This headline could really use the word "hurricane" in it. I had no idea what Otis or Acapulco were, and my initial guess was wildly off: some sort of space probe experienced a catastrophic failure on the way to an asteroid.

From the url it seems the target audience for this blog would already know

I imagined that a prototype device of some sort that was being shipped to Acapulco pulverized the truck or ship that was transporting it

"Otis" was also the name of a Kanye West/JayZ song so I was thinking maybe it had something to do with that??

This song was a tribute to Otis Redding. My first thought was that the article was about him lol.

Does Acapulco airport not have radar because the ATC for that part of Mexico is at Mazatlán?

i’m not an expert in this area myself. your comment made me curious though. chat gpt (GPT 4) helped me understand better: https://chat.openai.com/share/9448215d-2b65-4611-a634-f1a900...

Those locations are nowhere near Acapulco.

Cloudflare blocked me from accessing it. edit: wow, that was some unexpected downvotes

It's just completely irrelevant to the article. Would you have posted a comment if your ISP was down?

For me it is completely relevant to the article because it make it impossible for me to read for no legitimate reason.

Even if the site was down for everyone I would comment. Lots of people comment about “hug of death”, for example, and I find it very useful. I know it is not me and I can find an alternative.

And since it’s not down for everyone, only a few, for a new, odd, technical reason, I find it even more relevant to comment about it.

Just like it is useful when people comment when a site is not accessible from a certain country, like BBC sometimes or some YouTube video.

I see these comments often on HN and I always find them useful. They also usually are among the top comments, so likely not downvoted.

That said, I was premature in editing the comment to show my surprise in being downvoting. That, indeed, is against HN etiquete and also it was just some temporary state, since I got many more upvoted since then.

there is already a very good theory. see this interview with an expert from Yale: https://youtu.be/CSVFpval4Dw?si=oelutbqzOGcpI8gm tldr: garbage data into the model, garbage out. Detailed summary from interview: • only 1 hurricane hunter flight was done into this storm. • mexican hurricanes just don’t get as much reporting coverage (historically). For example for atlantic hurricanes, NOAA hurricane hunter airplanes h…

I meant ATC sector HQ, of course Acapulco has a tower.

> Otis intensified so quickly that it basically outran the ability to measure how intense it actually was.

We're working on this problem at Care Weather (www.careweather.com). Current wind sensing satellites only measure ocean surface winds once per day. They're too expensive for governments to build additional satellites for more frequent refresh. We're lowering their cost by three orders of magnitude and launching a constellation to get hourly updates.

> So how did every reliable model we use miss this? That’s for graduate students and researchers to answer in the coming years, because I have no formal idea. Would love to see followup on this. Wish there were some way to like bookmark or something and come back in a few years.

Yep, I commented here that my company, Care Weather, is working on that problem. Goal is to provide hourly updates of ocean surface winds.

> Anybody who understands what the big words 'climate change' mean, could have predicted this. HAVE predicted this. I personally have predicted this and I'm not even a weather forecaster, I just know what chaos theory is. This is a bit of a strawman. It's not that "no one thought this was possible". We've known that we will be seeing storms that are larger, stronger, and faster forming than what we've seen before. It…

I think it's wrong to imply that the current tools are 100% useless. I've seen a guy on youtube drawing on apparently elaborate weather models from multiple sources and they're just the sort of thing that would highlight the risks. This guy (Ryan Hall (y'all)) has repeatedly highlighted the high sea temperatures in the Gulf of Mexico, stressing that they could produce rapid intensification of hurricanes, several time…

Sorry, I didn't mean to say that the tools were 100% useless broadly speaking. In this specific event, they were. The chart says it all: https://theeyewall.com/wp-content/uploads/2023/10/102623-int...

That's nine different prediction models, of which zero predicted anything resembling reality.

Sure, there was less data available than in other areas. Sure, there was less ground radar. Sure, fewer eye flights were made. But there have been other storms with a similar dearth of data; never before have all predictive models been so very wrong.
