Updated 4.15pm, Tuesday June 13: The Bureau of Meteorology (BoM) has cancelled its severe weather warning for the northern rivers as the coastal low trough continues to move north into south-east Queensland.
Heavy rainfall has eased about northern parts of the Northern Rivers and the immediate threat of severe weather has passed, but the situation will continue to be monitored and further warnings will be issued if necessary.
But the BoM is continuing to warn people to be careful around floodwaters, creeks, drains, fallen trees and debris.
As always, do not drive through flooded roads or causeways.
Rain has eased considerably in the Brunswick River and Marshalls Creek catchments since 9am this morning.
A minor flood watch remains current for renewed flooding. The situation is being closely monitored and warnings and predictions will be issued if necessary.
Up to 188 millimetres of rainfall has been recorded during the past 72 hours to 4pm Tuesday over the Richmond and Wilsons River valleys. This rain has caused renewed river level rivers on the upstream tributaries of the Wilsons River.
Further rainfall is forecast. The situation is being closely monitored and revised predictions will be issued if necessary.
Marshalls Creek at Billinudgel is expected to peak below minor flood level Tuesday afternoon.
Minor flooding is occurring along the Wilsons River at Lismore.
The Wilsons River at Lismore is likely to reach around 5.80 metres AHD early Wednesday morning, with minor flooding.
Minor flooding is expected along the Richmond River at Coraki and Bungawalbyn.
The Richmond River at Coraki is likely to reach around 4.0 metres Wednesday afternoon, with minor flooding.
The Richmond River at Bungawalbyn is likely to reach around 3.60 metres Wednesday afternoon, with minor flooding
There have been no further updates from the SES as at 4.15pm.
Original report: Hundreds of millimetres of rain have fallen across the north coast over the weekend, and that trend is set to continue during Tuesday, the Bureau of Meteorology (BoM) warns.
The BoM says rainfall totals in excess of 200mm have fallen in the 72 hours to 4am today and predicts to 100-150mm further may fall in parts of the northern rivers over the next two days.
But despite the at times heavy falls, rivers in the region remain either at or below their minor flood levels due to the gaps between rainstorms.
Nevertheless, the SES has issued an early warning of possible flash flooding for the Murwillumbah CBD.
A similar message has been issued to business owners in Byron Bay.
The SES recommends that residents and businesses in flood prone areas prepare now for potential flooding from further heavy rain. Increased river heights and wet catchments may result in short timeframes for business owners to pack up and evacuate.
‘Everyone in a flood prone area needs to be undertaking their preparation now,’ an SES spokesperson said.
Residents are being urged ‘to remain vigilant, monitor rainfalls, stay up to date with current information via the local SES Facebook page and be ready to act.’
NSW DPI reports that rough conditions have required the removal of SMART drumlines at Evans Head, Ballina and Lennox Head today.
Swimmers and surfers are encouraged to use caution.
Up to 60 millimetres of rainfall has been recorded during the past 12 hours to 4:00 am Tuesday over the Richmond and Wilsons River valley, causing renewed river level rivers on the upstream tributaries of the Wilsons River.
An average of 144 millimetres of rainfall has been observed in the past 48 hours to 7am this morning over the Brunswick River Valley, with up to 35 millimetres fallen between 4am and 7am.

Minor flooding is current along the Wilsons River at Lismore.
The Wilsons River at Lismore (AHD) peaked at 4.68 metres early Monday morning. With forecast rain the Wilsons River at Lismore (AHD) is likely to rise again and reach around 5.50 metres Tuesday afternoon with minor flooding.

The SES recommends that business owners take advanced steps to prepare for the potential impact of further heavy rain, which may result in flash flooding with short timeframes for business owners to pack up and evacuate.
