    Fascinating talks and demos. Obviously the best was the LLM to Shipping Forecast generator.

  2. Storm Ingrid set to batter South West Wales with heavy rain, strong winds and flooding risk

    Yellow warnings in place for South Wales

    The Met Office has issued Yellow weather warnings for rain across South Wales, including Carmarthenshire, Pembrokeshire, Swansea and Neath Port Talbot, as Storm Ingrid brings another spell of wet and windy weather to the region.

    Forecasters say the storm — named by the Portuguese national weather service — will sweep in from the southwest early on Friday, with conditions expected to worsen through the day and into Saturday morning.

    “Potential for disruption” across the region

    Met Office Chief Forecaster Neil Armstrong said the system could cause problems even though rainfall totals in Wales won’t reach the extreme levels expected in parts of Scotland.

    “While rainfall totals in Northern Ireland, south Wales and parts of the southwest of England won’t reach those that we’ll see in parts of Scotland, there’s still a potential for some disruption, particularly for travel.”

    The Met Office says the warnings highlight the risk of fast‑flowing or deep floodwater, difficult driving conditions and the possibility of some communities being temporarily cut off.

    Heavy rain falling on already saturated ground

    Storm Ingrid is expected to bring more than 20mm of rain for some areas, falling on ground already soaked by weeks of unsettled weather. Forecasters warn that even modest rainfall could lead to surface flooding, swollen rivers and blocked routes.

    Along the coast, large waves and strong gusts are likely, with winds of 45–50mph inland and peaks of up to 60mph possible in exposed areas.

    Friday looks worst for South West Wales

    The Met Office says the worst of the weather for Wales will arrive on Friday, with rain pushing in from the southwest and lingering into Saturday morning before easing.

    Scotland will continue to see the heaviest rainfall, with some high‑ground areas expected to exceed 100mm, but South West Wales remains firmly in the zone for disruption.

    More unsettled weather to follow

    Low pressure will continue to dominate through the weekend, bringing further spells of rain and wind. Looking ahead to next week, the Met Office says there is still uncertainty, but wintry conditions are possible in parts of the UK, especially further north and east.

  4. Swansea escapes Storm Goretti snow – but Wales still hit by thundersnow, travel chaos and power cuts

    While South West Wales’ main urban centres saw rain instead of the heavy snow forecast, conditions elsewhere deteriorated sharply, with parts of Pembrokeshire even experiencing rare thundersnow as schools shut, rail lines suspended, mountain roads closed and hundreds of homes left without power.

    Mountain routes shut as blizzards hit higher ground

    The Bwlch mountain road (A4107) was closed at 7pm on Thursday after conditions became unsafe. The joint decision by Neath Port Talbot, Bridgend and Rhondda Cynon Taf councils followed reports of drifting snow and falling temperatures. The route reopened shortly after 8am today.

    Pembrokeshire saw some of the worst conditions, with heavy snow, sleet and strong winds creating hazardous driving on higher ground. The B4329 between Haverfordwest and Cardigan, which crosses the Preseli Hills, remained closed for long periods as blizzards hit the route.

    Issues were also reported on the B4313 between Fishguard and Narberth, where drifting snow made conditions treacherous across the northern foothills.

    Further south, the A478 from Clunderwen to Cardigan saw significant snow in places, with drivers warned to avoid higher ground as accumulations built up.

    Council teams worked through the night to clear fallen trees, deal with surface water flooding and keep primary routes open.

    Thundersnow caught on camera in Pembrokeshire

    A dramatic burst of thundersnow was captured in Pembrokeshire overnight, with lightning illuminating heavy snowfall as Storm Goretti swept across the county.

    Local resident Harvey Harbour filmed the moment and shared it on X, showing bright flashes lighting up the sky as snow fell across the area.

    What is thundersnow?

    Thundersnow is a rare weather phenomenon where a thunderstorm produces snow instead of rain.

    It happens when a strong, unstable weather system forms above very cold air at ground level. The storm still generates lightning and thunder, but the precipitation falls as snow.

    The lightning often appears brighter because it reflects off the snowflakes, while the thunder sounds quieter because the snow absorbs the sound.

    Thundersnow can bring sudden heavy downpours of snow, reduced visibility and rapidly worsening road conditions.

    Rail disruption continues across Wales

    Transport for Wales services remain heavily affected, with suspensions and reduced timetables on several lines following snow, ice and fallen trees.

    Routes impacted include:

    • Craven Arms to Swansea (Heart of Wales Line)
    • West of Carmarthen
    • Maesteg to Ebbw
    • Wrexham to Bidston
    • Llandudno Junction to Blaenau Ffestiniog

    CrossCountry services between Cardiff and Birmingham are not running, and passengers are being urged to check before travelling.

    Your earlier Swansea Bay News reporting highlighted “do not travel” warnings issued yesterday as rail operators shut lines ahead of the storm.

    Schools shut and power cuts reported

    Across Wales, at least 150 schools are closed today, with Powys, Blaenau Gwent and Wrexham among the worst affected.

    Around 600 homes were without power this morning, with further outages reported in north and mid Wales. Pembrokeshire also saw power cuts around Clunderwen and Bridell, alongside burst water mains in Haverfordwest.

    Emergency services across Ceredigion and Powys reported “numerous incidents” overnight, with police urging people to avoid all but essential travel.

    Swansea spared – but warnings remain in force

    Despite fears of thundersnow and blizzard conditions reaching Swansea Bay, the city avoided the worst of the storm, with rain and sleet falling instead of snow.

    However, Amber and Yellow warnings for snow, rain and wind remain in place across much of Wales, and forecasters say conditions may continue to change through the day.

    Bridgend Council said all routes in the county borough remain open after crews dealt with fallen trees and blocked drains overnight.

    What happens next

    The Met Office says Storm Goretti remains a “multi‑hazard event”, with snow, strong winds and heavy rain still expected to bring disruption in parts of Wales.

    Gusts of up to 70mph are forecast along the south coast, while higher ground in mid and north Wales may see further snow and ice as temperatures fluctuate.

    Swansea Bay News will continue to update readers as the situation develops.

  6. Bloody keep changing their minds about whether they're going to make it rain when I'm at the next week. Bastards. Sort yer scheduling out!

  7. Is anyone else in the west of the UK keeping a worried eye on the weather? I'm seeing a bigger than usual difference between wind speed and gust speed in the met office forecast and am not currently experiencing the forecasted gusts. Looks like it will be coming from the north during the peak too, which is unusual. Interested to hear anyone else's thoughts. #UK #weather #metoffice #southwest #westcountry #wales #gloucestershire #wiltshire #somerset #devon #dorset #cornwall #Severn #bristol

  8. ⚠️🧊 In addition to the snow warning in effect for tomorrow, #MetOffice have also issued a Yellow Warning for Ice that covers eastern parts of #Flintshire & #Wrexham. This new warning is in effect Tue evening until 10am tomorrow. There is a concern of icy patches forming on untreated surfaces.

  9. 🌧️ #MetOffice have issued a Yellow Warning for Rain. Some parts of #Conwy, #Denbighshire and #Flintshire can expect some heavy showers 4am-10am Sunday.

  10. ⚠️ #MetOffice have issued a Yellow Warning for Thunderstorms across #Conwy, #Denbighshire, #Flintshire, #Gwynedd, and #Wrexham, effective until 9pm this evening. Some may see sudden downpours which could bring 20-40 mm of rainfall in a short period of time. While not everyone will see rain, those who do are at risk of some localised flooding. Because of this risk, #NaturalResourcesWales have also issued a Yellow Warning for risk of flooding.

  11. 🌬️#MetOffice have issued a Yellow Warning for Wind, 8am-10pm Sat, for #Anglesey, #Conwy, #Denbighshire, #Flintshire and #Gwynedd. A deep area of low pressure, will bring a spell of very windy weather to parts of western #Wales this weekend. Gusts of 50 mph are expected quite widely on Saturday, while some exposed spots, particularly on the coast, will see 60 to 70 mph gusts with large waves also likely.

  12. ⚠️❄️ #MetOffice have issued an AMBER Warning for Snow & Ice in parts of #Conwy, #Denbighshire, #Flintshire and #Wrexham, 8am-3pm Thurs. Over high ground, 10-15cm snow is expected - possibly 20-25cm above 200m. Strong winds may lead to drifting. Also risk of freezing rain.

    Lower areas may get 2-5cm, but not everywhere. This may fall as sleet or rain at times. As a result, Met Office have issued a Yellow Warning for Snow for the entire region, in effect between 6am Thurs and 6am Fri.

  14. It’s remarkable how the Met Office predicted the extreme weather from Storm Ciarán so far in advance. Before the low pressure system it developed from was anything special.

    I highly recommend subscribing to the Met Office YouTube channel and watching their weekly Deep Dive and 10-Day Trend videos. I watch every video they put out 😊

  15. One story we all think we're in is re-enforced every day. And it looks like endless conflict and drama.

    You know there certainly are some hours to just survive. But that's no way to live a whole life. Or make the difference.

    So, if you're a leader, I'm going to suggest you go find the people who can unlock some world-changing perspective.
