Rhybuddion gan y Swyddfa Dywydd ar gyfer: Newport

  1. Rhybudd melyn o eira

    O:
    1500 ar Iau 29 Ionawr
    Tan:
    1100 ar Gwe 30 Ionawr
    Diweddarwyd ar 29 Ionawr am 10:43 Mewn grym

    Warning

    Mae'r cynnwys hwn ar gael yn Saesneg yn unig.

    Showers during Thursday afternoon and evening are expected to fall increasingly as sleet, snow and hail. This may settle in places, especially from late afternoon and more especially on high ground. In addition, a more persistent spell of rain, sleet and and snow may affect the west and south of the yellow area during the early hours of Friday morning. Most areas are unlikely to see large amounts of snow but icy stretches are likely to form on untreated surfaces.

    The public should be aware of the risk of some travel disruption and difficult driving conditions.

    0700 ar Gwe 30 Ionawr
    Diweddarwyd ar 29 Ionawr am 14:40 Mewn grym

    Warning

    Mae'r cynnwys hwn ar gael yn Saesneg yn unig.

    Strong northwesterly winds are expected to develop across parts of South Wales and southwest England this evening, persisting overnight, before gradually easing tomorrow morning. Inland gusts are likely to widely reach 50-60 mph, with 70 mph possible along exposed coasts and over high ground.
    The public should be aware of the possibility of disruption to travel, with difficult driving conditions, particularly for high-sided vehicles.

  4. Rhybudd cynnar melyn o eira

    O:
    0015 ar Sul 1 Chwefror

    Alert

    Mae'r cynnwys hwn ar gael yn Saesneg yn unig.

    Further snow showers will affect parts of Scotland and Northern Ireland on Sunday leading to some locally large accumulations and the showers may spread along eastern and western coasts of England and Wales. The showers will be associated with strong winds so drifting and temporary blizzard conditions are possible as well as icy stretches. The public should be aware of the potential for disruption from these conditions.

    Snow showers are likely to continue to affect similar areas into Monday bringing further accumulations. Meanwhile, there is a risk of a more persistent spell of rain, sleet and snow affecting Wales, the Midlands and southwest England on Monday. This alert has therefore been extended into Monday and now covers these additional areas, but this is more uncertain and therefore further updates are likely in the coming days.

Allwedd

  • Coch: Gweithredwch
  • Ambr: Byddwch yn barod
