Winds with gusts to 60 mph could lead to large waves over-topping some coasts, with possible flooding. Areas most at risk this evening are western coasts of England, Wales and Scotland and also the north coast of Northern Ireland.
Forecasters at the Met Office work closely with the Environment Agency and Scottish Environmental Protection Agency to provide early warnings and up-to-date advice in these situations.
David Rooke, head of flood defence at the Environment Agency, said; 'We will continue to monitor the situation along the coastline. Flood watches or warnings will be issued where appropriate, to give people as much notice as possible. High tides are expected for this weekend, so anyone out near the coast should be aware of any changes in weather conditions.'
People are advised to follow latest weather forecasts from the Met Office and see EA and SEPA websites for the latest flood information.
