GALE force winds are expected to cause widespread disruption as Storm Brian batters Britain and Ireland, less than a week after ex-hurricane Ophelia wreaked havoc.

Winds of 60mph have struck the Welsh coast and gusts are set to reach speeds of 70mph today (Saturday).

Forecasters have warned of the potential for power cuts, flooding and delays to transport, as families begin their half-term holidays.

The Met Office has issued a yellow weather warning for winds across a swathe of Britain, including Wales and southern England up to the Midlands, which will remain in place until midnight.

Strong winds had already hit southern and south-western parts of Ireland this morning.

Met Office forecaster Craig Snell said: “Unfortunately across Ireland it’s the areas that were worst-hit by Ophelia seeing the worst effects of Brian as well.”

People have been advised to stay away from exposed coastal areas and urged not to take so-called “storm selfies” as high tides and a storm surge create dangerous conditions along some coasts.

National Rail warned the stormy weather could impact on train services, with emergency speed restrictions imposed on most of the routes in Wales.

A spokesman said: “Fallen trees and other debris may temporarily block railway lines and damage overhead wires.

“Speed restrictions may be imposed in the worst-affected areas for safety reasons, which may delay your journey.”

Drivers were also urged to take extra care on the roads during high winds, as vehicle recovery and insurance firm the AA reminded motorists that surface spray, reduced visibility and potential flooding remained high risks.

The Energy Networks Association, representing the UK’s energy infrastructure, said residents could call the free 105 advice telephone number in case of damage to local network and power supplies.

Storm Brian is the result of a “weather bomb” of low pressure in the Atlantic Ocean.

It follows Storm Aileen, the first UK-named storm of the season, which left thousands of homes without power last month.
