The northern rivers is in the path of an east coast low, which is likely to persist for several more days, according to the Bureau of Meteorology (BOM).
The BOM has now withdrawn a minor flood warning for the Brunswick River but issued one for the Wilsons River.
Up to 90 millimetres of rain fell to 8am this morning over the Brunswick River valley but the BOM says this has now eased.
By contrast, some 210mm fell over the Wilsons River catchment in the 12 hours to 3pm.
The BOM is forecasting further heavy rain for the next 48 hours and says that at this stage ‘it is not possible to predict flood peaks because of uncertainty over how much more rain will fall.’
A low-pressure trough over western New South Wales is forecast to weaken today as a high-pressure system over the Tasman Sea extends a ridge along parts of the coast.
But another trough is expected to develop and deepen off the northern coast in the latter half of this week, bringing ‘significant rainfall to the northeast of the state’, the BOM says.
Rainfall has eased since 10 am this morning, however, further rainfall is forecast over the next 48 hours which could produce further river level rises.
River levels at Mullumbimby are expected to peak below the minor flood level.
The situation is being closely monitored and revised warnings and predictions will be issued if necessary.
Minor flooding is predicted along the Wilsons River at Lismore, which is likely to reach the minor flood level (4.20 metres) on Wednesday night.
