Hour-by-hour weekend weather forecast as snow and ice warning hits London

Heavy snow, sleet, and freezing rain could cause significant disruption, impacting travel, services, and safety.

Londoners are encouraged to avoid unnecessary travel, wear appropriate footwear to prevent slips, and check on vulnerable neighbours.

A band of rain is moving northeast, turning into snow on its northern edge.

While snow in London is expected to be short-lived, areas further north may see significant accumulations.

The weekend will also bring strong winds, increasing the risk of drifting snow and icy patches.

Temperatures will rise slightly by late Sunday before another cold snap early next week.

The warning highlights several potential risks, including:

• A small chance of power cuts and mobile phone service disruptions.
• The possibility of rural areas becoming isolated due to snow and ice.
• Risks of slips and falls on icy pavements, leading to injuries.
• Travel delays, with the potential for stranded vehicles and passengers.
• Disruption to rail and air travel, with cancellations and delays likely.
