Many holidaymakers at one of the UK’s biggest campsites have left early due to poor weather.

Shell Island in Llanbedr, Gwynedd, had been exposed to strong winds which have caused damage even before Storm Lilian hits.

The site said 70 per cent of visitors had packed up and gone, which Richard Workman, one of its directors, said had scuppered hopes for a bumper bank holiday weekend.

The Met Office issued a yellow weather warning for strong winds affecting parts of north Wales.

Despite the warning affecting only north Wales, a New Order gig in Cardiff due to take place on Thursday evening was cancelled on health and safety grounds.

The poor weather has caused travel disruptions with the M48 Severn Bridge closed between J2 A466 Wye Valley Link Road (Chepstow) and J1 A403 (Aust) due to strong winds.

The A55 Britannia Bridge between J9 A487 (Treborth) and J8 A5 (Llanfair PG) was closed to high-sided vehicles, motorcycles, bikes and caravans.

There are 14 flood alerts along the coast.
