The Bureau of Meteorology said the trough moved south, dumping about 100mm across the Katherine region during the weekend, and is now near the base of the Top End, “
“A tropical low is located within the monsoon trough between Borroloola and Katherine,” a bureau spokeswoman said.
“As the low is slow moving, it is expected to bring widespread rainfall totals of around 50mm today, with isolated heavy falls of 100-150mm which may lead to localised flash flooding
“Following heavy rainfall in the Katherine area on Sunday evening, the Katherine River at Nitmiluk Centre peaked at 4.34m at around 3.30 this morning, and is now falling.”
“Whilst flooding is not expected in the township of Katherine in the short-term, continued monsoonal rain may lead to renewed river level rises later this week,” the spokeswoman said.
The monsoonal flow from the north is forecast to continue for the remainder of the week, with 7-day widespread rainfall totals forecast to be in excess of 400mm in coastal areas and 100 – 200mm inland.
Widespread rainfall totals during the past three days were in the 50-150mm range for most of the Top End, with more than 250mm totals in some north coast and in the south west Gulf of Carpentaria.
Three-day totals: Darwin Airport 137mm, Stokes Hill 76mm, Wagait Beach 126mm, Milingimbi 241mm, Ngayawili 335mm, Bing Bong 397mm and Centre Island 398mm.
