Further revision downwards -

Now 53 knots (61 mph) estimated for 10m. (There was still a mistake in
calculation).
Fits in well with forecast I did yesterday too!

Not been my best day due to lack of sleep :-(

Re other thread.

After some work, some thought, and looking at other data/damage in area etc I
have revised my 10m gust estimate downwards to 57 knots or 65 mph (still a
personal high) .
41 knots at 3m measured (previous highest was 32 knots).

Cheers,

Will.

What a night.
Front came through at 0415 with a temperature drop of 3 degrees and a
massive
gust of 68 knots (81 mph) calculated at 10m agl, recorded 3 metre gust was
41
knots (49 mph). I did say I expected the strongest wind to be on the front.
This
is my highest recorded gust so far. I am relieved to say that there has been
no
damage to the house as far as I can tell. That was higher than expected as I
am
fairly sheltered from the south. Rainfall 30 mm BTW.

Will.

Chosing the best site for a low-level anemometer is extremely
important. For example, in any wind situation, using a hand-held
(cica 2m) anemo, I can get a very wide range of values. As low as 1%
(stand in the lee of a building) to 60-80% above (look for funneling
effect) that of the 10m value when the correction for height is added.

Couldn't agree more Dave. Depending where you stand around this house is
the difference between "Wind, what wind?" and being knocked of your feet.

The layout of the house and barn is "L" shaped with the point of the "L"
into the prevailing wind direction and I doubt that that is coincidence.
Stand in the crook of the L and it might be a bit blustery but that is
all. Stand at one of the extremities and be careful. Walking out past the
end, forgetting it's windy, can be a very nasty surprise.

Luckily we managed to get a few essential supplies in by air last week
- fresh fruit. Keep scurvy away? No - included lemons for the G&Ts!

Lemons = citrus fruit, will keep Scurvy away. Scurvy is lack of vitamin
C.

Mind you ... were rapidly running out of beer as well as other
'essential' (liquid) supplies!!

Now that is *FAR* more serious. B-)

I was reading about your ferry recently, Dave. Designed like a trawler
for the rough crossing. And the cabin seats have airline-style seat
belts. Makes our RORO crossing look like a trip on a boating lake!

Exactly. Which is what I said before. He is not actually on Dartmoor,
he is on the southern jessie version of Dartmoor, which is as close to
a supermarket as he can get.

60mph and you have a sleepless night?

FFS we dont actually want these kind of people pretending to be hardy
hillside locals.

90 mph will come within 5 years, mark my words.

Not a boat day today - pressure of 960hPa or less over the area does
not help subdue the sea! However we did get in two inter-island
flights (no freight). The first one was fine as the wind was just
13kt from 210deg - not much off the runway heading of 240 and a
smooth profile up the Isle. Not so the second flight! With the low
centre moving north the wind had veered 290deg and increased 23kt gst
33kt. Landing was OK, but the take-off rather heart-in-mouth as,
coming across the high west cliffs and with CB development in the
neighbourhood, the wind was very 'fickle' - real seat of the pants
flying!
Hopefully a boat day tomorrow. As there are no passengers booked the
crew can rough it a bit!

Again, Mr Hindsight is the best forecaster! I had a look at the radar rainfall
imagery in some detail today. Strong evidence of line convection on the front
and (as Jon mentioned) an 80 knot (92 mph) gradient wind. Bring that down in a
convective downburst and you have havoc, indeed worse gusts than the 1987 storm,
but obviously not lasting long in any one place. Parts of Plymouth had over 90
mph gusts and the damage runs into millions of pounds according to Spotlight (a
lot it yachts of course). So OK quite localised and it won't be rembered for
long but *potentially at the time* it was a serious developing situation. As for
moving, not a chance, I'm here to stay, I love the wild weather and walking in
the hills, but I reserve the right to get anxious when it blows and line
convection beckons, who doesn't to be honest?
