Sydney Hail Storm: Just how hailproof are those solar panels?

Here’s a problem coal fired plants don’t need to worry about.

Sydney’s ‘catastrophic’ hailstorm happened on Thursday, the damage bill said to top $125 million. How much of that damage is to rooftop Solar PV? The last massive hail storm in Sydney was in 1999 — but there were hardly any solar panels then.

From SBS News

There are wild scenes and images everywhere.

Worst Sydney hailstorm in 20 years declared catastrophic

Jessica Cortis and Sascha O’Sullivan, The Australian

At least 50,000 homes remain without power in northern Sydney and more than 1000 calls for help are waiting to be responded to by State Emergency Services after Sydney and the NSW central coast were yesterday rocked by the worst hailstorms in almost 20 years.

Before anyone yells “Climate Change”, Reader, Pat, found stories about hail the size of Eggs in Sydney in November 1929. Hail the size of Tennis Balls fell on Reids Creek near Brisbane in 1934 and hail the size of Tea Cups fell on Brookville in 1902. Paddington had “ice inches deep” on Nov 1, 1931. There are scores more Hail-the-size-of… Maybe building 2 million solar panels on a continent with [...]

Hungry children wander among ruins, 30,000 people homeless in Florida after Cat 4 Hurricane (in 1926)

This Week In 1926

Hurricanes aren’t what they used to be.

Tony Heller at RealClimateScience found a photo of what happened when “an actual category four hurricane hit Miami” — as opposed to an almost Cat 6 that became an almost Cat-Nothing.

What Category Four destruction can look like.

At one point Florence was “Becoming The Strongest Storm to Ever Make Landfall North of Florida” and the “costliest ever to hit The US.”

Soon children won’t know what real storms are.

Hundreds of Hungry Children walk amid City Ruins

Imagine if this happened in 2018. The outrage, the scandal. Impeach Trump Now.

On the other side of the world on Sept 20th 1926, The Melbourne Herald reported:

Thankfully we have and do things better now.

The people of Miami didn’t have satellites or TV or helicopters or mobile phones, or perhaps any phones.

Apocalypse 1926

“Hundreds of children separated from their families and hungry, their health endangered by the scarcity of water and the lack of sanitary facilities, are wandering among the ruins of Miami City today.

Worst Storm Ever: Over 8,000 people killed in UK in extreme storm that lasted nine days (in 1703)

Cropped from The Great Storm by Goodwin Sands, 1703

While we soak in storm footage this week, imagine this storm!

Back when CO2 levels were ideal, the UK was hit by a monster nine-day storm: at least 8,000 dead, maybe as many as 15,000 people. Some 2,000 chimney stacks were blown down and 4,000 oak trees were lost in the New Forest alone. About 400 windmills were destroyed, with “the wind driving their wooden gears so fast that some burst into flames”. The worst toll was probably on ships — with some 6,000 sailors thought to be lost. As many as 700 ships were heaped together in the Pool of London, one ship was found 15 miles (24 km) inland. A ship torn from its moorings in the Helford River in Cornwall was blown for 200 miles (320 km) before grounding eight hours later on the Isle of Wight.

Back then, people blamed the “crying sins of the nation” and saw it as punishment by God. The government declared 19 January 1704 a day of fasting, saying that it “loudly calls for the deepest and most solemn humiliation of our people”. Apparently, it remained a topic of preachy [...]

Wild Winter Storm Riley hits NE USA, nine deaths, nearly 2 million without power

At least nine dead in the North East of the US after a savage storm dubbed “Riley”. Nearly 2 million people are without power. Airlines canceled more than 3,000 flights.

Friday afternoon’s high tide in Boston was the third-highest observed tide on record, according to the National Weather Service.

March Brings the Most Variety of Extreme Weather in the U.S.

Jon Erdman argues that March in the US is notorious for storms due to jet streams and a mix of warmer humid air paired with cold winter air. His impressive list of previous March extreme weather is a good antidote to the “Climate Change” claims coming in 3, 2, 1 ….

The deadliest March snowstorm was the infamous Blizzard of 1888, which dumped 40 to 60 inches of snow in New York, Connecticut and New Jersey, wind-whipped into drifts which topped some homes. Four hundred were killed in the storm and its cold aftermath.

Here are a sampling of other notable March snowstorms:

Late March 1987: Three-day blizzard produced gusts to 78 mph at Dodge City, Kansas and Altus, Oklahoma. Pampa, Texas, picked up 20 [...]

Bombcyclone — “a bad storm with good branding”

” The Bomb Cyclone isn’t a winter hurricane — just a bad storm with good branding” — Vox

A “Bombcyclone” off the East Coast of the USA is verging on, or has broken a record for the fastest drops in pressure. It’s now at 965mb. It’s not a bomb, nor a cyclone, just a common winter storm. Though this one is a bad one which has already dumped snow on Florida- “most snow in three decades”. The hastag #BombCyclone is exploding.

Also known as a Blizzard, the National Weather Service forecasting winds as high as 70 miles per hour (113 km per hour), and more than 3,300 flights have been cancelled. — Reuters

BombCyclone, NE USA, Jan 4th.

Record breaking?

Rarely do you get to see such perfection w/ the structure of a winter storm. Running out of adjectives for this one. Our blizzard has dropped 54 mb’s in 24 hours, making it not only a “meteorological bomb,” but one of the fastest stengthening winter storms in modern history. — @WeatherOptics

Roy Spencer explains the Bomb term:

The term “bomb” was coined by meteorologist Fred Sanders in 1980 to refer to a non-tropical low [...]

Massive, unprecedented, 10 out of 10, life threatening storm hits, drops 2 inches on Melbourne

It was all yellow: A warning was in place for the whole of Victoria.

Massive flooding forecast across “whole state”:

The Bureau of Meteorology has warned an “unprecedented” amount of rain is expected to fall in Victoria over a three-day period.

Asked to rate the storms out of 10, senior forecaster Mr Williams said: “I’ll take the punt and say it’s a 10 for Victoria.”

He said the most recent rain in a short period of time in Melbourne was 100-200 millimetres (in 2005 and 2011) and on both occasions: ”it paralysed transport routes in the city.”

Get out your sandbags!

Events were cancelled, and the Premier of Victoria told people not to “have a big night on the town” in preparation.

The city was told to bunker down for an “absolutely massive” rainfall event over the weekend …

“Half the inhabitants of Melbourne have never ever seen anything like this,” the Bureau of Meteorology’s senior forecaster Scott Williams said on Thursday.

“It is an event that poses a threat to life.”

Not so much a flood of rain, but there was a flood of text messages:
