12m high tide today in Jersey is higher than predicted
High water (17/10/2012) at 0814 was predicted at 11.67m.
With low pressure of 998mb and a Force 6 SW wind the actual height of the tide was pushed up to 12m.
The National Oceanography centre tidal gauge for St Helier shows the increase as around .5m.
Previmer surface sea levels data also shows how the wind and low pressure led to the storm surge.
Sea levels remained higher well after the high tide had passed.
Downside is that the low tides are not likely to pull down so far as a result.
