Storm Ciara was named by the Met Office on Wednesday and is moving eastwards across the UK and Ireland.
Alex Burkill, a meteorologist at the Met Office, said the wet and windy weather is “the prelude, if you will, to what is Storm Ciara”.
He said the most pressing of the Met Office warnings is the amber wind warning.
“That’s where we’re likely to see significant impacts from the wind. We’re taking some damage to property, flying debris, and that could bring the risk of injury to people, as well as just the usual things such as power outages and disruption to travel,” he said.
“It is worth bearing in mind that the strong winds on Sunday are going to be very widespread so it’s across the whole of the UK where we’re going to see very strong winds, so the impact will be widespread.”
Burkill said gusts of 70-80mph were expected, “and it could be a little bit stronger than that in some exposed spots”.
