Peter Hannam: A slew of January rainfall records are likely to have been broken as the remnants of ex-tropical cyclone Oswald heads south along the NSW coast.
The weather bureau is still assessing the quality of the data collected for the 24 hours to 9am but initial numbers point to Crystal Creek on the mid-north coast’s Bellinger River as recording the highest rainfall total of 288 millimetres.
Sydney’s Observatory Hill recorded 95mm of rain for the period, the highest level since last March’s severe rainstorms.
In the Sydney region, the north shore’s French’s Forest and Castle Cove both saw 161mm land in their rain gauges in the 24 hours to 9am today.
The Upper Rous River probably saw the state’s heaviest falls from the storm, with 944mm landing in the border zone site near Queensland over the past three days.
“It’s not far short of a metre of rain,” Aaron Coutts-Smith, NSW manager of climate services at the weather bureau.
“When you think of those volumes, it’s no wonder there’s been flooding.”
That tally, though, fell short of the state’s all-time record over three days, of 1090mm recorded in December 1975 at Bowraville, Dr Coutts-Smith said.
Megan Levy: Some more details on the evacuation order issued in Grafton.
More than 1500 residents near Grafton have been ordered to evacuate this morning as authorities prepare for the Clarence River to peak at midday.
The Clarence River is expected to peak at 8.1 metres, but the SES says it could be higher.
‘‘There is a chance of that. What we’re dealing with here is a flood of record. There has never been a flood of this heighr in recorded history in Grafton,'' Caroline Ortel, Region Controller at the NSW State Emergency Service, said at a press conference a short time ago.
The State Emergency Service issued a flood evacuation order for Dovedale and North Meadow at 8.30am, telling residents to leave their homes immediately.
‘‘Do not delay your evacuation,’’ the SES said in a statement.
‘‘Roads will be congested or closed. You could become trapped and need rescue. Remaining in flooded areas is dangerous and may place your life at risk.’’
Authorities originally expected the Clarence River in Grafton to peak at 7.9 metres at about 9am on Tuesday.
The Bureau of Meteorology has issued a major flood warning for the Clarence Valley, and a moderate flood warning for the Orara River.
Georgia Waters: Our list of road closures in Sydney and around New South Wales has been updated again. Please see our 7.44am post.
Georgia Waters: Thousands of residents in low-lying areas of Grafton in northern NSW have been ordered to evacuate.

On page one of today's Herald, reporters Jacob Saulwick, Peter Hannam and Gemma Khaicy write that reports prepared for the O'Farrell government say large parts of far-western Sydney remain vulnerable to the types of flooding that occurred in Brisbane two years ago.
The reports say large-scale casualties and billions of dollars in property damage would be expected unless the Warragamba Dam wall is raised 23 metres to reduce the chance of flooding in the Hawkesbury Nepean Valley, or roads are improved to let people escape from a flood.
The dire warning is not predicted to eventuate from the latest downpour.
One of the reports prepared for the government, by the consultants Molino Stewart, outlines the devastation that would occur if there was a repeat of the largest recorded flood, in 1867.
It would put at risk more than 26,000 people in places such as Emu Plains, Penrith and Windsor, and cause thousands more to evacuate. An 1867-level flood would hit about 7000 homes, cause significant structural damage to 1200, flood more than 1600 businesses, and cause more than $3 billion in damage.
Adrian Lowe: We've heard from Qantas on the status of east coast flights on Tuesday.
A spokesman said services were expected to return to normal, but passengers would need to check online during the day.
"We are working to get customers who were on cancelled flights yesterday to their destination," he said.
Both Qantas and Jetstar were adding extra services, he said, and some larger aircraft may be put on for Qantas flights.
The spokesman added Qantas had offered support to the Queensland government to help with the recovery effort, "particularly in and out of regional communities like Bundaberg''.
Information on Virgin Australia flights can be found in our 8.52am post.
Peter Hannam: As of 7am AEDT on Tuesday, insurers have received some 6100 claims for losses in Queensland from the floods, the Insurance Council of Australia says.
Those claims involve insured losses estimated at $72 million, with the tally now "rising rapidly", according to the ICA's head of corporate affairs, Campbell Fuller.
So far, insurers are yet to receive many claims relating to losses in NSW from the storm.
Adrian Lowe: We are still seeking information on flights in and out of Sydney from Qantas and Jetstar, but we have this information from Virgin Australia.
Several Virgin flights in and out of NSW and Queensland have been cancelled, including between Sydney and Melbourne, Melbourne and Brisbane, Sydney and Brisbane and Sydney and Canberra.
Virgin Australia has advised passengers that if their flight has been cancelled, they should have received an SMS notification.
A full list of cancellations can be found here.

Reporter Megan Levy has written a wrap of what's happened so far with the weather in Sydney and the forecast - read it here.
Georgia Waters: We have just updated our list of roads in Sydney and in NSW that are closed - see our 7.44am post.
Georgia Waters: The city of Bundaberg, about 385km north of Brisbane, has been the area the worst hit by disaster, and is experiencing its worst flood on record. More than 2000 homes are underwater and the force of the floodwaters in the city is so strong it's been feared whole houses could be swept away.
On Monday night, 1500 stranded residents were airlifted to safety and placed at one of nine evacuation centres.
Bundaberg's Burnett River is expected to peak at up to 10 metres on Tuesday.
In Burnett Heads, near Bundaberg, an 81-year-old man died after falling off his yacht as he tried to secure it against wild weather on Sunday.
These photos show the extent of the crisis.

Georgia Waters: Flying out of or in to Sydney Airport this morning? Long delays are again expected, with passengers this morning complaining on Twitter of cancelled flights and huge lines at check-in.
Sydney Airport tweeted about an hour ago it was ''back to normal'' at the airport however passengers flying to storm-affected areas should check with their airline before coming to the airport.
While the flooding in Queensland this week has been nothing like the disaster of January 2011, in which 35 people died, these photos show just how serious it has been in some areas.
In Brisbane on Tuesday, the Brisbane River is forecast to peak at 2.6 metres - almost half the 2011 peak of 4.46 metres - at 11am AEST (12pm AEDT). A second flood peak is likely at noon on Wednesday.

Megan Levy: While Sydney was saturated with rainfall of between 80 and 150mm overnight, the heaviest falls had passed by 5am, according to Weatherzone meteorologist Brett Dutschke.
The rain is expected to ease on Tuesday morning and clear by the afternoon, with Sydney expected to reach a maximum of 27 degrees. The rain has also eased in the north of the state, where temperatures are expected to reach the low 30s on Tuesday.
However Mr Dutschke said there was the chance of showers and thunderstorms in coming days.
‘‘While this rain is becoming much lighter and clearing, there is still a moderate amount of instability and it’s enough to cause afternoon showers to develop for the next few days and even a few storms, in eastern parts of NSW and Queensland,’’ he said.
Brisbane, meanwhile, is forecast for a break in the rain, with a fine and partly cloudy day with a maximum of 33 degrees expected.

The latest victim of the crisis was a three-year-old boy who was watching floodwaters at Gordon Park, in Brisbane's north, with his family yesterday morning when a large gum tree fell and trapped them.
His pregnant 34-year-old mother was also severely hurt but his father and brother weren't badly injured. The little boy was taken to hospital but had sustained critical head injuries and died last night.
