1mm overnight. 2.5 mm for the event.
Dark clouds and rumbles of thunder on the horizon but that is at the moment where they have been staying for the last few hours.
Hoping for 10-20mm at least just to water the garden.

Should we be worried about that huge blob of rain heading straight for the coast - in particular - north of Brissy towards the Sunshine Coast? Shear is quite strong at 500hPa and steering it in that direction.

-97mm from 9am Sat-Sun
-19mm at the beginning (9am Sat, 10/06/17)

Event total as at 9am: 252mm (still raining steadily!)

I'm about halfway between Murwillumbah and the coastline.

If it reaches the land and maintains that intensity (which looks even heavier than here), then yes.

335mm at Alstonville now for event , Big wow factor is nearby Rous Mill , still on the plateau's southern fringe , 550mm over wknd! not what they wanted as the area is under macadamia nut trees , and a lot of this years crop just washed down the gullys and creeks.

I think some of the high reflectivities from that mass is due to the bright-banding phenomenon (water-coated ice/snowflakes reflecting back a lot more radar energy than normal raindrops).

The freezing level is only around 9000ft at the moment and a lot of the precip above that would be a mix of supercooled droplets/ water coated ice/snowflakes.

Brightbanding is commonly seen on weather radars in situations like these and make precip reaching the ground look heavier than it really is.

There's still be a fair bit of rain under it though.

17mm total so far for this event since this morning. Not bad considering the range usually sucks the life out rain events heading towards us from the east.

Thanks for that explanation Ken. That makes sense. If only we had a 3000m mountain range rising off the coast it would make for great skiing conditions. grin

Rain gauge sitting at 45.0 mm for the event at Salisbury, so just 4.8mm falling since 6.00 a.m today...watching the radar the heavier falls looked to be South of here this morning and now North of here this arvo.

At what altitude does the radar beam penetrate the precipitation?

Would 3000m be high enough at that latitude?

The rain pretty much cleared here during yesterday evening, with very little falling afterwards. 36.0mm in the 24hrs to 9am.
Today was a mostly sunny day until cloud moved in around 4pm. There have been a few showers pass over since then, but they have been quite fast-moving, so only 2.2mm has fallen.

Minor flood warnings current for the Orara and Richmond-Wilsons Rivers. Terania Creek (near Nimbin / the Nightcap Ranges) was the wettest place in the 24hrs to 9am with 101mm there.
