Storm cloud over Vancouver

This morning was chilly and sunny. I decided to bike to work from North Van, across the Lions Gate bridge and through Downtown busy streets, towards Commercial Drive area. I had a few stops to put jacket on and take jacket off. But when over the Dunsmuir Viaduct, looking south across from Science World I saw this massive black cloud covering Vancouver.
Of course, one more stop to take a picture. After all, it was a 53 minutes commute.
