The last radar image from Willis Island added below. The last radar image is truly striking.
Also, see below for the differences between the Australia hurricane scale and the familiar Saffir-Simpson scale used in the USA. They are not equal.
From Australia’s BoM, time to “get outta Dodge” as they say:
SEVERE TC YASI IS A LARGE AND VERY POWERFUL TROPICAL CYCLONE AND POSES AN EXTREMELY SERIOUS THREAT TO LIFE AND PROPERTY WITHIN THE WARNING AREA, ESPECIALLY BETWEEN CAIRNS AND TOWNSVILLE.
THIS IMPACT IS LIKELY TO BE MORE LIFE THREATENING THAN ANY EXPERIENCED DURING RECENT GENERATIONS.
DAMAGING WINDS with gusts to 90 km/hr that are currently developing on coastal islands, are forecast to develop about the coast by late morning and about the tropical interior overnight.
Between Cape Tribulation and Ingham these winds will become DESTRUCTIVE with gusts in excess of 125km/hr during the afternoon
and early evening and VERY DESTRUCTIVE with gusts up to 300 km/hr between Cairns and Ingham during the evening as the cyclone approaches and crosses the coast. These VERY DESTRUCTIVE winds can also occur on the seaward side of hills to the north of the cyclone and are also forecast to reach the Atherton Tablelands.
TOP PRIORITY TROPICAL CYCLONE ADVICE NUMBER 14 Issued by the Bureau of Meteorology, Brisbane Issued at 1:53pm EST on Wednesday the 2nd of February 2011 A Cyclone WARNING is current for coastal and island communities from Cape Flattery to Sarina, extending inland to Julia Creek and to the area west of Croydon. A Cyclone WATCH is current for the remaining inland parts west to the Northern Territory border and north of Winton. The Cyclone WARNING from Cape Melville to Cape Flattery has been cancelled. At 1:00 pm EST Severe Tropical Cyclone Yasi, Category 5 was estimated to be 345 kilometres east of Cairns and 360 kilometres northeast of Townsville and moving west southwest at 35 kilometres per hour. SEVERE TROPICAL CYCLONE YASI IS A LARGE AND VERY POWERFUL TROPICAL CYCLONE AND POSES AN EXTREMELY SERIOUS THREAT TO LIFE AND PROPERTY WITHIN THE WARNING AREA, ESPECIALLY BETWEEN CAIRNS AND TOWNSVILLE. DURING THE EVENING, THE VERY DESTRUCTIVE CORE OF CYCLONE YASI WILL CROSS THE COAST BETWEEN CAIRNS AND INGHAM, ACCOMPANIED BY A DANGEROUS STORM TIDE SOUTH OF THE CYCLONE CENTRE. Tropical Cyclone Yasi, CATEGORY 5, will continue to move in a west-southwesterly direction. The cyclone is expected to cross the coast between Innisfail and Cardwell close to midnight. Coastal residents within the warning area, and particularly between Cairns and Proserpine including the Whitsundays, are specifically warned of an EXTREMELY DANGEROUS SEA LEVEL RISE [i.e. storm tide] as the cyclone approaches, crosses the coast and moves inland. The sea is likely to steadily rise up to a level which will be VERY DANGEROUSLY above the normal tide, with EXTREMELY DAMAGING WAVES, STRONG CURRENTS and FLOODING of low-lying areas extending some way inland. People living in areas likely to be affected by this flooding should take measures to protect their property as much as possible, and be prepared to follow instructions regarding evacuation of the area if advised to do so by authorities. DAMAGING WINDS with gusts to 90 km/hr are currently affecting the coast and islands, and are forecast to spread into the tropical interior overnight and west to Julia Creek during Thursday. Between Port Douglas and Ayr these winds will become DESTRUCTIVE with gusts in excess of 125 km/hr developing during this afternoon and early evening, spreading into the tropical interior overnight. VERY DESTRUCTIVE winds with gusts up to 290 km/hr are expected to develop between Cairns and Ingham during the evening as the cyclone approaches and crosses the coast. These VERY DESTRUCTIVE winds will also occur on the seaward side of hills to the north of the cyclone and also affect the Atherton Tablelands. Due to the large size of the cyclone, people in the path of the VERY DESTRUCTIVE WINDS are likely to experience these conditions for about 3 to 4 hours. Winds are forecast to gradually ease about the east coast during Thursday morning as the cyclone moves inland. FLOODING RAINS will develop from Cooktown to Sarina during the afternoon and then extend inland overnight. People between Cape Flattery and Sarina, extending inland to Julia Creek and to the area west of Croydon should complete preparations quickly and be prepared to shelter in a safe place. - Boats and outside property should be secured. - For cyclone preparedness and safety advice, visit Queensland's Disaster Management Services website [www.disaster.qld.gov.au] - For emergency assistance call the Queensland State Emergency Service [SES] on 132 500 [for assistance with storm damage, rising flood water, fallen trees on buildings or roof damage].

It is not officially the Atlantic Hurricane Season yet, however TheWeatherSpace.com is monitoring a disturbance in the Southern Caribbean this week and into next week.
"It is early to tell but ongoing thunderstorm activity associated with a tropical wave developing down there will drift northward through Cuba this and next week toward Florida", said TheWeatherSpace Senior Meteorologist Kevin Martin. "The weak ridging in the southeast may promote development into something stronger over the next week".
Should Martin be correct, Florida will need to keep an eye on future updates out of TheWeatherSpace.com.
