It's been snowing in Tideswell all day with the temp between -2 and -4 and with
a Force 3-5 wind. The snow has no liquid water content and the action of the
wind has broken it up into a very fine powder which has drifted very readily in
the wind this afternoon and evening. There's now nothing that can be described
as a 'level depth' anywhere. Some areas have been blown almost completely bare
while in others it's getting close to a metre deep. This evening I've
guesstimated 15cm but, come daylight tomorrow, I suspect that I might increase
that a bit. Nevertheless, there'll still be quite a bit of a guess in there.

The rainfall equivalent is an even more difficult matter. In a situation like
this the rain gauge is irrelevant. Also, there's no representative bit of snow
on the ground that I can 'capture' and melt. About the best I can think of is
to use whatever I decide as a representative depth of fresh snow and use a 10:1
ratio. Does anyone know if there's an 'official' way of dealing with this....
