Ophelia – 13 UTC

Figure 1

I reckon the very worst is now over for the south coast of Ireland, the wind has veered southwesterly and although it’s still gusting to more than 80 mph at Roches point the gradient should start to open a bit as the wind veers a little more into the west. Massive pressure rises over Valentia in the southwest now pushing Ophelia north-northeast where it should finally make landfall in county Clare or Galway. I see Weybourne in Norfolk reached 23.2°C at 13 UTC so it did break the warmest day record. By the way the contouring can’t handle Ophelia at all well but you probably already noticed that.

Met Office scam

Figure 1

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!

Yes Tor and the appliance of science

I thought that I would download the latest Camborne ascent and see what all the fuss was with all the talk of warm air over the higher hills, but unfortunately the 12 UTC didn’t fly, so I had to make do with the one launched just before midnight (fig 1).

So basically if you hiked your way up to the top of Yes Tor from Meldon reservoir just before midnight last night, there would be some good news and some bad news:

  • The bad news is that you would probably be blown over by the southerly severe gale force nine that was blowing at the time.
  • The good news is that the temperature would have been around 22.7°C so you could have done it in the nude.
  • The extra bit of good news is that if you had taken your washing up with you to hang out, it would be have been dry in extra quick time because of the strength of the wind and the low relative humidity of 30%,
  • The extra bit of bad news is that you would probably have to drive to Okehampton before you could pick it up!

Isn’t science wonderful!

23.2°C at Manston equals the warmest 16th of October on record

Figure 1

There’s nothing quite like the British weather, with gusts of 67 mph on the Scilly Isles in the west on the 12 UTC chart (fig 1), and temperature of 23.2°C in the east at Manston, which more than likely makes it the warmest 16th October on record. In Ireland the storm force winds continue, and are still gusting in excess of 90 mph on the south coast, as Ophelia tracks slightly northwest of Valentia on the west coast, what about this for a pressure kick (fig 2).

BBC News: It’s official, this morning’s blood-red sun was caused by Saharan dust

It’s official! This morning’s blood-red sun was caused by Saharan dust, so says Simon King the BBC weather presenter.

Storm force 11 at Roches Point and gusting over 96 mph

Figure 1

It’s a good job Met Éireann wisely decided to up the status red this morning because the wind has been gusting to 96 mph at Roches Point on the south coast of Ireland (fig 1), and meaning 62 knots – that’s storm force 11 and just two knots of hurricane force 12 – at 11 UTC. Ophelia has still to make landfall, but must be very close to Valentia now, where the pressure at 11 UTC was 962.3 hPa and fell 9.6 hpa in the last hour.

Is Ophelia regaining an eye like feature?

Figure 1

It almost looks to me that ex-hurricane Ophelia has managed somehow to develop an eye like feature in the 1045 UTC visible satellite image. I did at first think that it maybe a shadow, but it does have the distinct appearance of an eye to it. A better quality satellite image would settle it but of course we can’t access hi-res rapid scan imagery can we. Please don’t bother commenting t o explain that hurricanes can’t survive in the cold waters around the UK without reading this article about Hurricane Debbie in 1961 first!

Storm force 10 at Roches Point gusting 70 knots

Figure 1

There’s a storm force 10 south-southeasterly blowing at Roches Point with gusts to 70 knots on the 09 UTC chart (fig 1), Ophelia is still to the southwest of Valentia, where the pressure is falling like the proverbial clappers (fig 2).

First a yellowish sky and now a red sun whatever next!

I’ve mentioned in several of the postings I’ve made this morning about how yellowish the clouds have been ever since dawn here in Devon. Well my neighbour has just knocked at the door to say just how reddish the sun was as he drove back from Cullompton just now. So I broke off from blogging and managed to capture a couple of pictures of it as it was just starting to poke through the thinning sheet of CS. I did pooh pooh the notion that it was Saharan dust that was causing it, but now I’m not so sure. I apparently missed the sun when it was at its reddest which is always the way of it!

Figure 1

Apparently the red colour of the sun this morning in Devon is partly the result of Saharan dust, and may explain the warm air over western Iberia yesterday.

Gusts to hurricane force 12 on south coast of Ireland

Figure 1

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).
