Loc: South West Rocks, NSW
Very dry August along the NENSW coast. A handful of locations on the Northern Rivers and the northern Mid North Coast recording no rain at all, including Bellbrook, Bentley, Cooks Ck, Grafton South, Kunghur, Lillian Rock, Millbank, Minnie Water and Tuncester.
A reasonable number recording less than 1mm, particularly about the Richmond, Clarence and Macleay valleys. Yamba (0.6mm) and New Italy (0.9mm) had their driest August since 1913. The BOM weather stations at Coffs Harbour, Grafton Research, and Casino recording just 0.2mm for the month.
Parts of the Coffs-Dorrigo-Grafton area is shaded with lowest on record rainfall for August on the Decile map.

Yep its dry as buggery here and just about everywhere else in the region by the sounds.
Last rain here was 30 days ago
Last fall over 5mm was 49 days ago
Last fall over 20mm was 125 days ago from debbie

Seems like we have been stuck in a pattern of dry years since 2013 with a few random, widely scattered rain events to break the monotony and provide most of the rainfall over that period. Maybe this summer we'll see some heavy rain events minus the long rainless periods like years past...
It could be worse I 'spose, we could all be living in Townsville!!

Drove out along Samford Rd today to a property about 8klms the other side of Dayboro for a Fathers Day picnic...several times along the way I made mention to my wife how dry and brown it was everywhere. We certainly need a good drink in many areas that's for sure, starting with my backyard...plenty of dirt patches starting to appear now where the grass used to be.

it's certainly possible, in fact it's happened before and it will probably happen again.

https://en.wikipedia.org/wiki/1893_Brisbane_flood

For the first flood, Crohamhurst recorded an all-time Australian record of 914.4 mm of rain in a 24-hour period.[4] The water surge was recorded on the Port Office gauge (now the City gauge) as being 8.35 metres (27 feet, 5 inches) above the low tide level. The February 1893 floods were the second and third highest water levels ever recorded at the City gauge, the highest being the January 1841 flood at 8.43 metres (27 feet, 8 inches).[5] There was however some oral aboriginal history suggesting a flood level of nearly 12 m prior to the first European settlement.

Thunderstorms this evening brought 91km/h wind gusts at Tamworth and 76km/h wind gusts at Armidale (a few photos from that general area here https://www.facebook.com/tamworthregionweather/videos/2034788830089909/). As forecast, the storms quickly weakened once they moved down the coastal side of the ranges, with no rain occurring on the coastal plain.
The dry weather looks likely to continue here for another week at least.
0.2mm has fallen over the past 49 days at Coffs Harbour. 0.4mm over the same period at Dorrigo.

Nice shots in that fb post Seabreeze.

Still on track for daytime temps soaring to 30C or above away from the coastline... once again, into the hottest 10% of max temps for the month.

Not a single model going for any rain for much of SE QLD within the next several days either and nothing major appearing in the 7-14 day period yet.

But then again, what else is new for here *cue very broken record*

This weather is reminding me of 1991/92 (I think it was around that time)were we had warm to hot days but the mins'. were still around 10C for September. Nice sleeping weather but towards Nov/Dec the storms lasted for hours,constant rumbles and flashes. One storm hit at 20:30 aprox and slid out to sea around 3:30am. The thunder cracks were massive with sheet lightning and hundreds of CG's and sky crawlers. I would assume if I had the data back then to check, the humidity must have been low causing a lot of static. There was also a massive hailstorm with strong winds that caused damage on the Northside as well. I just did not keep records back then beside my job diary. My 1st computer was in 1993 being a 486 that ran DOS wand Windows, everything was command prompt in Dos. to enter windows it was C:\WINDOWS, had no memory and I didn't get the internet until 1994.

Yes, I remember that time as well, a ferociously dry July to September, severe frosts, howling westerlies. But it gradually improved and there was even a major rain event in December. Hope it changes earlier this year.

Obviously there's a squillion variables there, 1,000mm in 72 hours is well within reason for the coastal areas but it depends how far inland that goes. The Somerset catchment is 1,300km2 but Brisbane above Wivenhoe is over 5,600km2. If you've never been out past Linville it's hard to comprehend just how big the area out there is.

Maleny had 750mm in 81hrs in 2011 on incredibly saturated ground and there was no real risk of Wivenhoe or Somerset failing. If we had a cyclone that caused 1,000mm in 72hrs at Maleny and lesser amounts inland with the current dry conditions i think the dams would be fine.

If on the other hand, there was a uniform 1,000mm in 48hrs across the whole 7,000km2 above Wivenhoe with the saturation we had in 2011, that would be a bad situation. That would be nearly 7 million megalitres coming out of the sky, the flood compartment of Wivenhoe is only 1.46 million. That is a very hypothetical scenario though, in reality the rainfall drops off very quickly the further west you go.

Harvey rainfall:



Google tells me Houston to San Antonio is 320km. I think that would make the blue area of above 40inch (1000mm) roughly equivelant to Brisbane to Double Island Pt, and along the range. My estimate of a Wivenhoe sized blob to NE of Houston would be extending to just barely the edge of the 20 inch area, so maybe 600-700mm average. I think 2011 was around 300-400mm average for the catchment.

Just had a brief shower here. Drops very large, widely spaced and cold. Not even worth bringing in the washing for but at least its something.

Sky to the south from Buderim has looked impressively unstable, but with quite high bases and low tops.

I looked at the clouds forming to the north after lunch, they looked impressive & getting higher so they seems to have delivered the goods to a few. Nice.

Wow that Hurricane Harvey rain fall map map is insane. Could you imagine the the SE corner of QLD copping that .300 mm does major problems let alone a 1016mm or 40 inches.
