There appears to be a new threat heading for the East Coast of QLD, with 2 tropical storm systems approaching over the next 3- 4 days. With the recent rain in QLD and combined dam levels at 96% and rising, it could pose a new flood threat for us. Worth while monitoring these two.
BOM have issued a moderate chance of a cyclone forming on Sunday and Monday at this stage.

Ului has intensified last night into a Cat.4 storm and is approx. 266 kilometers (162.4Deg E) from entering Australian waters (that is 160 deg East)
Latest update is
TROPICAL CYCLONE ULUI CENTRE 945HPA CATEGORY 4 LOCATED NEAR 13.0 SOUTH 162.4
EAST AT 131800 UTC.
POSITION FAIR.
REPEAT POSITION 13.0S 162.4E AT 131800 UTC.
CYCLONE MOVING WEST AT 06 KNOTS.
EXPECT SUSTAINED WINDS OF 100 KNOTS CLOSE TO THE CENTRE INCREASING TO 115 KNOTS
IN THE NEXT 18 TO 24 HOURS.

Wow this cyclone is huge and so is the 1 behind it. Does anyone think it may have potential to hit as far south as Byron Bay? Even the tail?

and here is a second image showing both of the cyclones. they look scary
-
Man im kinda freaked out by the satellite!!! Its still moving WSW to WNW as usual!! Looks like it going back to category 5 again tomorrow.
GASP is now on board for this 900hpa TC Ului to slam on Townsville direct hit!! Im so nervous......
PS: This thread need to update the topic by adding 'Severe' due to current category of 4!

Cyclone Thomas that John was mentioning had an impact on Fiji last night. Reports indicate that it was the worst storm to hit Fiji in a decade.
I also agree with you John, JTWC have been on the ball with Ului, where as BOM has not made a firm stance, which is understandably hard to do with so much involved and so many possibilities. BOMS latest reports state:
It is expected to adopt a more south to southeasterly track tonight, which it
should maintain until later in the week. Its longer term forecast track is still
uncertain but at this stage the most likely scenario is for Severe Tropical Ului
to turn in a more west to southwesterly track and move closer to the Queensland
coast during Friday and over the weekend.
WZ have Ului making possible landfall on Sunday, they state:
Sunday 22:00 EDT
Tropical Cyclone Ului may cross the coast or move south along the coast, generating rain and gales south of the tropics and into northeast NSW. A trough will bring a cooler change to NSW. A high will keep most of inland NSW, VIC, TAS and SA dry in gusty southeasterlies.
Their Synoptics for sunday as posted
It is a case of watching and seeing at this stage.
-
The latest track map and advice from BOM, suggests that maybe over the weekend there is a possibility that Ului will cross the coast.
One of the concerns is the from looking at the accumulated precipitation forecasts.The 18Z /120 hr run ( 5 day)shows a bulls eye of 450 mm of rain for the next 5 days north of Rockhampton, the rest of the 120 hr run shows around 100 mm for Brisbane and south of here. The 180 hr run is of interest as well for Brisbane. The areas surrounding Brisbane have approx 275 mm totals and South of Bunderberg 425 mm. If the models hold true, then there is a very high chance of severe flooding down the Capricornia Coast, Brisbane and Northern NSW
-
Well Ului has made a nice Thread on Weatherzone forums so far 150 Pages oh my goodness it hasent even hit us yet. Below is the accumulated precipitation that has now vhaged to 3 main cores with 300+mm near Ballina/ Byron. 2nd image down shows the current Cyclones position and Proposed track ( except i added more range of arrows :-) and the 3rd one down is the 850MB shear map. Looks like a direct hit to central QLD by near 10pm Sunday?.

TROPICAL CYCLONE ADVICE NUMBER 1
Issued by the Bureau of Meteorology, Brisbane
Issued at 10:56am EST on Thursday the 18th of March 2010
A Cyclone WATCH has been declared for coastal areas from Cardwell to Yeppoon.
At 10:00 am EST Severe Tropical Cyclone Ului, Category 3 was estimated to be
1140 kilometres northeast of Mackay and
1310 kilometres east of Cairns and
moving south southwest at 6 kilometres per hour.
The cyclone is expected to remain about the same strength.
Severe Tropical Cyclone Ului is expected to begin moving in a south-westerly
direction tonight towards the Queensland coast.
On current predictions the most likely scenario is for the cyclone to cross the
coast Sunday morning between Cardwell and Mackay. However, it is important to
understand that some uncertainty remains in this outlook period.
DAMAGING winds should develop between Cardwell and Yeppoon during Saturday as
the cyclone approaches the coast.
The windy conditions over much of the Queensland east coastal waters will
continue due to the tight pressure gradient generated by a combination of a high
pressure system situated in the Tasman Sea and Severe Tropical Cyclone Ului.
Seas and swell are expected to increase along much of the Queensland east coast
and produce dangerous surf conditions on the exposed coasts.
People between Cardwell and Yeppoon should consider what action they will need
to take if the cyclone threat increases. If you are unsure about the actions to
be taken, information is available from your local government or local State
Emergency Service.
Details of Severe Tropical Cyclone Ului at 10:00 am EST:
.Centre located near...... 15.0 degrees South 157.8 degrees East
.Location accuracy........ within 20 kilometres
.Recent movement.......... towards the south southwest at 6 kilometres per hour
.Wind gusts near centre... 205 kilometres per hour
.Severity category........ 3
.Central pressure......... 960 hecto Pascals
Please ensure that neighbours have heard and understood this message,
particularly new arrivals or those who may not fully understand English.
The next advice will be issued by 5:00 pm EST Thursday 18 March.

Its currently light winds with sprinkles so its the 'calm before the storm'! The track map showing it still heading for Townsville so note that the intensity may upgrade to category 4 sometime that i wouldnt be surprised!
-
Just did some shopping with Kathyrn this evening at Stockland Woolies. Its getting more packed when i got there and people are well focused to shop at Woolies than other retailers when are open at the same time.
I also refill too.
It getting very windy here now, i think The Strand probably gale wise!!

Hi all,
Everytime I look at the satpic of this beast, it looks like it is losing its strength, and getting weaker. The eye has now disappeared and even though it is listed as severe cat 3, it looks more like a cat1 or cat2. I don't think this is going to be anywhere near as bad when it hits the coast over the weekend.

Still staying as category 2 for landfall. Not good enough for the field trip tomorrow @ Giru!??

Ului is on course to make landfall some time tomorrow, Sunday21/03/10. Currently a cat 2 System, there is a slight chance that it will build back to a cat.3 before crossing the coast between Ayr and Sarina. I thought it was going to be slightly further south when I first starting observing the storm. It still will carry a bit of a punch when it hits, so it is important to keep up to date with emergency warnings.
Latest Tech bulletin states
REMARKS:
Following a period of weakening due to northwesterly wind shear, Tropical
Cyclone Ului has shown increased organisation in the last 6 hours with LLCC now
under deep convection.
Dvorak analysis gave an ambiguous curbed band of 0.9 wrap yielding DT of 3.5.
MET of 4.0 with PAT of 3.5. Hence FT/CI = 3.5.
AMSU estimates suggest higher wind speeds are possible. Surface observations a
large area of storm force winds.
Models remain very consistent with the forecast track continuing west southwest
today and crossing the coast between Ayr and Sarina early on Sunday morning,
steered by the mid-level ridge to the south. As a result, there is a higher than
normal confidence in the track forecast.
Forecast intensity is based on some development continuing, into weak category 3
near landfall. However models do not suggest further intensification so some
doubt remains on the system's reponse to shear.
-
Ului has now re intensified to CAT3, warning signals are now being used in the broadcast. The situation as you can understand is now serious. Latest update.
Media: Transmitters serving the area between Cardwell to Yeppoon and inland to
Hughenden, including Charters Towers and Clermont are requested to USE the
Standard Emergency Warning Signal before broadcasting the following warning.

From the forecast track, looks like it could hit Prosepine head on...
Take care all up that way, this beast has gotten nastier by the minute!

As John pointed out, there is a high probability of a large tidal surge, to add to that, currently the wave rider Bouy at Bailey Islet, Mackay have registered a Hmax height of 7.5 meter waves.
-
The Wave rider Buoy at Bailey Islet, Mackay registered a 9.5 meter Hmax during the peak of the storm with a 5.7 meter Hsig. At this stage I have not heard of the damage reports as is still probably pretty dangerous to survey, but over the next couple of hours we should start receiving the reports.
Currently, after crossing the coast Ului is still making her way inland as a Cat 2 cyclone.
Update from BOM this morning.
At 5:00 am EST Tropical Cyclone Ului, Category 2 was estimated to be
45 kilometres south southwest of Bowen and
135 kilometres northwest of Mackay and
moving west southwest at 23 kilometres per hour.
At 6:00 am EST the cyclone is estimated to be
15 kilometres north northwest of Collinsville and
82 kilometres west of Proserpine.
The centre Tropical Cyclone Ului is currently just west of Collinsville, and
continuing to move further inland. The cyclone is expected to rapidly weaken
later this morning.
DESTRUCTIVE wind gusts to 155 km/hr are expected to continue affecting the
coastal and island communities between Bowen and Seaforth for the next hour or
so.
DAMAGING winds are expected in areas between Ayr and Sarina and the adjacent
inland for the next few hours, then gradually ease during the afternoon.
-
It seams Ului dissipated fairly quickly after crossing the coast.
Although as of 4:40 am 22-03-2010 BOM still have a Severe Weather Warning in QLD for heavy rainfall and flooding
for the Central Coast, Capricornia district and for the Central Highlands and Central West north of a line from Taroom to Longreach.
BOM has released data from a trial of the new Emerald Radar earlier than scheduled due to TC Ului
