Issued at 1:59 pm CST on Friday 24 December 2021 Flood Watch Number: 1


A tropical low is developing to the north northwest of the Tiwi Islands. It is expected to strengthen as It moves south and is expected to be close to the Tiwi Islands and west coast of the Top End during Saturday and Sunday. The system may cross the west coast of the Top End later on Sunday, then track east southeast across the Top End.
Heavy rain is likely to develop across the Tiwi Islands and Cobourg Peninsula tonight, and extend to the northern Daly District and northwest Arnhem District during Saturday.

Most of the Top End catchments are relatively dry, however some of the area has been wetting up from the recent showers and storms.

Daily rainfall totals over the Tiwi Islands, northern Daly District and northwest Arnhem District on Saturday are expected to be 50-100mm with isolated totals of 150-200mm about the coast. These falls are expected to extend throughout the Daly District and across the north of the Arnhem District on Sunday and throughout the Top End on Monday.

Significant rises in streams and creeks are expected throughout the flood watch area from Sunday afternoon and many roads may become impassable and may isolate some communities and homesteads.

A tropical cyclone advice is current for parts of the Top End west coast.
