A coastal trough along central parts of the coast, cradled between two strong high pressure systems, is bringing widespread rainfall to the New South Wales coast.
Intense bursts of rain, especially associated with thunderstorm activity, are expected about Newcastle and large areas of the Hunter and Mid North Coast during Wednesday, March 21 and Thursday, March 22. This may lead to dangerous conditions in these areas.
Heavy rain which may lead to flash flooding is expected over Newcastle, the Lower Hunter and parts of the Mid North Coast, particularly associated with thunderstorm activity.
Very heavy rainfall, with rainfall rates exceeding 70mm in one hour, are also possible with thunderstorms in these areas.
Up to 100mm to 200mm of rain is expected over the warning area during Wednesday. Similar amounts are expected on Thursday. Some locations are likely to receive more than 200mm in a 24 hour period.
Surf and swell conditions are expected to be hazardous for coastal activities such as rock fishing, boating, and swimming.
NSW Police Force, Marine Area Command advise that:
- People should consider staying out of the water and avoid walking near surf-exposed areas.
- Rock fishers should avoid coastal rock platforms exposed to the ocean and seek a safe location that is sheltered from the surf.
- Boaters planning to cross shallow water and ocean bars should consider changing or delaying their voyage.
- Boaters already on the water should carry the appropriate safety equipment and wear a lifejacket.
- Boaters should remember to log on with their local Marine Rescue radio base, via VHF Radio or the Marine Rescue APP, and consider their safety management plan.
In the event of severe weather activity, 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.
* For emergency help in floods and storms, ring your local SES Unit on 132 500.
