The Wilsons River is likely to remain above moderate flood levels today (Monday) as further rainfall in the catchments makes the lowering of river levels a slow process.

Rainfall in the last 24 hours was lower in the southern end of the Northern Rivers. Lismore airport recorded 27.4mm to 8:30am, Ewing Bridge at Corndale 61mm, Dunoon 66mm and Terania Creek 55mm.

Further to the northeast, the falls were a lot higher. Huonbrook 152mm, Goonengerry 129mm, Mullumbimby Creek 105mm, Mullumbimby Upper Main Arm 127mm, Uki 108mm and near the Queensland border Bilambil Heights recorded 272mm.

Christie Johnson, a senior meteorologist with the Burea of Meteorology, said the highest falls were in South East Queensland with Wangawallen (inland Gold Coast) recording 400mm and areas of the Sunshine Coast 350mm.

Unfortunately, the low pressure system is drifting south for most of Monday, meaning there is a very high chance of rain, and heavy rain, which may lead to flash flooding. The easterly winds will turn more northeasterly after midday, which will see less rainfall for Tuesday. Possible showers is the forecast with a 0-7mm range.

Shop owners looking to get back in and trade will be doing so under trying conditions, but no worse than they have faced in the last five days.

Christie Johnson said river levels continue to fall slowly at Lismore, "River levels are likely to remain above the moderate flood level through to Monday evening".

A Severe Weather Warning is current for heavy rainfall for the Northern Rivers. This rainfall may cause renewed river level rises at Lismore from late Monday onwards. The situation is being closely monitored and warnings will be updated as necessary.
