Tropical Cyclone Ului : March 2010
« on: 13 March 2010, 10:49:06 AM »
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.

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?

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?.

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.
