The United Kingdom is preparing for another spell of severe winter weather as Storm Goretti approaches, prompting the Met Office to issue new and extended warnings for snow and ice across much of the country.

An Arctic air mass already gripping Britain has driven temperatures to their lowest levels of the winter so far, and forecasters say the incoming storm is set to intensify hazardous conditions from Thursday into Friday.

Snow and ice warnings are in force across Scotland, Northern Ireland, Wales and large parts of England, with northern and western regions expected to be hardest hit.

Forecasters warn that snowfall will combine with freezing temperatures to create dangerous ice, particularly on untreated roads and pavements.

In higher elevations, especially in northern Scotland and parts of Wales, accumulations could be significant.

The deteriorating weather has already disrupted daily life, with hundreds of schools closed and widespread transport problems reported.

Rail services have faced delays and cancellations, flights have been disrupted at several regional airports, and motorists have been urged to avoid unnecessary travel as conditions worsen.

Storm Goretti, named by Météo-France, is forecast to move eastwards across the UK, bringing a mix of heavy snow, strong winds and periods of rain.

Meteorologists have described the system as a multi-hazard event, with the potential for blizzard-like conditions in some areas, reduced visibility and drifting snow.

Authorities are urging the public to monitor forecasts closely and take precautions, particularly those in rural or elevated areas.

Health officials have also warned that prolonged cold poses increased risks to vulnerable people, as the country faces another prolonged period of wintry weather.
