Verifiability is a problem. I'm a little laxer than some, so if copyright
permitted I might
accept official government documents as sources. Probably not, in this
case, but maybe. But it's not going to render, anyway, which would make it
to those who know how to use overpass-turbo.
Maybe uMap is the way to go for this. Or a CSV file of co-ordinates fed
through a bit
of programming to produce a web page using Leaflet. Either way would give
map with pins which can display text such as risk level.
