The bus operator has now confirmed that all services are back running, however a number remain diverted due to disruption casued by Storm Arwen and the snow.
A spokesperson for First said: “Unfortunately, due to the inclement weather and road conditions, we are unable to operate a normal service.
“We apologise for any further inconvenience caused.
“Diversions will generally be both directions unless otherwise stated.
