Tropical Cyclone Yasi is likely to cross Queensland's tropical coast early Thursday morning, according to the Australian Bureau of Meteorology. The potentially dangerous cyclone is exceptionally large in size.
The Bureau of Meteorology's Queensland Regional Director Jim Davidson, says the bureau is closely watching Tropical Cyclone Yasi and has issued a formal Cyclone Watch.

Rampaging across the southern Pacific Ocean, Tropical Cyclone Yasi easily spanned the distance between the Solomon Islands and Vanuatu on Sunday. The Vanuatu Meteorological Service says the cyclone is picking up strength as it veers away from the islands, travelling west towards Townsville in Australia.
At midnight on February 1 local time, the U.S. Navy's Joint Typhoon Warning Center reported that Yasi was roughly 1,620 kilometers (875 nautical miles) east-northeast of Cairns on the Queensland coast.
Yasi was measured with maximum sustained winds of 90 knots (165 kph, 103 mph) and gusts up to 110 knots (205 kph, 126 mph).
The tropical coast is likely to begin feeling the first effects of Yasi on Wednesday morning, with damaging winds starting to impact coastal and island communities as the cyclone approaches.
Authorities are going from door-to-door in northern Queensland ordering people to leave their homes to escape a predicted two-meter (seven foot) storm surge.
Davidson said, "People in the affected area will start to experience gale force winds as early as Wednesday morning, so should be putting their cyclone plans into effect immediately."
Davidson said "TC Yasi is currently rated as a Category 3 cyclone and is expected to continue intensifying as it moves towards the coast over the warm waters of the Coral Sea."
"There is always uncertainty with any weather event but, at this stage, the various models we use to assist our decision making process are consistent in suggesting that TC Yasi will cross the coast somewhere between Innisfail and Proserpine early Thursday morning."

Yasi has the potential to make landfall in Cairns with wind speeds in excess of 100 knots (185 kph, 115 mph), making it more powerful than Cyclone Larry, which devastated the north Queensland town of Innisfail in 2006.
The Joint Typhoon Warning Center predicts that favorable conditions will intensify the storm, which could peak at 125 knots (230 kph, 144 mph).
Queensland Premier Anna Bligh said at a news conference Sunday, "It is a very large rainfall system as well as potentially a very significant cyclone, so we are looking not only at potentially damaging cyclone but more very heavy rainfall which could fall into river catchments and cause further flooding beyond the cyclone. There is likely to be very significant gale force winds."
On the Queensland coast, the Abbott Point coal terminal has been closed, and trains and ferries will not travel until the cyclone has passed. Some 300 schools across northern Queensland will close on Wednesday until further notice. In Townsville, shelters have been opened for people who are either homeless or living in caravan parks.
Unless they are asked to evacuate, emergency officials say residents should stay home. "People who have a home are much safer in their own home and we would encourage people to shelter in place," the premier said.
Although the floods of December and January covered more than half of Queensland, Premier Bligh says emergency officials are ready for this new test.
"Yes we have come through a very difficult time and our emergency resources have certainly been tested in the last couple of weeks," said Bligh, "however I want to reassure people that they have had ample opportunity to replenish themselves and restore supplies. We are not battle weary, we are battle ready, and our highly trained people are well rested and they are ready to respond."
Bligh said, "What we have seen in the last few weeks is an emergency service response that I think is world class and is one that people can have confidence in and rely on in the week ahead."
