Storm Eunice’s ferocious 100mph winds are set to slam into the country today - below you can check when you can expect to feel its fury.
Two rare red warnings have been put in place by the Met Office for the south west and south east, with millions of Brits preparing to batten down the hatches.
People living in those areas can expect the brunt of the storm - described as the worst in 30 years - but it will also sweep over other regions of the country over the course of the day.
Amber warnings for wind and yellow warnings for snow are also in place as the country braces for the worst.
Below is when you can expect Eunice to pay a visit to your area - and how severe the conditions will be.
