Simulated warning information. This is not an actual event



Issued at 9am EST on Saturday morning

Note: This Flood Watch is a “heads up” for possible future flooding along rivers and creeks within a nominated valley and is NOT a Flood Warning [see note below]

Tropical Cyclone Jonica has developed off the south east Queensland coast between North Stradbroke Island and Tweed Heads during Sunday morning. This cyclone is expected to produce rainfall totals between 300 to 400 millimetres with isolated heavier falls starting from Saturday night. This rain will cause widespread local and main river flooding across these valleys.

Strong winds combined with king tides are also expected to produce storm surges that will worsen the flooding in the lower tidal reaches of the coastal rivers in these valleys.

There is a higher than 75 per cent chance that the combined effect of heavy rainfall and storm surge will cause flooding in the following valleys from Saturday afternoon onwards:

  1. Tweed Valley – major flooding
  2. Brunswick Valley – major flooding
  3. Richmond and Wilsons Valley – major flooding
  4. Clarence Valley – major flooding
  5. Coffs Harbour and Wooli – major flooding
  6. Bellinger Valley – major flooding
  7. Nambucca Valley – major flooding
  8. Macleay Valley – moderate to major flooding
  9. Hastings Valley – moderate to major flooding

A Cyclone Warning is current for coastal areas from Double Island Point in Queensland to Yamba in New South Wales.
This Flood Watch means that people living or working along rivers and streams must monitor the latest weather forecasts and warnings and be ready to move to higher ground should flooding develop. Flood Warnings will be issued if Minor Flood Level is expected to be exceeded at key sites along the main rivers for which the Bureau of Meteorology provides a flood warning service. Across NSW, about 75 per cent of Flood Watches are followed by flooding.
For emergency assistance call the SES on telephone number 132 500.

For life threatening emergencies, call 000 immediately.
