    Hi. Yeah, this probably sounds wrong and tactless, but it's during these storms/systems, that brings it all back from last years Hurricane threads - they were good viewing:D

    I guess these cyclones only help us to will on the hurricane season our end :D

    Well I'll keep this breif but Wati is entering a fairly favorable area for strengthening. It's presently got a central pressure of 975mbs and is a cat-2 on the Cyclone Category System. Looking at its track looks like the steering currents are going to send this system very close to where Larry just hit, probably as a cat-3/4 I reckon.

    Updates on Wati from BOM. Very interesting, looks like no-one knows what will happen next. It's now moving West-Northwest! Was expected to start turning South, is this just a small move before the turn or a I won't follow your rules move that flies in the face of the predictions? Time will tell I guess.

    At 10pm EST Tuesday, Tropical Cyclone Wati, category 2 with central pressure 975

    hPa, over the central Coral Sea.

    Wati is positioned at 10pm near 17.5S 154.1E, which is about 660km northeast of

    Mackay. Tropical Cyclone Wati is moving towards the west-northwest at 13 km per

    hour and should gradually intensify over the next 24 hours.

    Wati has slowed a little in the last few hours and in is expected to remain slow

    moving in offshore waters for the rest of the week. The combination of this

    system and a 1028 hPa high in the Tasman Sea is expected to produce strong to

    gale force winds off the coast between Bowen and Fraser Island. Large seas will

    develop along open waters of the southern and central coasts.

    In the longer term the forecast track of Wati will be complicated by the

    approach of an upper level system from the west. Depending on the strength of

    this upper system Wati will either; be captured and move SE parallel to the

    Queensland coast or remain slow moving until the upper system weakens and then

    move slowly towards the Queensland coast over the later part of the weekend. The

    upper level system and Wati will be closely monitored over the next few days

    when the eventual track will be clearer.

    The next bulletin will be issued at 5am Wednesday.

    This shows the slight jump North. Can't seem to show picture but here is the link.

    It may well be that its just wobbling alot, not quite sure why, it may well due to a slight strengthening of the 1028mbs HP cel lto its south-west and therefore may have forced it to take a WNW track for a little while till the HP cell shrinks back a little and allows it to go back onto a more westerly/WSW track again.

    To be honest I'm really only guessing as I've got no acess to any real sort of data from the area but when storms wobble in the atlantic its usually because they are feeling the effects of a ridge gettin stronger or weaker but when storms do this, they are so hard to forecasts even for the pros.

    It does seem to be getting increasingly organised in a fairly decent enviroment and warm seas and pressure is down to 975mbs, also its definatly getting more organised now on satilite images with a fairly impressive structure, won't be that long before it pops a eye I'd have thought.

    Using the forecast from the GFS...

    http://www.wetterzentrale.de/topkarten/fsavnaus.html

    And the current sea surface temperatures...

    http://www.weather.unisys.com/archive/sst/sst-060319.gif

    (change the 19 to day after relative to today)

    Using those sources, i would suggest that Tropical Cyclone Wati will be at least category 3 at landfall due to sea surface temperatures of 30C.

    Using the GFS, i expect Tropical Cyclone Wati to wobble in a westerly to north westerly direction until Wednesday evening when i expect a wobble in a westerly to south westerly direction before a movement west through thursday before a movement in a westerly north westerly direction during Friday, i expect landfall on Friday night or saturday morning somewhere between Cairns or Townsville, as i have said before, Tropical Cyclone Wati will be at least category 3 at landfall, i will make a proper strength forecast once i have found a wind sheer map for the area.

    Bit of a strange system this one. When it first formed, it looked good (i mean good as in impressively forming). Then he/she kind of declines*, and the track forecasts make it do a u-turn. Now nobody really knows. The BoM don't seem too sure, tbh.

    I suspect it won't be long before an eye forms: http://www.nrlmry.navy.mil/tc_pages/tc_home.html

    *Wati was named by Fiji and not the BoM. Apparently Wati is a bloke in Fiji, but a women in Oz :unsure:

    Surely in this christmas pudding, a cyclone can't be a tranny?? :unsure:

    For 11pm EST on Wednesday the 22nd of March 2006

    At 11pm EST Wednesday, Severe Tropical Cyclone Wati, category 3, with central

    pressure 955 hPa, was located over the central Coral Sea near latitude 18.0

    south, longitude 153.9 east, which is about 610 km northeast of Mackay. The

    cyclone has recently remained almost stationary.

    Severe Tropical Cyclone Wati should remain near stationary over the next 12

    hours while maintaining its intensity, and is subsequently most likely to adopt

    a general southerly track over the following few days, in response to an upper

    trough approaching from the west, and a building mid-level ridge to the east of

    the cyclone. Although this is the most likely scenario, there remain some

    subtleties in the surrounding flow, and there is a small chance the cyclone may

    remain slow-moving, and edge slightly closer to the central Qld coast.

    The combination of the cyclone and a large high in the Tasman Sea is expected to

    produce strong winds and large seas off the coast between Bowen and Fraser

    Island.

    The next bulletin will be issued by 5am Thursday.

    south, longitude 154.0 east, which is about 750 km north of Fraser Island. The

    cyclone has recently remained almost stationary.

    Severe Tropical Cyclone Wati should now begin a southward track which will be

    roughly parallel to the Queensland coast The combination of the cyclone and a

    large high in the Tasman Sea is expected to produce gales and large seas off the

    southern and Central Coasts.

    The next bulletin will be issued by 11am Thursday.

    A clear pinhole eye has formed in the north east corner of Tropical Cyclone Wati and with weak sheer to the north, we can expect intensification, i expect intensification of a strong category 4 or weak category 5 Tropical Cyclone.

    For 0500 EST on Friday the 24th of March 2006

    At 5am EST Thursday, Severe Tropical Cyclone Wati, Category 3, with central

    pressure 950 hPa, was located over the central Coral Sea near latitude 20.3

    south, longitude 157.1 east, which is about 630 km northeast of Sandy Cape on

    Fraser Island. Wati has recently been moving to the south southeast at about 14

    kilometres per hour.

    Severe Tropical Cyclone Wati is expected to maintain a southeastward track,

    which is roughly parallel to the Queensland coast, with only slight, if any

    weakening in the short term. The combination of the cyclone and a large high in

    the Tasman Sea is expected to produce gales and large seas off the Capricornia

    and southern Queensland coasts over the next few days.

    The next bulletin will be issued by 11 am Friday.
