Some fantastic widespread falls throughout the state, with a number of locations on the South Coast receiving in excess of 100mm. A huge rain band is approaching the coast south of Sydney, am expecting another 50mm today at least in many areas.

GFS was onto this early doors, but they eased off the overall rainfall figures. It will all depend on how long the low stays near the coast (forecast to slip away towards NZ later tonight).

Wouldn't be surprised to see a few flood warnings issued.

Ivanhoe has recorded 36mm of rain to 3pm today.
Their daily record for May is 58mm so it's a flukey chance of breaking it!!

Ivanhoe officially received 45mm for the 24hr period, thus missing the record.
Still a mighty fine drop for May!!!

[Karl Lijnders]

impressive falls Wes.

I think Sydney will get 100-150mm in quick time. Certainly will be a wild few hours.

If your in the region, join up and let us know what is happening!!!

[Blackee]

Terrey Hills radar seems to be over-estimating the rainfall mate.
Still good for 50mm IMO, maybe not 100mm.
However, BOM has forecast the heaviest falls this afternoon.

Similar to VIC, NSW is forecast to get another rain event later in the weekend.

System is now scooting away from the coast, taking the heavy rain with it.
Nevertheless, some great falls received.
This is looking like a mere entrée to Sun/Mon

Bit mediocre for the forecast but 34mm in Sydney not too bad. Weather will stabalise rapidly overnight.
