The expedition to the roof of a 35 story apartment building in Singapore's heartlands resulted in some nice images. The light was bad, however, as the second tropical storm for the day rolled in. I was not brave enough to try to photograph the lightening!
Here is a part of the storm.
To give this some scale, the hills in the distance are, in fact, in Malaysia. Those with a keen eye may be able to see the Straights of Johor in there too.
