Freezing fog is forecast to drastically reduce visibility in parts of Somerset tomorrow morning.
The Met Office has issued a severe weather warning in the county, urging motorists to take extra care with visibility expected to fall well below 100m in some areas.
The yellow warning is in place from midnight until 11am tomorrow.
Fog is forecast to form at first in East Anglia tonight, before stretching over southern areas of the UK at first light tomorrow morning.
The Met Office said the fog formation will be caused by the combination of clear skies and light winds overnight, which will allow temperatures to fall quickly.
