The forecast: Wind gusts of up to 280 kph (175 mph) and heavy rainfall were forecast by the Australian Bureau of Meteorology. Anticipating heavy rainfall, 30,000 were evacuated from low-lying areas known to be susceptible to flooding. Some good news: Wind gusts of up to 280 kmh (175 mph) were forecast by the Australian Bureau of Meteorology, but, Ita weakened to a category 4 storm just before making landfall. AND, Ita’s landfall was along a portion of the coast that is lightly populated. As a result, damage was much less than the $3.6 billion price tag of the last Category 4 cyclone that hit Australia’s Queensland State in 2011 —CYCLONE YASI.

  25. 25. THE BAD NEWS The combination of Yasi’s very heavy rainfall as it moved inland and a very high water table from the January flooding exacer- bated the socioeconomic impacts.
  26. 26. WORST FLOODING IN A DECADE Floodwaters had drained slowly towards the country's northeast coast, filling bulging rivers and inundating at least 22 towns and cities in the cattle and fruit and vegetable farming region.
  27. 27. YASI’s IMPACTS • Socioeconomic impacts for 200 thousand people included: industrial slow-down, evacuations, a plague of snakes and crocodiles, health care problems, missing persons, 35 deaths, and losses of 3.6 Billion.
