East Coast Australia / More Severe Wet Weather Predicted/ Update 30th March

NASA had created a Climate Spiral showing monthly global temperature anomalies (changes from an average) between the years 1880 and 2021. Whites and blues indicate cooler temperatures, while oranges and reds show warmer temperatures. It can be seen global temperatures have warmed from mainly human activities as time has progressed.
As a result of global warming, climate change has created scenarios where dangerous weather events have become more frequent or severe.
This summer in eastern Australia, a severe weather event resulted in record flooding. This follows the disastrous drought and heat induced bushfires of 2019/20.
However it seems the severe wet weather is not over yet.

The Bureau of Meteorology has urged residents in flood-prone areas to remain vigilant as an estimated 100mm is set to fall along the NSW coast, including Sydney, from late today (Wednesday) in a weather event that could lead to flash flooding.

More than 150mm of rain is predicted over the seven days until next Wednesday from about the Illawarra region (that’s us) to Moreton Island in Queensland.

Rivers and water catchments across the state’s east coast have not had enough time to dry out since the flood emergency at the start of the month, and therefore are at greater flood risk, even with a small amount of rain. The root zone soil map below shows how saturated the east coast is. 

Meanwhile, the wet weather looks set to linger until later this year with trade winds still stronger than average in the western Pacific, delaying the weakening of the weather system.

Update: 30th March

And so the predictions have come to pass, but even worse than envisaged.

The Northern Rivers district only a few weeks ago devasted by floods, is having to cope with more. The town of Lismore is being evacuated again as waters top the levees.

We have no idea how much rain has fallen there as the weather station was destroyed in the last flood.

 But nearby Ballina has recorded 300mm in the last 24 hours following 150mm the day before.

That’s around a total of 1400mm (55 inches) in the last two months.

And it continues to rain the entire east coast from Brisbane to the Victorian border.

We here have had more than our annual rainfall in 3 months ie. +1000mm or 39 inches.

A Trip to Canberra / Piano Hunting

It was time to visit the nation’s capital, Canberra, again after three and a half years, the last two of which were due to covid isolation.
The mission was to ‘test’ a few electronic pianos. The co driver’s current one is old and has begun to play up (excuse the pun) and is non repairable.
She had a number of potential brands/models on her list but due to a severe shortage of instruments in Australia and indeed world wide (again covid related), retailers have had little stock.
But we got word some models on her list had arrived, so off we went in the new car’s first long journey over the mountains.

After only 30 minutes something new appeared. They are building a replacement bridge across the Clyde River at Nelligen! 

Who knew?
Not us.

The car performed well going up and over Clyde Mountain pass.
There were plenty of roadworks on the way as the recent torrential rain had caused some damage. This meant delays so the trip turned into 3 hours all up.

Sadly the affects of the 2019/20 bushfires are still obvious. What was once thick verdant rain forest on the eastern escarpment is now patched with black and grey. Recovery is slow but happening however. Tree ferns were the first to regenerate.

The co driver spent time at Better Music, a very impressive business, discussing and test playing some pianos while I walked to outdoor sports store nearby to pick up some kayak rack accessories.

She appeared 90 minutes later with the news she had ordered a Kawai which will be delivered and installed in a few weeks.

On the recommendation of the sales guy, we headed into suburban Canberra for lunch at Fox and Bow to celebrate. There were a few false turns getting there. Canberra can be a bit of a rabbit warren for outsiders.

We both enjoyed a Casablanca salad and good coffee.
On the way home we stopped at historic Braidwood for a quilt shop visit. 

The business has recently changed hands and the disorganised chaos and clutter of the previous owner has gone which impressed the co driver immensely. As per usual purchases were made.
Then it was an uneventful drive down the mountain and home. 

A long but successful day.

Sydney Harbour Bridge / 90 Years Old Today

Some personal connections to the bridge:

The bridge is held together by six million Australian-made hand-driven rivets supplied by the McPhersons company of Melbourne. My father was with this company his whole Australian working life.
My mother was among the 300,000 crowd at the opening of the bridge in 1932 and said she witnessed Francis de Groot bolting up on a borrowed former racehorse and slashing the ribbon with his sword, declaring the Bridge open.

De Groot was a leading member of the New Guard, a right-wing militia group disenchanted with the Premier Jack Lang’s (a socialist) decision to open the Bridge himself, instead of the Governor who was the Queen’s representative.

Current connection with the bridge: 

We live just a short drive away from the Moruya quarry which was the source of the granite facing for the bridge pylons.

Still beautiful after all these years.

A ‘Rain Bomb’ / Part 2

After flooding the capital of Queensland, Brisbane, the ‘rain bomb ‘ system moved slowly south towards Sydney, while dumping another huge amount of rain on the Northern Rivers district of New South Wales. Some places had their annual rainfall in 24 hours. One weather station recorded nearly 800mm (31inches).
Murwillimbah on the Tweed River was inundated.
The town of Lismore is situated on Wilsons River, a tributary of the Richmond, one of the three Northern Rivers.
It has had flooding before.
But this time it has been devastated. 

See YouTube video below.

https://youtu.be/vfAF60gjnMA

Water rose in the town 2m (6ft ) above the previous record level to 14.5m (47.5ft).
People were trapped in the houses the water rose so quickly and some had to get into their roof space and cut through the roof to await rescue.
The flood waters moved south into the Richmond inundating towns like Woodburn and even Ballina at its mouth.

We were under a severe weather warning here but the system seemed to falter just north of Sydney and then turn inland. We got plenty of rain however, nearly 200mm (8 inches) over 3 days and our creek came up with the lower paddock flooding. But that was short lived as the coastal lake our creek runs into was opened up by the huge surf (5m/16ft waves) and the water quickly drained away. If I can hear the surf at our place, I know it’s big!
But we got continual heavy showers for days after. Our total for this weather event was around 500mm (20 inches)
Everything is very very soggy. 

But thankfully we were spared the disaster those up north endured.

Western Sydney had bad floods as a result of the system with half a million people on evacuation orders. That area is on the flood plain of two major rivers and, despite them being dammed, torrential rain always causes problems. The dams were full this year and they had to release water for safety reasons, causing problems downstream.

We here have now had our annual rainfall in less than 6 months.
This has been the wettest and coolest summer I can remember.

Funnel Web Spider Time

Experts are warning there will be a spike in funnel-web spider sightings across Sydney and environs as wet conditions create perfect conditions for them to thrive.
Male funnel-web spiders leave their burrows in search of a mate and can sometimes end up in homes or gardens.

The wet weather over the past weeks is expected to bring an increase in the number of spiders wandering about.
Their natural habitat is rainforests but private well-vegetated gardens also make a perfect home.
Sydney funnel-webs prefer cool, damp places like the laundry, garage or shoes left on the ground.
People are advised not to not leave washing and clothing on the floor and if shoes/boots are left outside it’s best to give them a tap before "putting your foot in blindly".

The Australian Reptile Park , just north of Sydney, is the sole supplier of the lifesaving antivenom and request anyone (very carefully) catching a spider to bring it to them for ‘milking’.

Since the introduction of the program, there has not been a single death due to a deadly funnel-web.
They advise if you're to get bitten by a funnel-web spider, to stay as calm as possible and apply a pressure immobilisation bandage and get to hospital as quickly as possible.

A ‘Rain Bomb’ / Part 1

On Wednesday 23rd February the Bureau of Meteorology warned that an area of low pressure over the south coast of Queensland was dragging in moisture from the Coral Sea to the north and then lifting it over the coastline.
On Thursday large areas of south-east Queensland were placed under a warning for intense rainfall and thunderstorms that will cause flooding.

On Friday, the area of cooler air in the upper atmosphere drifts into the low pressure trough and starts to deliver record-breaking downpours over Brisbane and its surrounds.
On Saturday torrential rain hovers over the Brisbane region feeding the city’s Wivenhoe Dam which is filling at an incredible rate.
On Sunday Brisbane wakes up to major flooding.

There is a “rain bomb” over the city. Prime inner-city areas precinct are underwater.
There are scenes of devastation in low-lying suburbs, along creeks, and in the river itself where pontoons break free and ferry terminals are littered with smashed boats and debris.

There are up to 15,000 homes flooded in the city, with 1,544 people in evacuation centres in the south-east. Trains are cancelled, bus services limited, the main Bruce Highway is closed at multiple locations and 51,000 people are without power. At least 3,600 homes are flooded in Gympie on the Mary River to the north.

Some 612mm of rain fell on the city between 9am Friday and 6pm Sunday – the highest three-day total in records dating back to 1840.
The previous record was 600.4mm in 1974.
But that’s not the end if it.
As the weather system moves south, and Brisbane starts the clean up, there is devastation in northern NSW as Wilsons River rises two metres above previous flood records, inundating the town of Lismore.
On Tuesday morning evacuation orders are issued for South Ballina.

Winter Wood Delivery

Our normal fire wood supplier had no stock this year.

The fallout from the 19/20 bushfires is still with us causing shortages.

Demand is high as people like us had their stockpiles burnt plus potential sources on the ground from fallen trees and branches were also destroyed.

We did have a small stockpile made up of old partially burnt wooden posts and rails put aside during our post bush fire fence replacement phase but certainly not enough for this winter.

I have always noticed over the years a huge pile of firewood for sale at a local nursery near Milton called Gardenhaven.

Quality looked fair albeit a bit pricier than we are used to but there was little alternative.

Turns out it was at least 25% cheaper than in Sydney!

I ordered 6㎥ on a Saturday morning and it was delivered at lunchtime.

Top marks for service. 

It was dumped in a pile in our backyard within a short wheelbarrowing distance of our woodshed.

There was obviously a lot of stacking to do.

I looked at that as part of a keep fit or rather getting back in shape campaign.

The co driver and I worked on stacking an hour (10 load target) or so a day in the relative cool of the morning.

A few days heavy rain kept us from our target but finally a week after delivery it was all put away.

There was very little useless residue and a small quantity usable kindling in the pile.

And the quality was much better than expected.

Might just be our ‘go to’ supplier next year.
