The rising Thames

I arrived at work this morning to find a crew of hard-working lads out sandbagging all entrances to the office in Staines. As I left tonight the sandbag walls had grown and I had to virtually climb over them to get out. Staines has a flood warning current but I think this is precautionary. The Thames at Runnymede was a few inches higher tonight. Reports indicate that the Thames level should peak tomorrow.
