Hurricane Hilary Unprecedented? The BBC Would Like You To Think So

August 21, 2023

By Paul Homewood

There are huge amounts of misinformation in this BBC report:

The BBC want you to think this is all record breaking and unprecedented. It is not.

Hilary is a very similar event to the 1939 tropical storm, El Cordonazo,which followed a similar path and dumped similar amounts of rain.

 

Indeed that was one of four tropical storms to hit Southern California in 1939, although the others did not make landfall.

So much for the silly little theory from Ms Treseder, our ecology expert. Maybe the BBC should get advice from proper hurricane experts in future, who would tell them that these storms are rare, but sometimes happen.

The claims about record rainfall are bogus as well. The BBC focus heavily on “record rainfall” in Palm Springs, but even that is a fake claim. They say that 3.18” fell on Sunday, but that was less than the 3.22” recorded in 1926:

In any event, one cherry picked station does not prove anything at all, The BBC also claim that this was the wettest August day on record:

image

This, of course, is utterly dishonest, as it was nowhere being a record in Los Angeles, or California as a whole, merely a record for August at most.

In Los Angeles, for instance, daily rainfall of 2” is nothing unusual at all:

As for California’s wettest day, this is an outright fraud .Hilary dumped 11” or so up in the mountains, but at lower levels it was around 2 or 3”  at most, as the BBC map indicates:

But the 1939 storm was much more devastating, with 5” in Los Angeles:

And the devastation from Kathleen in 1976 was even greater:

https://en.wikipedia.org/wiki/Hurricane_Kathleen

Rainfall from Hilary has not reached anything like the 375mm recorded in 1976.

So once again we find that the BBC can get away with playing fast and loose with the facts, just so that it can promote its political agenda.

        When the BBC says something is “controversial”, you can be sure the BBC hates it. For example, wind farms and solar farms are never described as controversial, whereas fracking is always described as controversial.

    I’ve been to California many times but rarely in the summer. The first thing I noticed about the roads is that they have pronounced gullies on the sides of their roads and traversing some of their roads is often like going over a huge speed hump. They are built that way for a very good reason because when they get heavy rain it can come quickly and can be tropical. I mean super heavy. The roads can be awash in no time flat and that when they need to get rid of the water quickly, hence the gullies and the storm drains which are built like canals. Our road drainage would be quickly overwhelmed. I’ll leave the records and data to others but it is clear that tropical storms are not new in California.

        Don’t forget the authority figure title. The BBC treat the public as morons who all must therefore be impressed by the title “professor” or “expert” and by default accept the persons title to mean whatever they say carries weight and beyond reproach. Notice the BBC never ever inform of their field of knowledge. This is deliberate.
        This is pure theatre a la BBC straight out of the Kremlin playbook. Just like their Climate and Science Reporter Georgina Rannard who’s education is in Modern History, who informed us all that climate change causes global warming, I kid you not!

        The cynical and manipulative attitude of the BBC towards the public for political purposes has no bounds.

    On 24 Sep 1939, Indio Fire Station (about 18 miles SSE of Palm Springs) received 6.45″ from that 1939 “Long Beach Tropical Storm.”

    “Rains washed away a 150-foot (46 m) section of the Southern Pacific Railroad near Indio, and a stretch of the Santa Fe main line near Needles. Crop damage in the Coachella Valley reached 75%.” –Wikipeedya.

    ‘Climate change is in large parts responsible for this storm’

    Wut? How is that? An absurd, even juvenile, assertion.

    ‘says prof Kathleen Treseder, from the University of California, Irvine’s Ecology and Evolutionary Biology department.’

    Oh, she’s a professional.

    ‘It increases the frequency and intensity of the El Niño weather phenomenon’

    [citation needed]

    Even if true, which it’s clearly not, that does not explain this event. Something becoming (allegedly) more frequent is NOT A CAUSE.

    ‘Which leads to warmer waters in the Pacific Ocean and ultimately generates suitable conditions for these storms.’

    Conditions are suitable EVERY GD YEAR.

    “This is a 100 year storm and we’re getting a lot of 100 year events here,” Treseder says”

    Fact free assertion.

    ‘adding that more events of this scope are to be expected in coming years’

    Gross speculation. Evidence free gross speculation. She states it as proven fact. The future is known, she tells us.

    ‘”Whenever we have an extreme event like this now I tell myself this is not gonna be a one-off, likely we are gonna have more and it may even be worse,” she says.’

    Tell yourself anything you want, you silly rabbit.

    This hurricane formed in the eastern Pacific. Happens every year. Several times a year (remember Dora?). They usually head west, toward Hawaii. This time, low pressure off shore, and high pressure in the Great Plains, formed a nip which pulled the storm north, instead of the usual west.

    ‘Climate change,’ whatever the hell that means, did not create a high pressure to the east and a low pressure to the west. Her assertions are childish. Unprofessional.

      YouGov poll shows that the BBC is not as trusted as it (probably) imagines:

      Very Trustworthy 14%

      Trustworthy 30%

      Neither Trustworthy Nor Untrustworthy 24%

      Do Not Know 10%

      Untrustworthy 12%

      Very Untrustworthy 10%

      I suspect that the BBC lost the respect of a significant minority of Right-wingers during the Covid-19 affair.

      I also suspect that the 30% who merely think it “Trustworthy” are mainly Left-wingers, who approve the BBC when it is confirming their prejudices but revert to regarding it as “Establishment” when it shows some impartiality. In other words, if the BBC did ever stop banging on about Climate these people would just go elsewhere for their fix of confirmatory nonsense. This 30% is the part of the population who are twisting Society their way. It is a hard nut to crack.

      I came across a fascinating clip of Harrabin’s acceptance speech for his hon. Doctorate from Cranfield. He offered the idea that telling 73% truth is good enough, on the grounds that it is better than not saying anything.

      It’s an interesting way to justify wrapping a 27% of story propaganda lie in a clothing of truth to enhance its credibility, and an insight into his mindset.

        “Better than not saying anything” is exactly why journalists are such a self centred bunch of hypocrites.

    Amazingly, even the Guardian is a little more balanced than the BBC regarding Storm Hilary:

    …“To my knowledge, no one has ever done a formal study on tropical cyclone hazard in a warming climate in California,” Swain said. Because California’s geography is so different from other parts of the world where hurricanes are common, studies from elsewhere don’t provide reliable insight into what is happening now.

    While it is plausible that much warmer temperatures in the eastern Pacific could give rise to more such storms, the unique topography and wind conditions in California would still impede them from making landfall there, Swain said. Such storms “will remain a rare event in any foreseeable future”, he said.

    “If this were MythBusters I think it might get stamped ‘plausible’ that climate change could increase the likelihood of events like this, but probably not to a very high degree,” he added….

    Ex Hurricane Hilary made landfall in southern California as a tropical cyclone. 1 hour 17 minutes later it was downgraded to a post tropical cyclone, but the MSM still ran with the headline ‘first tropical cyclone to hit California in eight decades’. As Paul points out, the rainfall from this post tropical cyclone is not unprecedented either. There’s nothing unusual about Storm Hilary.

    I do love the claim about increasing frequency! A 100 year event happens ON AVERAGE once every hundred years. So in 1,000 years, there will be ten. But they aren’t evenly spaced out.

      “The term “100-year flood” is used in an attempt to simplify the definition of a flood that statistically has a 1-percent chance of occurring in any given year. Likewise, the term “100-year storm” is used to define a rainfall event that statistically has this same 1-percent chance of occurring. In other words, over the course of 1 million years, these events would be expected to occur 10,000 times. But, just because it rained 10 inches in one day last year doesn’t mean it can’t rain 10 inches in one day again this year.”

        Under simplified assumptions the probability of no recurrence in N years becomes 0.99^N. So that’s about a 5% chance of a recurrence within 5 years, 9.6% within 10 years, 22.2% within 25 years, 39.5% within 50 years but still only 63.4% within 100 years. There’s a 4.9% chance of going 300 years with no recurrence.

Sadly ‘prestige’ does not equate to ‘knowledge’ and our MPs are generally too ignorant to ask the right questions anyway.

        I believe tetraethyllead was one of the greatest inventions of all time. I read many years ago that using TEL to get octane up, instead of more highly refining the fuel, saved 6%. 6% of U.S. oil is probably more than a hundred countries have ever used in their entire existence. I wish I knew what that is in cubic elephants.

        I never bought the theory that the trace amounts of lead in exhaust gases were enough to affect anyone.

        The Left has a LNT view of lead. People can have some lead without any affect at all. Dangerous levels are rare.

        Aside: I knew some people from Ethyl Corporation when I worked up in Richmond. Good people. They are still in business making fuel additives, but probably not much TEL anymore.

    ‘Hurricane’ Hilary wasn’t even a hurricane when it made landfall.

    Hilary was downgraded to a tropical storm a few hours before making landfall, as rain from the storm started spreading in Southern California, the National Weather Service said. Then it was downgraded again, to a post-tropical cyclone early Monday morning. The system was expected to dissipate later in the day but still produce heavy rainfall, significant flooding and gusty winds across the western U.S.

    As of 8 a.m. PDT Monday, Hilary was about 115 miles west-northwest of Elko, Nevada, and racing north-northeast at 24 mph with maximum sustained winds of 35 mph.

    Having spent some time in the desert SW of the US in the 1990s, the phenomenon of the ‘summer monsoon’ was a feature of the climate. Perhaps not in California itself – usually – but slightly further east in Arizona, you had to be prepared for flooding on desert roads (where there were no bridges across ‘washes’) and as a hiker you were cautioned about entering ‘slot canyons’ in any of the desert states because of the risk of flash floods. Drownings did occur each year. Typically these floods were caused either by tropical storms coming north from the west coast of Mexico (as in this case), or sometimes from tropical storms or former hurricanes coming in from the Gulf of Mexico. Sometimes also it was just isolated thunderstorms.

    This is so funny. I live in San Diego and it was the biggest nothingburger. Yes it rained all day Sunday, but not hard rain, more like drizzle, and no flooding near me (when it usually floods every winter from rain). The wind wasn’t bad either, about 5-10 mph.

    Most reports from the BBC which seem to be directed towards climate change are sensationalist. The BBC remit is that they should be impartial. In many areas of reporting they are very much less than impartial and certainly don’t give an alternative view if it doesn’t agree with their agenda.
