Forecasters have warned more snow and ice is on the way in Wales. The Met Office has issued a new yellow alert covering a 12-hour period on Wednesday morning, November 20.

Today’s warning was earlier expanded to cover parts of Powys and Ceredigion as well a much of North Wales. A similar area is covered by the latest alert, though it extends further south to include Llandovery.

Wednesday’s warning comes into effect at midnight and runs until midday. The Met Office said: “Snow showers will develop during Tuesday night and through Wednesday morning. Some lying snow is likely, with 1-2 cm in places and a risk of up to 5cm over higher ground. Ice will readily form on untreated surfaces.”

Anglesey and northwest Gwynedd, including the Llŷn Peninsula, are expected to escape the worst of the conditions. So too is the North Wales coast. Coastal areas in south Gwynedd are in the firing line, however.

Driving conditions in the affected area may again be “dangerous” the forecaster warned. Some roads and railways may be affected and there’s likely to be icy patches on some untreated roads, pavements and cycle paths. Slips and falls are possible, added the Met Office.

Temperatures are expected to plunge today, reaching -4C by 5pm in parts of northeast Wales, such as Wrexham, Mold and Llangollen. Overnight lows of -5C are forecasted. It will be marginally warmer further west, with the mercury falling to -3C in Denbigh and Bala. Llangefni and Bangor is expected to fall to -2C, with the west Gwynedd coast perhaps dipping below zero.

In its Wales forecast, the Met Office said: “Dry and settled overnight, although becoming cold, particularly in rural parts, with a widespread frost likely. Scattered showers, wintry at times, filter into the west by the morning.

“A cold and frosty (Wednesday) morning with wintry showers in places, before turning drier and brighter later. Occasional sunny spells in the east, though remaining rather cloudy further west. Maximum temperature 8C.” Sign up for the North Wales Live newsletter sent twice daily to your inbox

  • Meet the aging hunters battling bears in rural Japan

    STORY: In rural Japan a gunshot rings out. A bear slumps in a cage."This brown bear got too close to a human community. It wasn't right here but over that way in the middle of the town and on the roads close by. In this kind of situation, we have no choice other than to trap them." Bears are making their way closer to homes, and putting people’s lives at risk. Keeping the townspeople safe often falls on the shoulders of a dwindling band of aging hunters, like 75-year-old Haruo Ikegami. "I'm often the first one that gets there when they're caught like this, and I always say, 'oh come on, you're already in there?' I can't bear it."Once a common sight among the trees, hunters like Ikegami are now older, and fewer in number than before. :: RUNNING OUT OF TIMEJapan’s population is both aging and shrinking.As of 2020, about 60% of gun license-holders, like Ikegami, are over 60. And in areas where bears roam, some residents wonder what will happen when these hunters can no longer do their job. In the town of Naie, Tatsuhito Yamagishi has accused the local government of taking hunters for granted."They say we should train new hunters, but there's nothing specific on how we should do this. Who's going to hold the training sessions and the workshops? In a few years' time when we (hunters) are all over 70 years old, will there even be anybody left who could teach people how to hunt bears, even if they wanted to?"Naie’s local government declined to comment on the dispute with Yamagishi, but said officials were taking steps to address the bear problem.Japan’s environment ministry says it subsidizes local governments to train officials and conduct bear drills.But the country’s reliance on recreational bear hunters could become unsustainable, according to the hunters themselves, officials, residents and experts Reuters spoke to. :: BOLDER BEARSBoth black and brown bears’ habitats have been expanding, in part because of depopulation in rural areas, experts say.Some believe this, and less managed farmland, may be making bears more daring.And the animals appear to be raising cubs closer to human settlements, causing them to fear people less than before.All this has contributed to an increase in human-bear incidents.In the twelve months through March 2024, 219 people were attacked. Six fatally. More than 9,000 black and brown bears were trapped and culled over that period, according to Japan’s environment ministry.84-year-old Katsuo Harada carries scars from over 20 years ago, when a bear sank its teeth into his skull.'It was like it was gnawing on a raw radish, scraping and crunching. I passed out at the sound and I don't know what happened beyond that."Harada is now part of a group that helps keep problematic wildlife at bay."I feel that I have to protect the people living here. Whenever I set a trap, you saw today there are four locations, I'm driven forwards by the thought that if I hadn't laid the traps, somebody could have been killed." One common way to trap bears is by using a large cage with bait, like a deer carcass, salmon or honey. The trap is designed so that the creature steps on a metal plate when it goes near the bait, triggering the door to close. The local authorities then make a call on what to do with the animal and may involve licensed hunters to kill it. The trapped bear is looked after and fed until it is culled.As an alternative solution, some companies are turning to technology.This “Monster Wolf” robot growls, barks and emits threats. Costing about $2,500, it is triggered by a sensor and powered by solar energy.It has shown some success, but Yamagishi explains that it takes years for humans to learn how to trap bears and insists their expertise will remain indispensable. :: DWINDLING FRONT LINEResponding to the increase in attacks, the Japanese government this year proposed relaxing rules around gun use to make it easier to shoot bears in urban areas.But hunters say it’s hard to find new recruits because the job is expensive, unappealing, and exhausting.Some get 8,000 yen, or about $50 from local governments for a bear cull. This might cover expenses and fuel, Ikegami says, but little else. A system is needed, they suggest, where hunters are paid enough to support a family. Because if the younger generation doesn’t take up the torch, the last line of defence will soon be gone.
