FLOOD WATCH FOR THE NEW SOUTH WALES COASTAL VALLEYS FROM THE QUEENSLAND BORDER TO TAREE FOR THIS FRIDAY AND SATURDAY
Australian Government Bureau of Meteorology New South Wales
Issued at 11:52 am EST on Wednesday 29 April 2015
Note: This Flood Watch is a "heads up" for possible future flooding along all rivers and creeks within a nominated valley and is NOT a Flood Warning [see note below].
Onshore winds and rain will increase as a trough deepens off the northern NSW coast on Thursday and Friday. Another East Coast Low is expected to form within this trough on Saturday near the QLD border before moving south to be offshore of the Mid North Coast on Sunday. The northern half of the coast (Mid North Coast and Northern Rivers) will receive the heaviest rain with multi-day falls of 150-200mm, locally 350+mm from Wednesday night to Saturday. Friday and Saturday will see the heaviest widespread falls.
At this stage there is a greater than 70% chance of flooding in the following river valleys developing during Friday and Saturday:
1. Tweed River valley - moderate to major flooding
2. Brunswick River valley - moderate to major flooding
3. Richmond and Wilsons River valley - moderate to major flooding
4. Clarence River Valley, including the Orara River - minor to moderate flooding
5. Coffs Harbour - minor to moderate flooding
6. Bellinger and Kalang River valley - moderate to major flooding
7. Nambucca River valley - moderate to major flooding
8. Macleay River valley - minor to moderate flooding
9. Hastings River valley - minor to moderate flooding
10. Camden Haven valley - minor to moderate flooding
11. Manning River Valley, including Gloucester - minor to moderate flooding
There is still the possibility of renewed flooding in the Hunter Valley (including the Paterson and Williams Rivers) on Sunday and Monday. This will be reviewed on Thursday based on the latest information.
This Flood Watch means that people living or working along rivers and creeks 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 over 70% of Flood Watches are followed by flooding within the catchment.
