Expected Conditions
A tropical low in northern Western Australia is feeding rich moisture along a surface trough, combining with an upper trough moving through southern WA. This system is expected to produce heavy rainfall which may lead to flash flooding. Six-hourly rainfall totals between 50 mm and 80 mm are likely in the affected areas.

Heavy rainfall is forecast to develop through the southwest starting late Sunday evening, March 15, 2026, and will continue during Monday. The Bureau of Meteorology expects to issue the next update by 5:00 pm ACST Sunday.
