After Graham's recent post I'm starting to feel a bit uneasy now, despite my
being in shelter. Wind is picking up gradually and pressure is falling rapidly.
Recent gust 48 mph at 10m agl with mean speed 20 mph. I don't like that gust
factor of 2.4. Sleepless night ahead I feel.

Somewhat more benign (at present) down the hill.

Max gust to date 17KT.

Current (2-min) mean wind 4KT....OK, my site is well under exposed.

Pressure is falling rapidly (1005.7 hPa at present).

Temp +11.8 deg. C
DP +7.1 deg. C

Regards,
Richard.

Dartington, South Hams.

Will, the 12Z NAE had gradient winds of 60-70KT ahead of the cold
front/occlusion and 80KT or so at first tonight. Line convection was also
evident with a non-zero risk of tornadic activity (your diagnostics have
already signalled low PROBs in the far west). Also of note were 50KT 10m
winds in the southern Irish Sea/western English Channel tonight and then
later tomorrow in the northern Irish Sea. As per
http://www.weather.org.uk/charts/UKCpf024.gif
Potent stuff with the key uncertainty being what percentage of the gradient
winds will be realised at the surface, particulalry inland.

Now gusting 55-60 knots at John Chappell's site near Land's End.
Gusting to 50mph here in Penzance, and increasing steadily.

Cheers Jon. Confirms my earlier suspicions that any damaging gusts will be on
the front itself.
Fortunately for me the hills to my west tend to break up frontal structure a bit
when they come in from that direction.

Thanks for info Graham. Take care, it looks like it may be getting nasty out
your way.
Wind has actually died down a bit here in past 15 minutes, but it will pick up
again for sure.

Shut up Will...

Since my last post we are just about at F8, gusts to the mind 40's and
the pressure is really starting to nose dive. 3mB in the last 60 mins,
4mb if you make it 75mins...

I don't like that gust factor of 2.4. Sleepless night ahead I feel.

Just the normal 10mph or so above the mean here.

Not looking good, with high wind gusts this early.
64kts recent recording just off lands end

Check out the sat loop animations. Vicious hook already well defined

With all the widespread Violent Storm 11's in the shipping forecast,
let's knock two catagories off that for land.... that would still be
severe gale 9

My concern is this storm could turn out a wee bit stronger than
forecast
At this point, hurricane force gusts are looking likely

Very eventful 24 hours coming out.... and of course no sleep tonight
