Parts of the M4 and the old Severn Bridge have been closed due to strong winds, causing significant traffic disruption in Wales.

It comes as Storm Noa, which has arrived on the southern coasts of England and Wales as well as in northern France, was named by the French meteorological service.

The Met Office has issued a yellow weather warning for wind for these parts, with the possibility of large waves in coastal areas.

Why is the M4 closed?

Several stretches of the M4 were closed completely due to strong winds on Wednesday morning, causing severe disruption to travel into the afternoon.

The following areas were closed off:

  • M48 Severn Bridge both directions between J2 A466 Wye Valley Link Road (Chepstow) and J1 A403 (Aust)
  • Kenfig Bridge westbound from J37 A4229 (Pyle/Porthcawl) to J38 A48 (Margam)
  • M4 Briton Ferry Bridge, Port Talbot eastbound from J42 A483 (Swansea East/Briton Ferry) to J41 (Baglan/Pentyla)

Lanes are slowly reopening, but there is significant traffic.

Where are weather warnings in place?

The Met Office has a yellow warning for win in place along the coasts of southern Wales and England until 8pm on Wednesday.

Chief meteorologist, Matthew Lehnert, said: “Most places will see showers or longer spells of rain today but the impacts are most likely to come from strong winds. Gusts of 50-60mph are possible quite widely in the south-west, with up to 75mph in exposed coastal areas.

“Some disruption due to strong winds is expected in southern areas, particularly the south coast of Wales and south-west England. It will be a cool day with temperatures of 7-10ºC in the west, with 11-13ºC possible in the south-east, however it will feel colder in the strong winds.”

What is the latest weather forecast?

The Met Office said: “It will stay unsettled through the rest of the week, with sunshine and heavy showers for many tomorrow, with persistent rain in the south on Friday, before it becomes drier and brighter as we head through the weekend and more especially next week with temperatures starting to rise.”

Here is the latest daily forecast:


Rain in northern Scotland slowly clearing. Elsewhere, some sunshine but showers becoming more widespread, frequent and heavier. Very windy, especially across southern areas and parts of Northern Ireland, with severe gales in places. Distinctly chilly in the wind and rain.

Wednesday night

Rain or showers becoming increasingly confined to the central and some northern parts, with clearer spells developing further south. Strong winds in the west and south easing. Chilly again.


Further showers across many areas of the UK, again turning heavy at times. Becoming drier across some south-western regions, with the best of the sunshine here. Less cold, less windy.

Friday to Sunday

Rather cool again on Friday, with showers in the north and some rain moving east across southern areas. Drier over the weekend and brightest in the east, and feeling warmer.
