At 4pm AWST Ex-Tropical Cylone Joyce was estimated to be 55km north of Paraburdoo moving southwest at 21km/h.
Ex-Tropical Cyclone Joyce will continue to move southwest through southern parts of the Pilbara into northern parts of the Gascoyne this evening and then towards northern parts of the South West Land Division on Sunday.
Ex-Tropical Cyclone Joyce will continue to weaken as it moves further inland. It is expected to bring HEAVY RAINFALL that may lead to FLASH FLOODING. Widespread daily totals of 50 to 80mm are expected across the warning area, with isolated heavier totals of up to 130mm possible near the system's centre.
HEAVY RAINFALL that may lead to FLASH FLOODING, and DAMAGING WIND GUSTS to 100 km/h over the central and southern Pilbara, western parts of the Interior, the northern Gascoyne and extending into the central parts of the Gascoyne in the evening.
Heavy rainfall is likely to extend through the southern Gascoyne and into northern parts of the South West Land Division during Sunday as the low continues southwest. However, there is still some uncertainty as to its exact path and therefore where the heaviest rainfall will be.
