The Met Office has issued fresh yellow weather warnings for snow and ice across Scotland from Monday evening until Tuesday noon, leading to the closure of over 70 schools. With temperatures dropping to -13C in the Highlands, further snow showers and icy conditions are expected. Authorities are urging caution for those traveling or walking outside, as road conditions remain difficult. Preparations are underway with gritting trucks stocked and ready to mitigate the impact of ongoing winter weather as commuters return to work.
