Heavy rainfall today and tomorrow could lead to flash flooding, the Bureau of Meteorology reported.

Six-hourly rainfall totals between 80-140 mm are possible, reaching up to 180 mm over coastal areas and ranges.

Locally intense rainfall leading to dangerous flash flooding with thunderstorms with six-hourly rainfall totals in excess of 180 mm is possible according to BOM.

Heavy rainfall increases the potential for landslides and debris across roads.

A Flood Watch is current for parts of northeast New South Wales.

Locations which may be affected include Tweed Heads, Murwillumbah, Byron Bay, Lismore, Yamba, Grafton, Coffs Harbour and Dorrigo.

The State Emergency Service advises that people should:
* Don’t drive, ride or walk through flood water.
* Keep clear of creeks and storm drains.
* If you are trapped by flash flooding, seek refuge in the highest available place and ring 000 if you need rescue.
* Be aware that run-off from rainfall in fire affected areas may behave differently and be more rapid. It may also contain debris such as ash, soil, trees and rocks.
* After bushfires, heavy rain and the loss of foliage can make the ground soft and heavy, leading to a greater chance of landslides.
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
* For emergency help in floods and storms, ring your local SES Unit on 132 500.
