Haha ... and there I was filming the rest of it out in the flooded streets. I was watching this from the outside.

Stupid question probably: what on earth is black rain?

@weeardguy I think i found out what it is, there is a signal system in hong kong for flood warnings and heavy rain, 'Black' signifies imminent flooding, so 'black rain' is the flood rains.

That sounds logical ;) Thanks.
