Has the Thames barrier been raised?


Its of no flooding consequence, just a rare meteorological induced effect.
The west coast tide gauges are picking it up now, but meteorologically
don't know its origins. Perhaps started off Scandinavia as that trough,
then just North Sea bathynmetric funnelling effect and enhanced later on
by Cape/Latent Heat instability over East anglia.
Anyone know of any live feed web cams , birdwatchers? over Essex/Kent
mudflats , .5m drop and rise over a short period would look impressive.
