RAIN has eased in the Tweed Valley overnight after more than 500mm fell on the region in three days, flooding most low-lying areas and inundating houses and businesses.
The Tweed River level is falling at both Chinderah and Murwillumbah, however, forecasters predict the reprieve could be short with more rain on the way this afternoon and this weekend.
The river remains on a minor flood warning with evacuation orders still in place for about 3200 people in Chinderah, Fingal Head, South Murwillumbah, Condong and Tumbulgum.
The next river peak will see a minor flood level of 1.3 metres in Chinderah at noon.
Clarrie Hall Dam near Murwillumbah has been reduced from a White Alert to a Protection Alert status meaning the water is now only 1m over the spillway.
Tweed Valley Way at Tumbulgum remains closed in both directions, however, Kennedy Dr has re-opened, with water still on the road northbound and motorists urged to take extra care.
NSW State Emergency Service Commissioner Murray Kear has urged people to heed the safety warnings of emergency services, despite the sunshine.
"It is extremely dangerous to enter a flood, that's why we always tell people to never drive, ride of walk through floodwater," Commissioner Kear said.
"I would urge people to avoid travelling to these flood affected areas and if you are travelling over the Australia Day holiday take care on the roads, particularly if you are driving in heavy rain.
"Pull over to the side of the road, clear of any low-lying areas and put your hazard lights on."
The SES has received 500 calls for assistance since the rain began early this week with the majority from the Tweed area.
For emergency assistance call the SES on telephone number 132 500.
For life threatening emergencies, call 000 immediately.
