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.

  • 10. SOME GOOD NEWS • - - - SO, 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.
  • 11. SOCIO-ECONOMIC IMPACTS • Impacts were comprised mainly of power outages, downed trees, damaged houses, and flooding from the heavy rainfall, but NO DEATHS yet. • Large parts of the 1,000 strong Aboriginal community of Hope Vale and Cooktown, population 2,400, lost power.
  • 12. REMEMBERING CYCLONE YASI
  • 13. CYCLONE YASI STRCK NORTHERN QUEENSLAND STATE, AUSTRALIA The CAT 5 monster storm made landfall with winds gusting to 300 km/hr FEBRUARY 2-3, 2011
  • 14. CYCLONE YASI: FROM A TROPICAL DISTURBANCE (JAN 25) TO A CAT 5
  • 15. CYCLONE YASI NEARING LANDFALL: FEBRUARY 2, 2011
  • 16. 500 KM (300 MI) WIDE CYCLONE YASI: FEBRUARY 2, 2011
  • 17. CYCLONE YASI LANDFALL FORECAST: FEBRUARY 2, 2011
  • 18. Cyclone Yasi made landfall at Mission Beach around midnight, about 100 kilometers north of Ingham, as a category 5 storm
  • 19. The cyclone struck north of the area in Queensland that had already been severely impacted by flooding a month earlier in January.
  • 20. QUEENSLAND WAS RECOVERING FROM FLOODS IN JANUARY
  • 21. With an “eye” by itself over 100 km wide, this storm was the worst cyclone in Australia's history.
  • 22. WIND PENETRATING BUILDING ENVELOPE CYCLONES UPLIFT OF ROOF SYSTEM FLYING DEBRIS STORM SURGE IRREGULARITIES IN ELEVATION AND PLAN SITING PROBLEMS FLOODING AND LANDSLIDES CAUSES OF DAMAGE “DISASTER LABORATORIES”
  • 23. YASI’S INITIAL SOCIOECONOMIC IMPACTS • Roofs torn off houses • Trees uprooted • Thousands without power • Storm surge of up to 2 meters • Up to 700 mm of rain in 1-2 hours
  • 24. SOCIOECONOMIC IMPACTS • 10,000 people evacuated over a 2-day period to 20 evacuation centers
  • 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. 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. 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.
