Although only 19mm has fallen at the Lismore airport and 29mm at Dawson Street since 6pm yesterday evening, significant rainfall in the catchments and further rainfall have forced the NSW SES to advise people in low-lying areas north of Lismore in the Wilsons catchment to STAY INFORMED about possible minor flooding on the Wilsons River.

The advice is also for Nimbin, The Channon, Dunoon, Goolmanagar and Cowongla and surrounds.

Terania Creek recorded 132mm in the last 24 hours, Doon Doon 241mm, Nimbin 87mm, Goonengerry 78mm, and Jiggi 73mm.

The Wilsons River gauge at Lismore is 0.52m and rising. The minor flood level is 4.2m.

The Bureau of Meteorology (BoM) advise that severe weather may continue to cause flash flooding across the region. This rainfall is forecast to continue into the weekend with intense falls possible throughout Friday.

The BoM is forecasting further rain for the rest of Friday, 7-35mm tomorrow and 15-70mm on Sunday.

Lismore City Council has closed Tuntable Creek Road at Rose Road.

Significant rainfall has made an existing landslip unstable. Council will advise when the road re-opens.

Gungas Road at Black Sheep Crossing is also closed to through traffic, as there is water over the road.

Based on predictions from the BoM, the following areas may be impacted by dangerous floodwaters:

• Low-lying roads, causeways and bridges
• Low-lying farming and rural areas
• Low-lying areas along the riverbanks
• Camping grounds along riverbanks and creeks
• Unsealed roads may be impacted

What you need to do:

• If you have a Home or Business Emergency Plan, follow it. Otherwise, have a conversation and plan for what you will do and take with you if you need to evacuate.
• Consider the consequences of road and bridge closures and water over roads and make alternate arrangements for work, children, and travel.
• Obey all signs about road closures and instructions from emergency services.
• Never drive, walk, ride through, play or swim in floodwater-it is dangerous, toxic, and may void your car insurance. Ifit's flooded, forget it. Fines may apply.
• Avoid storm drains and pipes, ditches, ravines, creeks, and rivers.
• People in areas likely to be impacted by flooding should raise their assets, including waste and chemicalcontainers above expected flood heights.
• Share this information with family, friends, and neighbours and help others prepare where possible.
• People working or camping along the river should monitor river heights and be prepared to relocate to higherground.
• Farmers should consider moving pumps and farm equipment to higher ground.

For emergency assistance during a flood, storm or tsunami, call the NSW SES on 132 500. In a life-threatening emergency, call Triple Zero (000).
