Question:

From a damage standpoint... is there a difference between 157 mph winds and say... 200 mph winds or even 250 mph winds? Seems like it'd be no different than running your car into a brick wall at either 150 or 200 mph... damage is essentially the same.

Why There's No Such Thing As A Category 6 Hurricane
quote:

Hurricane strength is rated using the Saffir–Simpson scale, first developed in 1971 by Herbert Saffir and Robert Simpson, a civil engineer and meteorologist respectively. While flooding can account for much of the lasting damage a hurricane can cause, the Saffir-Simpson scale is concerned solely with windspeed, using the max speed of sustained winds to organize hurricanes into the five established categories:

Category 1: Very dangerous winds will produce some damage.
74-95 mph winds.

Category 2: Extremely dangerous winds will cause extensive damage. 96-110 mph winds.

Category 3: Devastating damage will occur. 111-129 mph winds.

Category 4: Catastrophic damage will occur. 130-156 mph winds.

Category 5: Catastrophic damage will occur on a large scale. 157 mph or higher winds.

The potential for a Category 6 storms seems obvious. ... It's a moot point however, because the Saffir-Simpson scale is not designed to arbitrarily classify storms into tiers based on wind speed or some sort of abstract power level. The Saffir-Simpson scale is designed to reflect the damage a given storm will cause to buildings and other man-made structures in its path. Category 5 is widespread, catastrophic damage. There's not really anything worse than that.

There’s really no purpose in adding an extra category other than to just make storms sound even more scary. It’s not like the category on a man-made scale is what gives the storm its strength.

I mean, the percentage of tropical systems that reach Category 5 strength on the Saffir-Simpson scale is already quite small.

depends on structures and what theyre made to withstand. something could be built to withstand 157 but not 200. Generally speaking the damage is devastating either way,yes, but youd definitely expect more of it from a 200+ storm.

This is annoying and not helping with insurance rates in LA.
Bunch of camps get demolished in Laura and Ida and now everyone south of I-10 is paying for it.

Why stop at 6?


If they’re going to frick with us like this, then I’m going to start using my own categories.

“How big is this hurricane?”
“John Holmes “.

I see they just want to add on not adjust the lowers.

I dunno about that......we had a 72mph Cat. 3 hit the big bend area of Florida just last year.

It’s my understanding that wind gauges used to measure speeds from storms 40+ years ago were often destroyed from the winds they were recording.



So much has changed since then and this is my reasoning as to why much of the "never seen before" rhetoric is not accurate. When we have the most storms in a season, is it because we had the most or because we just didn't have the satellite technology to identify 3 to 5 storms that started and spun out quickly in the middle of the Atlantic without being spotted and measured by a plane or ship?

This is worthy of another thread, and probably will get one eventually.

"They" didn't start naming Winter storms, The Weather Channel did.

I like this. Nothing has changed and it’s in no way fear mongering which is why most changes are made. These inland hurricane/ts warnings have always been issued so it’s good to see them finally go on a graphic. Honestly strange they were never on there in the first place.

Yeah, they're consolidating products that were already publicly available. Most people only see "the cone", and too many fail to account for the size and scope of a storm. They see that center line, see they are twenty miles away from it, and think they're fine.

This at least makes that information more readily available without having to do any further "digging". I'm sure there will be issues with it, though, like always with messaging changes.

How about we wait until we actually have a storm that warrants this.

They can't wait to trot Jim Cantore or some other personality out in a rain suit.
