NW as the NHC suggests though as the models have had a pretty noteable right bias this year so far. Weakness in the Atlantic caused by a central Atlantic upper low (which is decaying) is allowing the system to move into a weakness and this is progged to grow tomorrow and to remain in place for the enxt 3-4 days. After that we see the wekaness really weaken and by that time the ridge will replace it and a motion back to 275-280 degrees looks much more likely. now where does that take this system. The NHC track would probably bend back westward eventually and aim towards the Bahamas in the long run. IMO this system will track a little further south and therefore could well be a threat to the Leeward Islands and the E.Major Antilles and after that assuming the ridge does develop back a more westward motion should occur...which will probably mean either a N.Caribbean threat or a SE USA threat...depending on the latitude it picks up in the next 3-4 days. Movement right now is very slow as it moves through very weak steerning currents caused by the weak weakness iin the ridge allowing slack motion to occur.

    This one wil lbe very interesting to watch and could be another powerful system, quite possibly even more eventual then Dean and Felix.

    This still looks quite decent. I think there is inflow(v.limited in the SW), generally good outflow. To the SW of the LLCC where the precip has been best winds of 40KT are being recorded.

    There is scope for this to be raised to a TS at 10pm.

    Shear is still taking a toll, but the system seems to be holding it's own.

    Ingrid it is.. well not yet but am i thinking it is a matter of time...

    Does this system have something of the Dean/Felix about it?

    Depending on the environment in front of it it may well attempt to 'outdo' them both!. After waking up to Humberto it would seem that some areas of the Carribean/G.O.M. are very capable of 'bombing' systems and I wonder just what central pressure the next 'cane will produce?

    Certainly a very sheared system, but I don't think shearing is really a reason not to upgrade a storm.

    This is certainly a 35Kt with quite a few 40Kt+ being reported now. Around a tight core, the core inself is covered by precip even though the North and East Quads are very sparse.

    TROPICAL STORM INGRID DISCUSSION NUMBER 7

    NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL082007

    1100 PM EDT THU SEP 13 2007

    A NOAA HURRICANE HUNTER PLANE HAS BEEN ON A RESEARCH MISSION THIS

    EVENING AND FOUND 35 KT WINDS USING THE ON-BOARD STEPPED-FREQUENCY

    MICROWAVE RADIOMETER (SFMR). THESE WINDS MATCH UP FAIRLY WELL TO A

    RECENT QUIKSCAT PASS THAT SUGGESTED WINDS OF ABOUT 35 KT AND

    SUBJECTIVE DVORAK SATELLITE ESTIMATES OF 35 KT. THE INITIAL

    INTENSITY IS RAISED TO 35 KT...MAKING THIS SYSTEM THE NINTH NAMED

    STORM OF THE YEAR.

    MODERATE WESTERLY VERTICAL WIND SHEAR CONTINUES TO AFFECT INGRID.

    MOST OF THE DYNAMICAL MODELS KEEP THE SHEAR ABOUT THE SAME FOR THE

    NEXT 24 HOURS...WHICH SHOULD ALLOW FOR A MODEST INCREASE IN

    STRENGTH. THEREAFTER...WESTERLY SHEAR SHOULD INTENSIFY...LIKELY

    CAUSING A WEAKENING OF INGRID. THE OFFICIAL FORECAST KEEPS THE

    SYSTEM A TROPICAL STORM FOR THE NEXT FEW DAYS...AND COULD BE A

    LITTLE TOO HIGH IN THE LONGER RANGE AS GLOBAL MODELS ARE SHOWING

    NEARLY 30 KT OF WESTERLY SHEAR IN THE STORM'S PATH.

    THE INITIAL MOTION HAS TURNED A LITTLE MORE TO THE RIGHT TONIGHT...

    ESTIMATED AT 300/5. THE TRACK FORECAST IS TRICKY AS IT PROBABLY

    HAS A STRONG DEPENDENCE ON THE FUTURE INTENSITY OF INGRID. WATER

    VAPOR IMAGES SHOW A MIDDLE- TO UPPER-LEVEL LOW DIGGING

    SOUTHWESTWARD TO THE NORTH OF THE SYSTEM. THIS LOW HAS CAUSED A

    VERY WEAK STEERING ENVIRONMENT WITH ONLY SLIGHT MIDDLE-LEVEL RIDGING

    REMAINING TO THE NORTHEAST OF THE TROPICAL CYCLONE. A STRONGER

    TROPICAL CYCLONE WOULD PROBABLY BE MORE RESPONSIVE TO THE

    LOW...AND MOVE FARTHER TO THE NORTH OF THE OFFICIAL FORECAST. IT

    IS ASSUMED THAT INGRID WILL REMAIN WEAK AND STAY ON THE SOUTHERN

    SIDE OF THE GUIDANCE ENVELOPE FOR NOW.

    Ingrid is barely hanging on to tropical storm status. Shear is really taking it's toll on Ingrid and it could disspate at anytime. Interestingly, shear is expected to relax in 48 hours, and if Ingrid lasts this long re-intensification could occur. An interesting possibility.

    TROPICAL STORM INGRID DISCUSSION NUMBER 12

    NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL082007

    500 AM EDT SAT SEP 15 2007

    IT HAS BEEN A CHALLENGE LOCATING THE LOW-LEVEL CIRCULATION OF INGRID

    EARLY THIS MORNING. BELLIGERENT SOUTHWESTERLY SHEAR IS TAKING A

    TOLL ON INGRID AND THE REMAINING DEEP CONVECTION IS CONFINED TO THE

    SOUTHEASTERN QUADRANT FROM THE ESTIMATED CENTER. DVORAK INTENSITY

    ESTIMATES FROM BOTH TAFB AND SAB REMAIN AT 35 KT AND SO WILL THE

    INITIAL INTENSITY. ANOTHER NOAA HURRICANE HUNTER AIRCRAFT WILL BE

    BACK INVESTIGATING THE CYCLONE AROUND 12Z...AND A MORE ACCURATE

    MEASUREMENT WILL BE TAKEN.

    INGRID IS EXPECTED TO REMAIN IN A STRONGLY SHEARED ENVIRONMENT AT

    LEAST FOR THE NEXT 48 HOURS. THESE UPPER-LEVEL WINDS SHOULD

    INHIBIT ANY STRENGTHENING AND COULD POSSIBLY CAUSE DISSIPATION OF

    THE CYCLONE. HOWEVER...AFTER 3 DAYS OR SO THE SHEAR IS FORECAST TO

    RELAX AND IF INGRID SURVIVES THAT LONG SOME OF THE INTENSITY

    GUIDANCE INDICATES THAT RESTRENGTHENING COULD OCCUR. THE OFFICIAL

    INTENSITY FORECAST IS SIMILAR TO THE PREVIOUS FORECAST AND

    MAINTAINS INGRID AS A MINIMAL TROPICAL CYCLONE THROUGH FIVE DAYS.

    THE INITIAL MOTION IS ESTIMATED AT 295/9. A GENERAL MOTION TO THE

    WEST-NORTHWEST TO NORTHWEST SHOULD CONTINUE FOR THE NEXT 24-48

    HOURS. THEREAFTER...A TURN MORE TOWARD THE NORTH-NORTHWEST WITH A

    SLIGHT DECREASE IN FORWARD MOTION IS ANTICIPATED AS INGRID...OR THE

    REMNANT LOW OF INGRID...RESPONDS TO A MID-LEVEL TROUGH TO ITS

    NORTH. THE MODEL GUIDANCE IS IN CLOSE AGREEMENT...BUT HAS SHIFTED A

    BIT MORE TO THE EAST THAN THE PREVIOUS CYCLE. THE OFFICIAL TRACK

    FORECAST FOLLOWS THIS REASONING AND IS JUST EAST OF THE PREVIOUS

    FORECAST.

    Ingrid certainly is a fighter, it reminds me of Irene in 2005 for it's tenacity. Shear is still over 20kts but Ingrid is looking better than it did this morning and the center is no longer exposed. It may even survive the next 48 hours of shear and restrengthen back to a tropical storm afterwards as the NHC discusses.

    TROPICAL DEPRESSION INGRID DISCUSSION NUMBER 17

    NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL082007

    1100 AM EDT SUN SEP 16 2007

    INGRID IS MAINTAINING ITS INTENSITY DESPITE THE HOSTILE UPPER-LEVEL

    FLOW. IN FACT...THE APPEARANCE OF THE SYSTEM IS LESS DISORGANIZED

    THAN IT WAS 24 HOURS AGO...WITH THE CENTER NO LONGER EXPOSED FROM

    THE DEEP CONVECTION. THE CURRENT INTENSITY ESTIMATE REMAINS AT 30

    KT IN AGREEMENT WITH A DVORAK ESTIMATE FROM TAFB. ACCORDING TO THE

    LATEST GFS RUN...VERTICAL SHEAR IS FORECAST TO REMAIN ABOVE 20 KT

    FOR THE NEXT 48 HOURS. THIS WOULD SEEM TO PRECLUDE ANY SIGNIFICANT

    RE-STRENGTHENING OVER THE NEXT DAY OR TWO. HOWEVER THE CONSENSUS OF

    SHIPS...THE GFDL...AND THE HWRF MODEL INDICATES THAT INGRID WILL

    EVENTUALLY REGAIN TROPICAL STORM STRENGTH...AS THE UPPER-LEVEL

    ENVIRONMENT IS FORECAST TO BECOME LESS HOSTILE LATE IN THE FORECAST

    PERIOD. FOR THE SAKE OF CONTINUITY WITH PREVIOUS FORECASTS THAT

    INDICATED DISSIPATION BY DAY 5...THE CURRENT NHC INTENSITY FORECAST

    MERELY MAINTAINS INGRID AT ITS CURRENT STRENGTH. HOWEVER THE NEXT

    NHC ADVISORY PACKAGE MAY NEED TO SHOW SOME RESTRENGTHENING.

    BASED ON GEOSTATIONARY AND MICROWAVE SATELLITE FIXES...THE INITIAL

    MOTION IS ONLY SLIGHTLY NORTH OF WEST...280/10. HOWEVER...THE

    MID-LEVEL RIDGE TO THE NORTH OF INGRID IS FORECAST TO WEAKEN. THIS

    SHOULD INDUCE A TURN TO THE RIGHT OVER THE NEXT SEVERAL DAYS...AS

    INDICATED BY THE MAJORITY OF THE TRACK GUIDANCE MODELS. IN 4-5

    DAYS A TROUGH DROPPING DOWN OVER THE WESTERN ATLANTIC IS EXPECTED

    TO TURN INGRID NORTHWARD. HOWEVER THE STEERING CURRENTS ARE NOT

    VERY WELL DEFINED SO A SLOW MOTION OF ONLY 4-5 KT IS INDICATED BY

    THE OFFICIAL TRACK FORECAST LATE IN THE PERIOD. THIS IS IN

    AGREEMENT WITH THE DYNAMICAL MODEL CONSENSUS.

    SINCE INGRID HAS MOVED SOMEWHAT MORE WESTWARD THAN EXPECTED...AND

    THERE IS LIMITED SKILL IN FORECASTING INTENSITY CHANGE...INTERESTS

    IN THE NORTHERN LEEWARD ISLANDS SHOULD MONITOR THE PROGRESS OF THIS

    SYSTEM.

    Sadly I've not got time to make a decent psot about Ingrid however it is a fighter of a system from the looks of the system, deep convection has restablished itself over Ingrid and while its been heavily sheared it still has strong convection, though in recent hours the LLC has become a little elongated and harder to find.

    There seems be be a little 'extension' to the south of the dissapating Ingrid that is developing and is not as 'sheared' as poor Ingrid......I wonder......
