The UK has recorded its coldest night since March as temperatures turn noticeably colder this week - with snow, frost and ice forecast in some areas.
Temperatures dropped to -7C (19.4F) in Tulloch Bridge in the Highlands on Saturday night, the lowest since 20 March, according to the Met Office.
Storm Claudia also brought heavy rain across the southern England and Wales, with a major incident declared in Monmouth on Saturday after severe flooding.

Daytime temperatures in parts of the South early this week are forecast to be around 10C lower than we've had recently.
Met Office deputy chief meteorologist Dan Holley said high pressure to the northwest would "drive a cold northerly flow from the Arctic", bringing with it "much colder conditions than of late".
"There will be widespread frosts across the UK, with temperatures dipping as low as -7C in places next week, and daytime temperatures staying in single figures across the country," he added.
"Couple this with a brisk northerly wind, and there will be a marked wind chill. This will be a notable change in our weather after a prolonged spell of above-average temperatures."
Mr Holley also said "there will be a risk of wintry hazards, such as snow and ice".

The UK Health Security Agency has also issued a yellow cold weather alert from today until Friday for the East Midlands, West Midlands, North East, North West, and Yorkshire and The Humber.
It warns of a potential rise in deaths in over-65s and people with health conditions; an increased demand for healthcare services; and that vulnerable people could be at risk as some could find it hard to keep indoor temperatures at the recommended 18C.
