Records are tumbling as rain continues to lash NSW — and it's not over yet.
Key points:
Nelson Bay has copped its biggest downfall since records began in 1889
More than 200mm of rain has fallen in Parramatta in the past three days
The rain is forecast to continue until at least Wednesday
Nelson Bay on the NSW Mid-North Coast recorded 458 millimetres of rain in the three days up to 9:00am on Sunday morning, the highest ever three-day total since records began at that location in 1889.
Friday's total of 202mm was the seventh-highest daily fall since records began.
NSW Premier Gladys Berejiklian yesterday said the Mid-North Coast was experiencing a "one-in-100-year event" and the situation there was being watched very closely.
Felicity Gamble, a climatologist with the Bureau of Meteorology (BOM), said the rain event was notable for how widespread it was.
"Normally with an east coast low, it is one location that gets really hammered and others not so much," she said.
The BOM has issued severe weather warnings for all parts of the NSW coast from Illawarra through to the northern rivers and flood warnings for more than 20 rivers.
In other areas though, the rainfall has not topped the drought-breaking rains that fell on February 10 and 11 last year, at least not yet.
More than 200mm of rain has fallen in Parramatta in the past three days.
Ms Berejiklian said the rainfall coming this week was "beyond anyone's expectations" and up to 4,000 people around the Hawkesbury Valley should be on standby to evacuate.
The NSW State Emergency Service (SES) yesterday issued several flood evacuation orders for locations in Sydney’s west as heavy rain drenched the state.
Ms Berejiklian said 16 local government areas, primarily in the north of the state, had been declared a national disaster so far.
Residents in flood-affected areas of NSW have been told to prepare to work from home and keep children out of school this week as the state grapples with the severe weather crisis.
"Going to work, even though you hope it may not be affected, your work premises may be affected in some areas, so once again know that if you do need to go to work make arrangements to work from home," SES Commissioner Carlene York said.
It is not only the NSW coast that is sodden.
The town of Nyngan in central NSW normally averages 43mm for the month of March.
Dr Gamble said Nyngan was forecast to get four times its March average over the next few days.
The rain is forecast to continue until at least Wednesday.
