Calm amid the storm
Take the umbrella with you this evening (picture is from 16:48) the general movement is from the NW to SW. That’s HK and Kowloon in the hole in the middle.
I am regularly geekcited by the amount of data that HKO provides in such a short time frame (not real time, but usably rapidly).
The radar maps (http://www.hko.gov.hk/wxinfo/radars/radar.htm) are critical to plan your forays into the wet world, the lightning maps (http://www.hko.gov.hk/wxinfo/llis/gm_index.htm) allow you to see how close you were to annihilation (over 3,000 ground to air strikes in the SAR today already). Not to mention the tide maps for when you are planning on being on the beach.
