Yellow weather warnings have been issued for severe gales and heavy rain - but Yorkshire should escape the worst of the storm.
Winds of up to 70mph are expected in exposed coastal locations of the UK and further downpours are also due, with the Met Office adding 15-25mm is likely to fall in Wales and south-west England, and up to 40-60mm over some hills.
The north west of England is expected to be badly affected, so some parts of West Yorkshire could also see heavy rain as well as high winds.
A yellow weather warning in place for the strong gales covers all of Yorkshire.
The warnings are in place until midday on December 27. It means there is a possibility of travel being affected, roads closed and damage to buildings.
Parts of the country are already sodden after recent wet weather and flooding, with residents in more than 1,300 properties along the River Great Ouse in Bedfordshire advised to leave their homes as water levels rose on Christmas Day.
Bella, which follows relatively calm and cold conditions across the UK on Friday and early morning snowfall recorded in some areas, has led to the Met Office issuing an amber wind warning, which warns travel could be disrupted, for parts of south Wales and across southern England on Saturday.
