I'm in Exeter, and the River Exe was scarily high a few days ago. The city was last flooded badly in 1960, after which the current flood defences were built. They work well for my part of the city, but on either side of the defences there was bad flooding. Both main line train lines out of Exeter towards London were closed, the Waterloo line due to a landslip near Yeovil, and the Bristol-Paddington line because of severe flooding just outside the main station. The flood water had receded now, but the damage to the track bed will still take several days to fix.
It worries me that flooding this bad has happened so early in the season. Thankfully the next few days should stay dry, but the ground may remain sodden for much longer, so any further heavy rain may be disastrous.
