I think the winds in the NW are a teentsy bit faster than 50. They seem to keep everything battened down up there all the time, as do we, as high winds are expected from time to time.
Here in the south of Scotland winds were low 50s this morning, now barely 40, but it's decidedly wet. One of our sons drove right down the east coast to Kent this morning and said traffic and weather were both light.
It's all the makeshift poultry run covers people have had to put up hurriedly which seem the most vulnerable to me.
