Yes was 3/4ft drifts here, but thats some drift that 4wd posted.

Like you say, has to be over 5ft.

Any measurements 4wd?

I really couldn't say, truth is the single track road is in something of a dip, and the piles of snow are pushed up by a digger but they are about 6 feet in places.

This is a good 24 hours after the snow fall ended and it has been thawing so will have sunk down considerably.

There would be some spots with far deeper snow than this place elsewhere on the moors.

Any who know the area will be aware there are expansive plateau-like areas of open heather over which snow can drift until it drops into a small valley - then on that edge you can get very deep snow indeed although measuring on a steep slope is problematic.

A more revealing statistic is that my weather station has counted 36mm of rain this month and all but 3 or 4mm of that is from snow melt.

Plus since it was very windy and snow was blowing almost horizontally a great deal will not have been counted.

So a conservative estimate is that we had about 40mm of precipitation which fell as snow even here in the valley. An accepted approximate conversion is 1 to 10 which suggests 40cm of snow fell, mostly in the space of 12 hours between 6pm 3rd April and 6am 4th April.

Precipitation can sometimes be 50% greater over the high ground than here in the relatively sheltered valley - especially in a scenario like this storm where moisture laden air from the sea is dumping onto the first high ground it meets.
