A yellow warning is currently in place for ice in London.

The Met Office has warned that ice is likley to cause difficult driving conditions over Tuesday night into Wednesday morning.

Londoners can expect injuries from falling on icy surfaces and there will likely be icy patches on untreated roads, pavements, and cycle paths.

But what exactly is this warning and what should you do? Here’s what you need to know.

What is a yellow warning for snow and ice?

For a variety of weather conditions, yellow alerts may be issued. Many are sent out when it's expected that the weather may have some low-level effects, such as travel delays in some areas.

The Met Office says the yellow warning for snow and ice means some untreated roads, pavements, and cycling paths may have some icy patches. In select locations, treacherous driving conditions might develop quickly due to intense sleet, snow, or hail showers that make roadways slick or even snow-covered.

The weather body also cautions against ignoring possible risks from falls and slips on slippery surfaces.

What should you do?

In addition to driving carefully, the Met Office advises putting together a winter kit for your car with a few necessary goods. This ensures that you're prepared in case you become stranded in chilly or icy weather. This could consist of an ice scraper and de-icer, a phone charger for the car, as well as warm clothing and blankets.

Other road users such as cyclists should keep a close eye on weather forecasts and warnings to avoid potential danger spots on their journey.

As wintry conditions prevail, people are asked to check on family members and friends who may be at risk to make sure they have access to warm meals and beverages.

Meanwhile, the UK Health Security Agency has advised people to maintain indoor temperatures in their houses at or above 18°C.
