Not much more to say than that.
Some massive travel disruptions out there this morning for ALL forms of transport, so make sure you check Twitter, TfL, or your train service provider before heading out into the misery of the rain.
Driving? You don’t escape either. Plenty of flooded roads etc.
If you’re on Twitter, TfL are piloting Undergournd alerts via Twitter DM. You chose which lines you are interested in and you get a DM any time there’s a problem. Not all lines are included but happily the Overground is.
Conversely the cycle paths are moving well, with no signs of overcrowding. A little bit of surface flooding in Burgess Park and around Tooley Street near the London Bridge Station works, but otherwise clear.
Fantastic to know 
And maybe some are even washed clean of debris for once too.
