It seems very likely that tomorrow will see significant flooding at Farlington Marshes with a high spring tide (predicted at 5m) combined with strong winds and low pressure. Under these conditions it is quite possible for the tide to not just break over the wall but to flood over. The high will be at 12:20, so setting off around the wall at anytime after early morning will be potentially very dangerous, you do not want to get caught at the Point in these conditions! There is also a very real risk that the wall could breach completely in which case the majority of the site will go under water, perhaps to several metres depth in places.
Please do not go down to the Marsh tomorrow and be aware that it is probable that the effect of the storm will also make access difficult for some time ahead.
