    Hurricane Ioke has now weakened to a category 2 hurricane from a category 4. What caused this sudden weakening?

    Don't know. The advisory said there would be little change in strength. The current advisory doesn't say anything either.

    Sorry to double post. Regardless of the weakening, GFDL seems to bring this system back up to Major hurricane status, which makes me think the weakening was due to an Eyewall replacement cycle. In fact, GDFL bring this system near or to Category 5 strength. 142kts at flight level and pressure at 927mbar, certianly looks to be Category 5 or very strong Category 4. Also, i expect this will become Typhoon Ioke if it continues on its present track.

    EDIT: You'll have to forward it to 20.

    Hurricane Ioke is ploughing its way through the C Pacific heading towards the 180W line! What's the record for the longest time a TC has had sustained winds of hurricane strength? Ioke seems never ending at the moment. Here's the latest from CPHC:

    Indeed Ioke is probably the strongest system to ever form in the central Pacific, it does look very impressive right now and by far the most impressive tropical cyclone this year so far, very impressive, tohugh it shouldn't get much stronger as its probably peaked pretty close to its lowest MPI and as the discussion noted ther eis just 1.1MS of shear over Ioke, thats amazingly low and is why Ioke has got such a perfect look to it right now, much akin to hurricane Rita last year actually.

    Amazing system this one is and very long lasting, I'm gonig to be very intreste dto see its eventual ACE (accumulated cyclone energy) will turn out to be, could well be very high indeed considering its heading into the favorable WPAC where it'll become super Typhoon Ioke.

    GFDL brings this storm down to 899mbar and maximum flight level winds of 162kts. If these winds were at surface level then they'd be rounded up to 190mph. Somehow this storm is going to seem a lot weaker after the windspeed is switched to 10 minute sustained. This storm is also growing larger. By the end of the GFDL run it's at least twice it's current size.

    Hi don’t usually post here only when big storms are on the go, I just thought id try and create a bit more interest for this thing, I mean it’s a fully fledged super typhoon it looks like a welt on the side of the earth, the fish out there most be getting the living **** beat out of them.

    post-6173-1156653175_thumb.jpg

    and there’s 5 times more posts on an Atlantic tropical storm, im defiantly sensing some Atlantic prejudice.

    Here’s some overnight development in case you missed it

    Hi Iain.

    Ioke will surely break quite a few records...how about longest time sustaining cat4/5 winds...not sure what the record is. This system is truly a beast and really the "perfect storm" - sorry to use the cliche but it really is!!! :lol: :p

    Just read this on Central Pacific Hurricane Centre website:

    IOKE WILL LIKELY GO THROUGH SEVERAL EYEWALL REPLACEMENT CYCLES OVER THE COMING DAYS...RESULTING IN SHORT TERM STRENGTH FLUCTUATIONS. HOWEVER...MODEL GUIDANCE KEEPS IOKE AT OR NEAR ITS CURRENT STRENGTH THROUGH 120 HOURS. NOGAPS AND UKMET ARE RATHER STEADY BUT...AS AN OUTLIER...GFDL WANTS TO STRENGTHEN IOKE TO 170 KT AT 96 HOURS. INCREASING SST AND LOW SHEAR ALONG THE FORECAST TRACK WILL...AT THE VERY LEAST...GREATLY SLOW IOKE/S DECAY AT HIGHER LATITUDES. THEREFORE...THE INTENSITY FORECAST IS UNCHANGED FROM THE PREVIOUS PACKAGE. IOKE COULD ENTER THE RECORD BOOKS FOR LONGEVITY AS A CATEGORY 4 OR GREATER STORM.

    This system is still holding its energy and is now predicted to hit Wake Island head on. Wake is a high-security US Military site, so don't expect too much information, but it is basically a small, low lying atoll with a large airport and several thousand personnel. With waves estimated at 48 feet and winds in the 130-170kmh range, severe damage is to be expected.

    Meanwhile, a new TC warning has been published for the East Pacific, off the Mexican Coast. If this develops, someone may want to start a new strand.

    Satellite images of Ioke are spectacular; I recommend a look at the JTWC multi-spectral images.

    Done some further checking on Wake Island.

    According to the update last week in the CIA worldbook, population at the moment is about 200 non-military personnel. Maximum elevation above sea level is 7 metres.

    ST Ioke has 46 foot waves associated with it. It's still heading for the Island, winds are still at the top end of the scale ; 135-165 kmh.

    I have not yet found comment on the situation, even in the American press. I hope the island will have been evacuated; there may not be much of it left in three days time.

    Wake Island certainly looks like it's in for a severe hammering...hope they got the people out of there!
