Why is seemingly the whole country reporting only a trace of

It's because humans are now largely redundant in the system.

That's progress!

Even a manual rain gauge is of no use in the sort of conditions we
have here this morning. The funnel fills to the brim with falling
snow and drifting snow then anything further just blows off.
There's no 'level' snow from which to calculate a probable rainfall
equivalent. This morning I simply gave a sensible estimate based on
the amount of precipitation that I observed. It might be an
accurate estimate or it may not but it's the best I can do. The
last tip of the AWS bucket was at 1540z on 27th Feb. Some sunshine
that afternoon had caused a little melting of the snow in the
funnel.

I had 2.6 mm in my 5 inch funnel when I melted the snow yesterday.
Difficult to judge level snow but it was at least 10 cm in my garden
which could equate with about 8 mm. (1 foot snow=1 inch rain in old
money). Today has been hopeless with the gale force wind. Very
little in the funnel. So measuring precipitation in these conditions
is really a busted flush.

I agree. In these conditions, the best you can do is give a sensible
estimate.
