Northern Territory flooding from ex-Tropical Cyclone Narelle and riverine impacts in March 2026

1 hours ago6 articles from 1 source

Consensus Summary

The Northern Territory is facing severe flooding from ex-Tropical Cyclone Narelle, which dumped over 200mm of rain on Adelaide River and triggered riverine flooding across multiple catchments. The Katherine River, already inundated in early March when it peaked at 19.2 metres—causing the town’s worst flooding in 28 years—is expected to reach major flood levels again, though forecasts suggest it will not surpass the previous peak. Residents in Katherine, including businesses like George Pikos’s pizza restaurant, are exhausted from consecutive disasters, with sandbags still in place despite initial relief after warnings were downgraded. The Daly River and Nauiyu communities remain under prolonged major flooding, while Adelaide River and Beswick/Wugularr also experienced localized inundation. Emergency services, including interstate volunteers, are on high alert, with road closures on the Stuart Highway and boil water alerts still active in remote areas. The NT government has activated Personal Hardship Payments and requested ADF support, while displaced residents from Numbulwar and Palumpa are being relocated to Batchelor. Locals like Trent de With praise the town’s preparedness with 15,000 sandbags, but uncertainty lingers as wet season conditions persist, with the BOM warning of further rain and potential river rises.
