The UK is bracing for 'disruptive snow' and plummeting temperatures as an Arctic blast brings the coldest night of the season so far. The Met Office recorded a low of -7.8C at Tulloch Bridge in the Highlands early Monday, marking the chilliest night of autumn.
Up to 20cm (8in) of snow could accumulate in the worst-affected areas, primarily on hills above 300 metres, with lower levels possibly seeing 5-10cm. Yellow warnings for snow, ice, and sleet are in place across parts of England, Wales, Scotland, and Northern Ireland through Tuesday and Wednesday.
The UK Health Security Agency has issued its first amber cold weather health alert of the season, warning of dangers to vulnerable people, including the elderly. Drivers are advised to pack winter essentials and allow extra time for journeys, as travel disruption is likely.
Temperatures are expected to remain several degrees below average for much of the week, with lows of -2C in London, -4C in Birmingham, and -7C further north. Widespread frost is anticipated as Arctic maritime air pushes across the country.
