Three cyclones, actually. Cyclone Bianca is threatening to hit Perth, Bunbury and Busselton, possibly weakening to a category one.
Bianca is not expected to be as bad as Cyclone Alby which hit Perth in 1978. Alby claimed five lives and caused widespread damage in the Perth metropolitan area.
Before the rain comes the wind, and ironically the first danger could be fire from the high winds.
Does anyone know how often Perth experiences cyclones? I recall one a few years ago that started in the Coral Sea, I think, possibly the Gulf of Carpentaria, which headed west and ended up giving Perth a dousing, probably as a rain depression.
Meanwhile Cyclone Anthony re-formed into a category one storm and is currently about 950 kilometres north-north-east of Townsville.
Forecaster Greg Connor says it is likely to cross the coast between Cooktown and Mackay sometime early Monday morning.
“We do expect it to intensify. It’s probable that it will get to category one or two, but there is the possibility it will get to category three before it gets to the coast,” he said.
The Brisbane Times story shows the possible path:
According to the Courier Mail:
The good news for sodden central and southeast Queensland areas is that Anthony is expected to be mainly confined to the tropics.
As it dissipates, it is expected to track southwest across the state, bringing rain to western parts and raising the spectre of more flooding for country towns already hit.
[Weather bureau forecaster Ben] Annells said Anthony was not a large system and was fast moving.
“While it will have plenty of rain in it, we are not expecting many hundreds of millimetres simply because it is not expected to sit still in one place,” he said.
“When they are slow moving is when they tend to drench an area.”
Meanwhile, it is feared a tropical low about 1500km northeast of Fiji, expected to be named Yasi, could build into a category four cyclone and hit north of Gladstone on Thursday.
All this while Anna Bligh:
launched a $10 million advertising blitz in an attempt to reinvigorate the state tourism industry suffering from extensive negative publicity about weather and natural disasters.
Tourists would rather watch our weather from afar, it seems.
On AGW, yes, we have a La Niña and a negative Indian Ocean dipole, giving warm waters in the Timor and Coral seas. But the Australian sea surface temperature was the warmest on record for 2010 and the decade 2000-2010:
Over and above natural changes in the weather systems, there is more moisture, more heat and energy in the atmosphere.
