For people in Northern Rivers and parts of Northern Tablelands Forecast Districts.

Issued at 10:37 pm Sunday, 31 December 2023.
Heavy rainfall about the Northern Rivers overnight Sunday and persisting through Monday.

Weather Situation: A high pressure system moving into the Tasman Sea is directing persistent and very humid easterly winds over northeastern parts of New South Wales. Persistent showers and thunderstorms with heavy rainfall are expected to trigger on a coastal trough overnight Sunday and persisting into Monday, with further support from an upper trough sitting to the southwest.

HEAVY RAINFALL which may load to FLASH FLOODING is forecast for the Northern Rivers and parts of the Mid North Coast and Northern Tablelands districts during Sunday night and Monday. Three to six-hourly rainfall totals between 80 and 160 mm are possible, with isolated 24-hourly totals exceeding 250 mm possible.

Heavy falls will be associated with shower and thunderstorm activity, which is likely to be somewhat hit-and-miss in nature across the warning area. These conditions are expected to continue during Monday.

Localised intense rainfall is possible under areas of persistent heavy thunderstorms. Separate severe thunderstorm warnings may be issued to highlight areas of intense falls if they are expected.

A Flood Watch is current for parts of the warning area. Flood warnings may be issued as required. Please refer to

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.
