Fate and weathering facts observed/reported

Worthing beach was shut to allow heavy machinery to remove the timber which has come ashore. Planks and bundles of timber are reported to be several feet deep on the tide line. West Sussex County Council has also expressed concerns that the sea could throw the timber against shingle banks and groynes, causing flood defence damage. West Sussex County Council has issued an urgent plea to mariners, windsurfers and canoeists because of concerns that the floating wood could cause a serious accident.
