Default Is my Silver Birch Safe?

The message
from martin contains these words:

Force 9 is about as strong as it gets in UK most of the time, Force 10
is rare.


That depends where you are in the UK.

You can reckon an average of two hurricane force winds a year in the
Utter Hebrides. Here in East Angular I've only seen one.

We have some opposite our houses which were planted in the late 1930s.


but then again you don't live 5 miles from the North Sea coast in a
flat landscape, the ground is sand not soil, with frequent force 8 and
9 gales in autumn and winter.


Nor does Bilbo, I'd warrant.

Its a wind of 47-54 mph.


Eh?

West Scotland had gusts


"gusts" Wind forces in weather forecast are average.



of 60 to 70 mph this week,more forecast for
tomorrow,


The forecast is for force 8-9 i.e max 54 MPH

THE SHIPPING FORECAST ISSUED BY THE MET OFFICE
AT 1130 ON THURSDAY 09 OCTOBER 2003

THERE ARE WARNINGS OF GALES IN VIKING FORTIES CROMARTY FORTH
ROCKALL MALIN HEBRIDES BAILEY FAIR ISLE FAEROES AND SOUTHEAST
ICELAND

THE GENERAL SYNOPSIS AT 0700
LOW 150 MILES SOUTHWEST OF ICELAND 970 EXPECTED FAIR ISLE 982 BY
0700 TOMORROW. HIGH 250 MILES WEST OF FITZROY 1029 MOVING SLOWLY
EAST AND DECLINING 1022 BY SAME TIME

THE AREA FORECASTS FOR THE NEXT 24 HOURS

VIKING
MAINLY SOUTHWESTERLY 5 OR 6, INCREASING 7 OR GALE 8 IN SOUTH. RAIN
OR SHOWERS. MODERATE OR GOOD

NORTH UTSIRE SOUTH UTSIRE
SOUTHWESTERLY 5 OR 6, OCCASIONALLY 7 LATER. RAIN OR SHOWERS.
MODERATE OR GOOD

FORTIES CROMARTY FORTH
WESTERLY 6 INCREASING 7 OR GALE 8, PERHAPS SEVERE GALE 9 LATER.
RAIN OR SHOWERS. MODERATE OR GOOD


which is nothing unusual at this time of year, and nowhere
near as strong as winter winds.


Statistically for most locations in the UK the probability of a force
10 occurring on a particular day is low. Happy?

Because of the UK's shape and position it gets weather extremes.

Getting back to silver birches, if they are planted in sandy soil in
an exposed location, where there are extreme winds, then the wind will
eventually uproot them, especially if the leaves are still on the
trees.
