As of this morning, the Thames between Putney Bridge and Teddington Weir is on Flood Watch. However, it looks as though the Thames Barrier has been closed, as the water level is nearly a metre lower at Charlton, upstream of the barrier, than at Silvertown downstream. This is evidently to create more space for the water pouring over Teddington Weir, which has raised the level at Richmond considerably (1.3m higher than normal currently). High tide at Brentford is due at 16:08, but I think that's a bit academic today, as we seem to have a freshwater tide coming downstream!
