Tropical Low 12U

28 January – 8 February 2021

Summary

Tropical low 12U developed over the far north Kimberley and traversed much of Western Australia before moving into the Bight and becoming merged with a mid-latitude system. The low did not develop into a tropical cyclone however gales were present in the southwestern quadrant as it moved south, just offshore from the west coast.

The low produced extended periods of heavy rainfall as it moved over the Kimberley, Pilbara and Gascoyne and caused flooding of roads and rivers across those districts. The Gascoyne River reached moderate flooding level and the main highway north sustained significant damage. As the low moved over the southwest corner on 7 and 8 February heavy rainfall was recorded in many agricultural districts. The rainfall also assisted in extinguishing a severe wildfire that had been raging to the northeast of Perth for many days and that had been responsible for the loss of many homes.
