   Flooding in Australia

   A rain-filled tropical low slowly skirted the coast of Western
   Australia in early February 2021, dumping heavy precipitation which led
   to flooding across the region. The Gascoyne Region was particularly
   heavily hit, with the Australian Bureau of Meteorology (BoM) quoted as
   reporting that 176 mm (6.9 in) of rain fell in Carnarvon in 24 hours on
   February 5. On that day, flooding was reported along the Gascoyne River
   at several locations. The Floodlist website reported that dozens of
   people were rescued from the floods in the Gascoyne regions, including
   some by helicopter.

   On February 10, the Moderate Resolution Imaging Spectroradiometer
   (MODIS) on board NASA’s Aqua satellite acquired a false-color image of
   flooding in the Gascoyne region of Western Australia. This type of
   false color image uses infrared and visible light (Bands 7,2,1) to
   enhance the contrast between water and vegetation. Here surface water
   appears blue while deep water appears inky-blue, vegetation looks
   green, and non-vegetated land appears tan. The flooded rivers and
   ephemeral streams clearly stand out against the semi-arid landscape.

   While a single image gives a clear view of the scene at a single point
   in time, it often is informative to be able to compare the changes in
   the same area over time. Thanks to the NASA Worldview App, the
   impressive extent of the flooding can be appreciated by comparing this
   Aqua MODIS image acquired on February 10 to a previous image collected
   by Aqua MODIS on January 20, 2021—before the rains. To view the
