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.

Hi, Will,

I'm a bit confused with this. My Met O Observers Handbook states that
only mean windspeed should be adjusted to an effective height of 10
metres. Gusts should be reported as read with no alteration.
Has this changed and am I living in the past yet again?
49mph gust at 9 metres agl here, so nothing special yet.


Ken, you may be right I'm not that well up on observing regs as I am not an
official site. However, I have corrected the gusts in the WRs as it seems
scientifically sensible to do so in order to compare with others. I admit that
correcting is not perfect and one day I shall have an anemometer at 10 metres,
then all doubt will be removed.

Cheers,

Will.
