The Met Office has extended a 'danger to life' warning, expanding it to a wider area south of the UK and and warning it will hit worst overnight as high winds usher in the arrival of ferocious Storm Atiyah.
The yellow severe weather warning for today and tomorrow has now been extended overnight.
Manchester has now no longer included in the warning, which now covers more of Wales as the high gusts are forecast to hit further south and west.
The wind warning is now in force overnight, from 6pm today until 9am tomorrow as the national forecaster warns Brits to expect disruption to travel and huge waves for coastal communities.
Met Office meteorologist Luke Miall said the warning now extends overnight, and warns commuters and parents on the school run that the winds could cause travel disruption as it remains in force until 9am tomorrow.
Mr Miall said the warning has moved to cover south west of England and much of Wales, with winds speeds of around 50mph predicted inland, and up to 75mph in coastal areas.
The winds and rain are expected to hit hardest in the small hours of tomorrow morning and could bring "squally" conditions once commuters are on the move on Monday morning, he added.
The bitter weather could cause trees to fall and structural damage that could cause problems on the roads and railways tomorrow morning, he advised.
"There could be some disruption through to tomorrow morning for commuters as the warning is in force until 9am.
"So people up early and doing the school run likely need to be wary of some disruption tomorrow morning."
The Met Office had earlier issued two separate 18-hour yellow weather warnings for wind today and tomorrow, bringing strong gales in the south-west region.
The forecaster is warning that very strong winds are expected during Sunday evening and overnight, then a fresh yellow warning will also cover Scotland on Tuesday, as forecasts predict heavy rain.
Coastal regions covering Wales, south-west England and north-wet England are expected to see large waves up to 40ft offshore, whereas Scotland's west coast will see 28ft waves.
Britons are warned to be aware of any loose items or structures as strong winds could knock over Christmas lights or inflatable decorations from buildings.
