Three different maps for each day, most likely the one you would be interested in is the first one FL000 to FL200, surface to 20000 ft. Black is no fly zone.

I’ve just been looking at the latest ones posted here:

Met Office: Volcanic Ash Advisory Centres

Same site, different sort of maps.

Those clever chaps at the Met Office just added another colour on the five day forecast map so now you have three different zones of ash levels.
