RENEWED AND INCREASING FLOOD RISK FOR THE CARPENTARIA COASTAL RIVERS AND CENTRAL PARTS OF NORTHERN TERRITORY

Ex-Tropical Cyclone Megan is over the northern Barkly District and will move westwards through the NT over the remainder of the week. Heavy to intense rainfall will remain a threat with the system, primarily over its southern flank.

Catchments in the Flood Watch area are relatively wet and responsive to rainfall, and river levels remain elevated in parts of the Flood Watch area.

Isolated rainfall totals up to 100 mm were recorded across the Flood Watch area in the 24 hours to 9:00 am Wednesday following several days of heavy falls.

Rain and storms with isolated heavy falls are forecast over the next few days. Widespread daily totals of 60-120 mm are possible during the next few days across the Flood Watch area. Isolated heavy falls in excess of 200 mm are possible, with the heaviest totals likely to occur to the south of the system.

The recent observed rainfall is causing flooding impacts, and with further rainfall forecast, impacts will be become more widespread and severe over the coming days. Flood impacts may include road closures, including primary and secondary highways, and isolation of communities and homesteads. Check road conditions before travelling.

A Major flood warning for McArthur River and a Moderate Flood Warning for the Daly River are current.
