Sharkicanes?

Since 1980, five storms have hit the hypothetical Cat 6 threshold of 192 mph….None on record before then.

I wonder how much of that is due to not having the ability to measure the speeds, vs anything to do with global warming, (not saying I don't believe in global warming and our role in it) but it's similar to how some people think mental issues like ADHD or Autism and even things like gender dysphoria are on the rise, when in reality a lot of it is just better methodology and tracking of diagnosis.

You make a fair point, but even assuming this level of hurricane was occurring previously, at least we can now monitor their frequency moving forward.

Edit: I just read the article, and it indicates all such recorded hurricanes were within the last decade

Most speed calculations are made by the analysis of pressure at the storm's core. Hurricane hunters measure that.

“If there are things that emergency managers would do differently, or the public might do differently because a storm has 195 mph winds versus 160 mph winds, then maybe the categories should be changed,” he said. “Personally, I’m getting out of the way if it’s 165 mph winds or 195 mph winds.”

A valid issue, there's not much point to adding a category if there's nothing extra that needs to be done for it.

Still, though, I can imagine there being a few possible issues. If a hurricane is strong enough that it's going to literally level a city completely, like the 1900 Galveston hurricane that killed 8000 people and is the reason that Houston is the biggest city in Texas instead, then that might change some decisions when it comes to how to go about evacuating. I don't live anywhere that a hurricane would ever hit, but if I knew "my house is likely to be damaged or maybe collapse" versus "my house is going to be erased so thoroughly you'd need GPS to know where it once stood" then I'd put different stuff in my car before getting out of town.

The category may help estimate the damage before it happens and allow for some planning.

Good news! Florida is FUCKED!

Bad news! Displaced Floridians spread their methhead redneck energy all across the country sea to boiling sea

Yeah. It’s so awesome when innocent people die because the hive mind has decided that an entire state full of people’s lives are inconsequential in comparison to their shit sensationalist views!

There’s lots of good people in Fl. Go home, edge lord.

Let's not get carried away. There are some good people in Florida.

You can’t say that type of thing here. The kids don’t like it. Chances are, the lemmy authorities have already been called and your comment will be removed.

I’m curious what the guidelines would be as a preparation for the potential of a new category. Like leave the area? I know changing how we do things now on a global scale should help, but in case and due to cynicism, it might not help. But what should people do for the seemingly inevitable storms?

Physical fitness helps. I'm just as guilty as many of my fellow Americans when it comes to letting the numbers on my bathroom scale creep up over the years so won't be sitting here preaching routines and stuff. Some stretching and general work on flexibility should go a long way though.

Everyone's starting point will be different but with some persistence and dedication to a steady routine, results will start showing before you know it. Once the storm hits, you'll be much more capable of bending over to kiss your ass goodbye.

Lol I can't tell if this is a joke or not but either way super funny.

Mostly a joke with some elements of truth. If you're getting turbofucked by nature's fury, being able to move on foot for long distances when needed puts you in a better position than someone who is less able. From a response resource point of view, people who can escape the immediate danger on foot free up vehicles and rescue personnel for others with mobility issues.

Wroooong. Become a climate denier. That way when the storm hits you can just pull your head out of your ass to kiss it goodbye.

The guideline is: Kiss your butt Goodbye

Excellent point.

Seriously though....the old saying "Run from water, hide from wind" still applies. At that strength, a Cat 6 is like a 20+ mile wide tornado. So, a lot of hiding if you're anywhere near. And if you're in the direct path there is little you can do.

Your question gets to the heart of why it's not important to add another category. Once you get a truly monster storm, a lot more factors come into play as to how dangerous it is than just wind speed. There's not a single band aid solution.

It's why they stopped at 5. Everything was gone anyway when it hits. In a category six it's even more gone so it didn't make them much sense.

North east coast of Australia gets hit with category 5 cyclones every 5 to 10 years or so, there are plenty of buildings that survive that.

Parents copped the brunt of Cyclone Yasi with 180 mph gusts, only damage to their house was they lost a section of guttering, it was peeled off never to be seen again.

Building standards there are rigorous. They built their house themselves (in a rural area, 180 acre farms), its engineering design was required to withstand wind loadings of at least 70m/s (160mph) .

It is a steel-framed, single story kit home, on a steel piling foundation about 3 feet off the ground. The local building inspector also told them to put long threaded rods from the roofing trusses to the subfloor and the foundations while building it and tension them up, they eventually put in 36. This effectively ties the roof to the foundation and stops it peeling off, once your roof comes off the rest of the house usually folds up like an open cardboard box.

Apart from losing the section of guttering, there was no other damage to the house. They boarded up the larger glass sliding doors and were somewhat alarmed at the amount of flex on the glass as the cyclone passed, but they held up ok. They didn't get power back for two weeks , which was the worst of it for them as it's very humid afterwards, they had a generator and ran it in the evening to power the aircon in their bedroom each night until it ran out of fuel.

Possibly? Our building techniques have improved since the scale was originally finalized so it may make sense to have a category for our truly hardened structures.

Floridian here. Anything over a cat3 heading your way is cause to GTFO immediately or seek shelter in an evacuation shelter (usually sturdy public buildings like schools). You can usually weather the storm if it's cat 1 or 2 and you're well prepared and don't live in a flood zone(even then there's room for exercising your discretion). same goes for 3 but at that point I'm tracking the storms path to see if we're gonna get a direct hit or not. If it's on the low end of 3 and we're only getting the outer bands I'll stick it out. If it's looking like a direct hit I'll leave. Never been hit by a cat 4 or 5 and have no intention of being around when they come knocking. A cat 6 would be "if you're still around you're a fucking idiot" level of storm.

I did stick around for irma or Michael a few years back but only because by the time they were near me they were going to be significantly weaker than when they made landfall

Well categories 4 and 5 already recommend evacuation for everyone in the path. There isn't a viable response more extreme than that we're capable of. Perhaps evacuate sooner? But we have a lot of trouble predicting hurricane movements, especially as they approach land.

Category 6 - Don't expect to come back to anything. Whatever you take with you is all you'll ever have.

It kind of triggers the mind with new state input. So more psychological. But it's understandable, as a new category can encompass not just wind speed, but whater dropped, storm surge, and other factors that are amplified in Cat5 in a higher carbon atmosphere.

Also have to consider Cat5e which, due to its higher number of twists per inch, ends up being capable of much higher speeds without crosstalk.

Honestly you should be moving to Cat6 hurricanes and deprecating your Cat5e, since 2.5 gigabit Ethernet wind speed is becoming a consumer-grade thing.

Both Cat5e and 6 can deliver solid PoE which is good news for the inevitable power cuts.

This just seems weird. it's a "study" but it's just some guys making a list of hurricanes that exceeded 192 mph winds and saying "these should be in their own category", and I'm assuming they didn't pick 200 mph because the list would then be too small. They're also ignoring historic hurricanes that hit that, https://hurricanescience.org/history/storms/1930s/LaborDay/

A good reason to start building homes underground.

That is the last place you want to be during a hurricane...

Now super armored dome houses...that's where the money is.

Rich oil executives are way ahead of you

Good news for those who want their storms like their networking cables.
