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.

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
