Northern Territory flooding from ex-Tropical Cyclone Narelle and ongoing riverine impacts
Consensus Summary
The Northern Territory is grappling with severe flooding triggered by ex-Tropical Cyclone Narelle, which dumped over 200mm of rain on Adelaide River and saturated catchments across the Top End. The Katherine River, already swollen from earlier rains, faced a second major flood threat in March, peaking just above the 17.5m major flood levelâ1.6m below the devastating 19.2m peak from earlier this month. Communities like Adelaide River, Daly River/Nauiyu, and Beswick/Wugularr endured prolonged inundation, with homes damaged, roads cut, and boil water alerts issued. Evacuees from remote areas were relocated to Batchelor, while Katherine residentsâstill recovering from the worst flooding in 28 yearsâprepared for repeated disruptions, sandbagging homes and monitoring river levels anxiously. Emergency services, bolstered by interstate volunteers, urged caution as floodwaters receded slowly, with prolonged major flooding expected along the Daly River through March. The NT government coordinated recovery efforts, including financial support for affected businesses and communities, while residents expressed fatigue and frustration over the relentless wet season.
