The British Isles were hit by Storm Brian on Saturday, causing high Atlantic seas and some flooding, though disruptions were less than predicted.
Gust up 78mph were recorded on the northwest coast of Wales.
A yellow weather warning remain in place until midnight on Saturday.
"There has been some travel disruption and some trees down. We have also seen coastal impacts, with waves breaking over sea walls," forecaster Luke Miall said.
Ireland suffered 60mph winds, forcing some local roads to close. In Limerick, the River Shannon overflowed, while water threatened flood defences in Galway City.
"The rainfall is not finished but the extent of damage, flooding and disruption has been limited and in line with expectations for this type of Atlantic storm," Sean Hogan, chair of the emergency group, said.
The second named storm of the season, caused by a "weather bomb" of low pressure in the Atlantic Ocean, may also cause flooding, it is feared. South-westerly areas will be worst affected.
"If you don't need to be at the coast the best advice will be not to be there," he said," Met Office meteorologist Craig Snell warned.
"We are concerned that there could be some flooding at the immediate coast but even without flooding there will be some very high waves. The best bet will be to stay safe and stay away."
The Environment Agency has issued 42 flood alerts. "Teams are on the ground, checking defences and taking precautionary action to close tidal gates and put up temporary barriers," said Agency spokesman Ben Lukey.
"We're working with the Met Office and local authorities and are ready to respond as necessary. We urge people to stay safe along the coast and warn against putting yourself in unnecessary danger by taking 'storm selfies' or driving through flood water - just 30cm is enough to move your car."
Train services are likely to be disrupted, National Rail warned on Friday. "Fallen trees and other debris may temporarily block railway lines and damage overhead wires," a spokesman said.
"Speed restrictions may be imposed in the worst affected areas for safety reasons, which may delay your journey."
Brian follows Storm Ophelia, which battered much of Ireland and Northern Ireland on Monday. Three people were killed when the ex-tropical storm toppled trees and caused widespread damage, leaving thousands without power.
The Irish Met Office has issued an orange warning for wind across the country's south from 6am as Brian approaches. People across the UK and Ireland were warned against taking dangerous "storm selfies".
