Red 'risk to life' weather warning for South West and Wales as Beast from the East meets Storm Emma

Hundreds of drivers spent the night in their cars amid bitterly cold temperatures after becoming stranded on roads as heavy snow continues to cripple the UK's transport system.
Schools around the country were to be closed on Thursday as Britain braced for another day of sub-zero temperatures, icy blasts and "blizzard-like" conditions.
Many roads have been left impassable by drifts of snow, while trains and flights have also been hit by delays and cancellations as Storm Emma rolls in from the Atlantic and meets the chilly Siberian air of the so-called "Beast from the East".
