Locally, the rain event is expected to be more significant in NE NSW with totals of the order of 150 to 200mm range.
And just to top things off – severe storms on the mid-north coast with a severe warning in play.
See : 128km Radar Loop for Newcastle, 03:00 22/11/2011 to 14:00 23/11/2011 UTC
Latest model output keep the heavier rain in NSW and inland southern QLD. Bit of instability today too so might see a storm amongst the development in the Northerb Rivers.
The flood watch has been extended and suprised to see it sayd moderate to major flooding in NE NSW – it will take a lot of rain for that to eventuate

Hi Michael,
And there have been substantial falls in south east Queensland as well in the past 24 hours.
Here we have had just over 50mm of rain 27.6mm +19mm this morning.

Some impressive rainfall totals across the NSW Northwest Slopes with major flooding expecting into Moree later. Not often you see such high totals in those parts of the state – though it is more likely in a La Nina year. Gravesend east of Moree had 190mm to 9am 26th Nov

Up to 300 millimetres of rain has fallen since Wednesday morning in the lower Gwydir Valley. Intense rain of 40 to 50 millimetres in less than 6 hours has been recorded at several locations this morning.
This rain will worsen the flood situation with respect to predicted heights and result in earlier timing of major flood levels in the lower valley.
Predicted River Heights/Flows:
Peak predictions will be made when upstream peaks are observed.
Gravesend
– reach 14.5 metres around 9pm Saturday evening with major flooding
Pallamallawa
-reach 10.4 metres around 3am Sunday morning with major flooding
Yarraman Bridge
– reach 7.4 metres Sunday morning with major flooding
Moree (Meehi River)
– reach 9.5 metres Sunday night with major flooding
Michael,
Seems like the North West Slopes and Plains copped the anticipated heavy rains and experiencing major flooding. Not often have I heard of Moree and Wee Waa in recent years in major flood modes.
Does anyone know if the peak reaches in Moree has exceeded any significant records?

Media reports last night incidate the floods are receding and had peaked. Unfortunately, aprt from the damage it has caused, it caused one fatality.

A mid-north coast webcam (Mid Coast water) just north of Forster captured those storms you linked the radar to Jimmy. Shows a semi-interesting feature
