Temperatures are forecast to plunge in London in the coming days with a predicted “snow bomb” hitting the UK.
The Met Office has said snowfall could hit hills and mountains in Scotland, Northern Ireland, northern England, and possibly North Wales in what it a "widespread wintry spell" next week.
Bitter conditions are expected to move south as the week progresses.
But currently, according to forecasters, only sleet is forecast to hit London - but this could change.
Sleet will fall in the early hours of Thursday as temperatures plummet to 3C, according to BBC weather.
Temperatures are to fall from Sunday as the heavy rainfall from Storm Claudia moves away.
Lows of 5C are forecast in the capital on Sunday, before falling to 2C on Monday and Tuesday and 1C on Wednesday, the Met Office has said.
The wintry weather follows widespread disruption brought by Claudia on Friday, with a month’s worth of rain predicted for some areas.
Amber warnings for "persistent and heavy" rain come into force from noon on Friday until midnight and cover parts of Wales, the Midlands, the South West, the South East, and East of England, and have been extended into parts of northern England.
Some places could have 80mm of rain in England, while part of Wales may be hit by 100-150mm on the higher ground, or 50-75mm generally across the region, the Met Office warning says.
