A low pressure system and a final pulse of the monsoon trough in the
tropics has brought some heavy rainfall totals throughout the Easter
holiday in the NT.
In the 24 hours to 9am Monday, Katherine gained more than 120mm of
rain, with three times the monthly average dumping in one night. This
makes it the heaviest March rain in 29 years of records. Out of the 31
days in March, it rained in Darwin for 28 of them. Over the last five
days in Darwin a total of 153.6mm has fallen.
While in Maningrida, 100mm fell in 24 hours to Monday. Over the last
five days, over 550mm has fallen, making it the wettest five day spell
in at least ten years.
A major flood warning has been issued for the Waterhouse River near
Beswick Bridge as well as a minor flood warning for the Katherine
River Gorge Rd. Flood advice is also in place for residents of the
Arnhem, Darwin-Daly, northern Roper-McArthur and northern Victoria
The low pressure system which has been the main contributor to the
rainfall this week will contract to the west, causing a gradual easing
of rain. At this stage it is too early to tell when it will be safe to
leave the umbrella at home for northern NT residents.
