Good morning Mr. Black head of the State Emergence Service and fellow volunteers.
Cyclone Yasi began developing as a tropical storm near Fiji on 29th January. The system quickly changed and became a cyclone and was named Yasi at 10pm on the 30th by Fiji Meteorological Service.
Yasi headed in a westward track and rapidly intensified, from a Category 2 at 10am on 31st January and then further to a Category 3 at 7pm that day. Yasi maintained Category 3 intensity for the next 24 hours before being upgraded to a Category 4 late on 1st February. During this time, Yasi started to take a more west-southwestward, so it began to accelerate towards the tropical Queensland coast. As Yasi ripped apart Queensland’s North coast it was became a Category 5 cyclone.
Yasi is not just a cyclone but a brutal storm and because of this there where major rainfalls near and around Yasi. The amount of rain that was recorded was in the 24 hours after Yasi, it was between 200-400mm. These rainfall totals were experienced in the area between Cairns and Ayer; this caused some flooding in these regions. The highest totals were; South Mission Beach at 471mm, Hawkins Creek 464mm, Zattas 407mm.
A natural disaster is the effect of a natural hazard that leads to financial, environmental or human losses. Cyclone Yasi is classified under this as it caused human loss and major financial loss, some figures of money used to help the disaster recovery was $310 million. Some other thing that makes this a natural disaster is that it cannot be controlled by man and is unpredictable.
Tropical Cyclones knew as TC are low pressure systems which develop in the tropics, in the southern hemisphere. They are sufficiently intense to produce sustained gale force winds at an average minimum of 63 km/h. Yasi got up to an amazing 295km/h. These Cyclones rotates in clockwise direction acting like a vacuum. The tropical cyclones are also known as a Hurricane or Typhoon, in the northern
