Summary
[edit]DescriptionFlooding in Northwest Australia (MODIS).jpg |
English: Starting on December 30, 2022, remnants of Tropical Cyclone Ellie brought days of torrential rain and wind to northern Western Australia. The deluge caused the Fitzroy River to swell to record-high levels, inundating floodplains and isolating several riverside communities.
Severe flooding is evident in the false-color image acquired on January 9, 2023, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. Water appears light to dark blue; vegetation is green and bare land is brown. NASA’s Worldview App permits an easy comparison between today’s image and one acquired by Aqua MODIS on December 17, 2022. To see the stark difference in the same area pre- and post-flood, simply click here Flooding is common along rivers of the Kimberly region in Western Australia. But the amount of water delivered by the ex-tropical cyclone was exceptional. From December 30, 2022, through the first week of January 2023, rainfall totals across the region ranged from 200 to 500 millimeters (7.9 to 19.7 inches). As a result, the Fitzroy River’s flow rate reached about 60,000 cubic meters per second—well above the 23,000 cubic meters per second usually seen during floods on this river, and one of the highest flow rates ever observed in any Australian river. Australia’s Bureau of Meteorology reported that the river’s water levels near the town of Fitzroy Crossing peaked at a record-high 15.81 meters on January 4. That’s almost two meters higher than the previous record reached during flooding in 2002.The floodwater left many roads and bridges impassable, isolating Fitzroy Crossing, Derby, Broome, and many of the region’s remote indigenous communities. Tropical Cyclone Ellie first hit Australia’s Northern Territory as a Category 1 storm on December 23, 2022. It then weakened into a tropical low before moving into Western Australia on December 30. By January 7, 2023, the former tropical cyclone had moved back into the Northern Territory and further weakened as it moved toward Queensland. The recent flooding in Western Australia follows several severe flooding events that have occurred in eastern Australia during three consecutive years of La Niña conditions. La Niña usually brings wetter-than-average conditions to the country. 2022 was Australia’s ninth-wettest year on record. |
