    Cat 5 strips the land bare under the eyewall. Admittedly, there's some variation in building standards, which means that the idea of how much damage is caused by the various categories can vary from place to place, building to building.... but yeah... Cat 5 scours the surface of the earth over an area at least as wide as the eye... or at least that's the idea (and if you look at before and after images of Barbuda, the colour change says it all)

    Indeed, much too early. Lulls in activity are normal, and an eruption is said to be continuous if it occurs within 3 months of the beginning of such a lull, and is not distinctly of a different type (eg, different magma chemistry). Alas, we'll know when we know, and I wouldn't be counting any chickens before then.

    There have been bigger, and there have been stronger... but it's also going to be a lovely summer storm in the UK, so I figured it's worthy of its own thread.

    What? No thread for Hurricane Chris (https://www.nhc.noaa.gov/archive/2018/CHRIS.shtml?), or subtropical Storm Debbie (Current, but not for long!)? I know the Atlantic's quiet, but it's not THAT quiet!

    Guess who's back? Back again. Beryl's back....

    The NHC map says TS, but the forecast advisory (2100z) refers to Hurricane Chris in the title. Methinks it's been upgraded, but I'm not sure. Either way, the tip of Newfoundland takes the brunt of it. EDIT: Confirmed. 5pm EDT discussion declares an upgrade to Hurricane status. Now lets go spin some fish!

    OK, so I just watched a recording of the KFOR live broadcast of the Moore (OK) tornado. In that case, in no time at all it just went from a black dot on the doppler radar to a purple dot, within a cell that had hooked from the main storm and separated off. Just after the change in colour in doppler, it was heading into an area with nothing but trees and grass, and also a lake. The extensive debris cloud cleared, the wedge took on more of a barrel shape, the barrel got thinner and thinner, and it finally "roped out"... ie, turned into a twisting and turning rope-like vortex, which finally just dissipated as the tight circulation broke down despite the feeder bands still feeding, and the storm above stil rotating. So now I know. I don't know if they all end this way, but it's an answer and I'm satisfied.

    So, I've just been considering some of the big F5 wedges in the last couple of decades, having been watching some youtube videos. We've all seen footage of a tornado touching down before it grows... ... but how do they typically dissipate? Presumably it's a boring process, as nobody ever shows it on video... but what's happening? Do they get separated from the main cell and just kind of peter out once the energy driving them isn't there anymore... do they thin again and rise back up into the clouds as a disappearing funnel? Or do they just sort of thin out like an evaporating windy mist? Obviously I'm referring to the big ones here, but what causes them to finally give up, and how do they end?

    Seems to have been quite active this season... wouldn't be surprised to see a season on the quiet side coming up. That said, if we don't see many hurricanes, I expect to see at least one of the majors being pretty darned major. That heat has to go somewhere!

    And over Coventry.
  12. crimsone
    6pm. Coventry. Snow. We had some. Dusting on the pavements, and where the traffic doesn't run on the roads.
  13. crimsone
    I have to say, I'm loving the 50/50 chance of "torrential" snow in Coventry next thursday.
  14. crimsone
    Stich get tends to occur just on the outside of a frontal hook, so I'm not sure you'd see it on a slp chart. Alas, I do not have a eurosat link. I'm sure someone else here does though.

    Is the new one a fully fledged system yet? They might have a little dance. https://en.wikipedia.org/wiki/Fujiwhara_effect#Extratropical_cyclones
  16. crimsone
    You should propose that as the proper terminology for it to Met Eireann, right away! lol
  17. crimsone
    On a rather serious note... some deaths many of us probably hadn't considered...
  18. crimsone
    ... and more importantly, what happened to the wifi west of Scotland?
  19. crimsone
    Huh. According to Met Eireann, the fastest gust today was at Fastnet Lighthouse, not Roche's point as I erroneously said earlier - 191 km/h (118.682 mph)

    ~If~ they were freshers, they quite probably didn't know any better. They sure as hell do now though!
  21. crimsone
    Looks pretty dry at the start of that video. What's probably happened there is that a group of inexperienced freshers decided that the ground looked dry so they'd have a watch. They won't be doing that again. I suspect they they're freshers because the locals will know that just a little while back, large portions of the seafront were wrecked by crashing waves.
  22. crimsone
    Don't know if there was anything higher after that. Works out to around 68 mph mean wind, and 118 mph gust.
  23. crimsone
    I see that local media is as awful as ever. http://www.chroniclelive.co.uk/news/north-east-news/hurricane-ophelia-how-can-you-13768532
  24. crimsone
    Ex-Ophelia has had a max gust (last time I looked) at about 118 mph... compared to '87 having 115 mph. '87 went down to 960mb, while Ex-Ophelia has recorded 959mb Haven't seen a max mean wind for Ex-Ophelia yet, but in '87 it was 72.5mph (1dp) The storms are of similar strength.

    No warning is going (usually) to be relevant to every spot within the area, but on an area wide basis, this seems to me like a pretty significant impact... https://www.scribblemaps.com/maps/view/Northern_Ireland_-_Live_Flood_Warnings__Weather_related_incidents_/b5tcCpgGqK
