I’ve never felt an earthquake before but I have now! At almost precisely 1430 UTC we felt the effects of a magnitude 4.9 earthquake down here in Devon. The epicentre of the earthquake itself was apparently in south Wales (fig 1). At the time I was sat in my office chair – programming as usual – when it started a series of wobbles to-and-fro – very unusual!
You really couldn’t make this up, but today’s full moon will be depending on your location:
- A wolf moon – because I’m reliably informed that’s what they call full moons that occur in January.
- A blue moon – because it’s the second full moon in a month although this is open to debate because over the years the original idea has been lost.
- A blood moon – because in some parts of the world a partial lunar eclipse will occur, and turn the blue moon a little bit redder. I always thought blue and red made green so who knows. Unfortunately the eclipse won’t be visible in the UK, because the skies will be perversely clear for once.
- A supermoon – because the moon will be around 7% closer than normal and 30% brighter.
The other interesting thing is that because of the blue moon in January, February 2018 won’t see a full moon, and that only happens four times each century.
During tomorrow it’s certainly set to become very windy and wet over large parts of the British Isles, but I have my eye set on developments during Friday and into Saturday, which if they pan out as the GFS suggests, might well bring a spell of snow to central and eastern counties before the deepening low exits into the North Sea during Saturday morning. Gradients around the low tighten considerably, even if a lot of that gradient can be discounted because of cyclonic curvature (fig 1).
The only thing I can get out of the Met Office is this T+120 image (PPVO89.tif) for the same time (fig 2). The Met Office model is much faster with this feature, and the low ends up being much more elongated and +5 hPa shallower than in the GFS.
Somewhere in the UK could see a maximum temperature as high as 20°C this afternoon, in the super mild air behind the warm front that’s pushed northeastward across the country today. The all time maximum according to TORRO for the 24th of October is 21.7°C at Prestatyn in Denbighshire so that looks safe.
I installed Thunderbird on my computer a few weeks ago, after using Microsoft Outlook as my email client of choice for many year. For some reason Thunderbird flags absolutely everything that I receive from the Met Office as junk, and labels each message ‘This message may be scam’ in red. I can’t help wondering if Mozilla know something I don’t know about the organisation! By the way I’m rather impressed with Thunderbird and wished that I’d made the change much sooner, best as well as being free it’s not cloud based!
I notice that there are a couple of reports of gusts to 64 knots along the south coast of Ireland at 09 UTC. That’s hurricane force 12 on the Beaufort scale for mean wind speeds (fig 1). I notice that at the Weather buoy K1 last hour there was a wave height of 11.1 metres (>36 feet) reported, the pressure has now bounced back there amazingly from when Ophelia passed close by to the west or to the east (fig 2).
