Northern Territory flooding from ex-Tropical Cyclone Narelle and ongoing riverine threats in March 2026
Consensus Summary
The Northern Territory is facing severe flooding in early March 2026 after ex-Tropical Cyclone Narelle dumped heavy rain, causing widespread riverine flooding and damaging homes, infrastructure, and communities. The Katherine River experienced its worst flooding in nearly 30 years, peaking at 19.2 metres on March 7, 2026, inundating homes and businesses, while Adelaide River and remote communities like Numbulwar, Palumpa, and Daly River also suffered significant flooding. Evacuees were relocated to Batchelor education facilities, and boil water alerts were issued for multiple towns. The Bureau of Meteorology issued major flood warnings for several river systems, including the Roper, Waterhouse, and Daly Rivers, with some areas still under prolonged flooding as of late March. Residents in Katherine and surrounding areas remain on edge as the Katherine River is forecast to reach major flood levels again, though forecasts suggest it will not surpass the devastating peak of 19.2 metres. Small businesses and residents are seeking financial relief, while emergency services continue to urge caution against floodwaters. The NT government and federal authorities are coordinating efforts to support displaced communities and aid recovery, though delays in power and infrastructure restoration have left some residents frustrated. The wet season has already seen seven severe weather events, with climate concerns raised by affected residents.
