The sky is black. →[More:]Apparently there's a huge fire in Stratford, and the sky over Canary Wharf is black as night with smoke.

Of course, this means I'm unlikely to get home at my normal time, as disruption to travel is likely to be intensive, Stratford is a major hub for overland and Underground trains and I have to change trains there. I know it's only lunchtime, but I'm already thinking about the journey home.
