Keeping track of Sandy a nightmare

Written By Unknown on Kamis, 07 Maret 2013 | 00.04

QUEENSLAND is expected to have its second cyclone of the season today when a major low 770km northeast of Townsville reaches cyclone strength.

But trying to work out which way Cyclone Sandra will head is proving a nightmare for forecasters.

It is expected to remain well offshore at least until the weekend but computer models cannot agree if it will merely head to sea or whether New Caledonia, Fiji or Australia will feel its brunt.

Two major weather systems are steering the big storm but it is not clear which will be the major player in its course.

If a strong northwest monsoon flow prevails over a southeasterly high, the storm will be pushed away from Australia. If the position is reversed it could head towards the coast.

Weather Bureau forecaster Pradeep Singh said Coral Sea cyclones had a reputation for erratic patterns.

"Some behave," he said. "Yasi did. It had a reasonably consistent track but some you see have really erratic paths.

"They do all sorts of things. They go north, go south, do loops and this one might live up to the reputation."

The Early Warning Network, a commercial organisation that sends out severe weather alerts, has produced a map showing computer modelling tracks.

It's a confusing array of directions.

Network manager Kerry Wainright said major US, European and Australian models differed, showing just how difficult it was to forecast Coral Sea cyclones.

"Everyone's got a different outcome," Mr Wainright said. "Some have it coming down near Brisbane, others have it crossing the coast in the north and others have it going away completely.

"Things should crystallise over the next 48 to 72 hours. I hope it doesn't come this way. We've had enough."

Communities Minister Tracy Davis said Natural Disaster Relief and Recovery Arrangements had been activated in the Western Downs local government area, including Dalby after a weekend flood.

"Queensland has been hard hit yet again by Mother Nature, with very heavy rain causing flooding throughout the southwest," Ms Davis said.

A high is producing gale force winds and a big swell, with waves to 7m recorded by an Environment Department buoy off North Stradbroke Island yesterday.

Mr Singh said although showers would remain along the coastal strip, the low would draw moisture away from Australia for the next few days, disappointing graziers who were desperate for rain.

Meanwhile, the body of a Leyburn resident, 64, who went missing in floods last week has been found in the Condamine River south of Toowoomba. Police have not found his four-wheel-drive vehicle.
