The destructive weather pattern formed in the Atlantic has been named Storm Brian and will smash into South West England on Saturday and bring strong winds to Gloucestershire.
There could be disruption on land, sea and air as Brian moves across England and Wales with gusts of up to 50mph battering Gloucestershire.
The Met Office has issued a yellow weather warning for Saturday from 4am, saying a swathe of strong winds will sweep across southwestern areas.
Coastal areas could see gusts of up to 70mph which, combined with high tides, could create dangerous conditions.
The Met Office says some transport disruption is likely across the warning area, with delays to road, rail, air and ferry transport.
Short term loss of power and other services is also possible.
The weather system was named Storm Brian by officials at Met Eireann (The Irish Met Office) and has been adapted in the UK.
The last storm, in September, was named Aileen.
What is a weather bomb?
A 'weather bomb' is an unofficial term for a low pressure system whose central pressure falls 24 millibars in 24 hours in a process known as explosive cyclogenesis.
Rapid acceleration of air caused by the jet stream high up in the atmosphere can remove air from the column, reducing its weight so causing pressure to fall at sea level.
This in turn sucks in air which converges from surrounding regions resulting in faster and faster rotation of the circulation, in the same way that ice skaters spin faster by drawing their arms in.
The resulting winds peak over a period of a few hours and can be strong enough to bring down trees and cause structural damage.
