Looks like it will remain a mystery (and can't be a 'desert-origin'
dust/rain event); very striking on the vehicles I saw - the fact that you
(Bernard) have had reports for yesterday (22nd) may point to something
very local, but if it is, then it affected a large area of south and SW
Bracknell.

Martin.


But there does appear to be dust in the cold air of the low west of Ireland

shows up best in black and white I think.
The most likely source must be Iceland as this is where the air mass
originates and would fit yr bill Martin.
The patchy nature of the rain wld easily lead to local deposition,
