Typhoon ? !
On getting back from the office, I noticed the doorway to the apartment had a prominent sign informing me that there was a Typhoon Level 1 Warning.
Alas there seems to be no global standard for Typhoons, In Philippines the range is 1-5 which means "Get Ready"/"Prepare to possibly die". Hong Kong seems to have a little more granularity to this system with numbers from 1-10.
So I have reinterpreted the Typhoon warning to being in Filipino speak "A normal day - no worries."
We did get some good bangs of thunder, which seem to echo rather like your voice in a canyon off the multitude of sky-scrapers that adorn the HK sky-line.
In normal non BW light.
