A powerful tropical cyclone was likely to have crossed Western Australia's remote Pilbara mining region early today, forcing many resource companies to shut down.
quote:Flood victims on storm alert
BRISBANE - Residents of flood-ravaged central Queensland are to get a reprieve from the wet weather in the coming days, but have been put on cyclone watch as a low-pressure system develops off the coast.
The city of Mackay was yesterday continuing a mammoth clean-up after a freak deluge last Friday which damaged thousands of homes.
Extra emergency workers from Brisbane and Cairns were expected yesterday to relieve local volunteers who worked around the clock over the weekend, despite most having their own damaged property to tend to.
Among the relief crew are 12 chainsaw operators as strong winds and the wet combine to bring down trees.
Firefighters will continue the task of assessing up to 3000 homes.
Forecasters said rain and wind on the central and north coasts would ease in the coming days, but the low-pressure system had the potential to develop into a tropical cyclone.

Heavy rain and winds in Northland have cut power to around 800 homes and rising flood waters have made some roads impassable in the region.
Lines company Vector said electricity problems were at their worst at Te Hana, north of Wellsford, where 500 homes had been blacked out.
The MetService this morning issued a severe weather warning advising people to look out for rapidly rising waterways as heavy falls spread to Auckland and Coromandel Peninsula.
Police from the township of Kaeo this afternoon said Dip Road and Hospital Road were reported to be under a metre of water, while SH10 at Whangaroa Road is expected to also become impassable.
Maston Road in Paihia had been washed away and the road was closed. Detours were in place.
"Local residents are warned to avoid travel in the affected areas," said Mr Brooker.
The weather conditions also played a part in a serious crash on State Highway 1 at the Dome Valley.
Police believe a driver lost control and their vehicle slid across the road, running head-on into two cars coming the other way.
One woman was badly hurt and another person suffered moderate injuries. The road has reopened but police have advised caution.
The MetService said today's heaviest falls would be in the hills north of Whangarei where some 70-90mm of rain was expected between 9am and 9pm, with falls reaching 15mm per hour at times.
Northern parts of Auckland could expect 50-70mm of rain.
Heavy rain is also expected to hit the South Island, falling in the ranges of northwest Nelson, Fiordland and the Westland ranges south of Otira.
From Saturday night the rain in the south should ease, but the MetService said another front would move onto the South Island on Sunday afternoon - bringing more heavy rain to the West Coast.
Meanwhile, the heavy weather caused some damage overnight.
Three boats were washed off their moorings in Auckland's Waitemata Harbour.
Two were recovered before they could hit rocks but a yacht was washed ashore on Tamaki Drive and holed. It was secured and expected to be left where it was overnight until the weather abated tomorrow.
In west Auckland a man was cut free from his car when it overturned on the slippery roads conditions in Titirangi.
High winds were forecast for motorists driving over the Auckland Harbour Bridge and they were advised to drive with extreme care.
The Coastguard Northern Region advised boaties to stay at home as the harbour surface chopped up.
On Auckland's North Shore, several trees were blown down, causing a minor power cut to parts of Castor Bay and Milford.
Many householders who did not bring in their wheelie bins after yesterday's collection on the North Shore had to take a walk down the road to collect them after they were blown over and took off in the high winds.
The Fire Service reported few road accidents from the slippery conditions overnight but urged motorists to take care.
The weather has caused Auckland's Starlight Symphony at the Domain to be postponed until 7.30pm and the Two Handed Round North Islandyacht race to be delayed until Sunday at 10am.
South of Auckland, the national rowing champs on Lake Karapiro near Cambridge, began on time today although the lake surface was a little rough. The lake was relatively sheltered and rowing was expected to be held for most of the day.

The survivors of a tsunami that killed thousands living on the shores of the Mediterranean in AD 365 called it the "day of horror". Worryingly, history may be due to repeat itself, say geologists who have located the source of the wave.
No one had been able to find evidence pinpointing the earthquake that caused the tsunami, which struck the Egyptian city of Alexandria and the Nile Delta in AD 365. The mainstream view was that a series of quakes had struck the region – cumulatively thrusting a section of western Crete upwards by 10 metres.
Beth Shaw and colleagues at the University of Cambridge carbon-dated a section of corals on the coast of Crete that were lifted clear of the water during the upheavals.
The corals' distribution and identical age revealed that one giant quake must have lifted all of them by 10 metres in one massive push – revealing the tsunami's source.
The only thing that could have generated such a large uplift at that location is an earthquake in a steep fault in the Hellenic trench, near Crete, says Shaw.
Future slips?
The team built a computer model that suggested such movement would have created a 2-metre wave in open water – the same height as that generated by the Sumatran earthquake in 2004 – which would have travelled down to the African shore before crashing over the low-lying Egyptian coast.
Shaw says a further slip in the same part of the fault that caused the tsunami is only likely to happen once every 5000 years. However, other segments of the fault may slip on a similar scale, she says, and this movement could happen every 800 years or so.
"The big unknown is whether the fault that slipped is unique, or one of many contiguous patches that might slip in the future," says Roger Bilham of the University of Colorado in Boulder.
Yo-yo quakes
In another new study, Anja Scheffers at Southern Cross University, Australia, and colleagues reveal geological evidence of five tsunamis that hit Greece in the past 2000 years.
Most were small and local, but in 1303 the same wave hit Crete, Rhodes, Alexandria and Acre in Israel (Earth and Planetary Science Letters (DOI: 10.1016/j.epsl.2008.02.021).
However, Scheffers' co-author, Dieter Kelletat, of the University of Duisburg-Essen in Germany, is not convinced by Shaw's interpretation that a single event uplifted Crete by a full 10 meters in 365 AD. "There is not only a step-by-step movement, but also a yo-yo effect with ups and downs," Kelletat says.
He also warns that much more work is needed to unravel the region's complex geology, citing evidence of sea-level change of more than one metre since Roman times. "We are convinced that there is much more to find," he says.

WENEN - De kans op lawines in Oostenrijk is na het vallen van veel vers sneeuw groot. Dat meldden de lawinewaarschuwingsdiensten zaterdag.
In grote delen van het land geldt gevaarniveau drie of vier wat aanzienlijk of groot lawinegevaar betekent. Er valt veel sneeuw in het alpenland.
In de regio Arlberg viel in de nacht van vrijdag op zaterdag 60 centimeter. Meteorologen voorspellen nog meer sneeuw.
