A fresh yellow wind warning has been issued by the Met Office for Storm Austen, which is expected to affect southern England and Wales overnight on Thursday and throughout Friday.
Forecasters predict westerly winds turning northwesterly, with gusts generally reaching 50 to 60 mph.
Coastal locations and other exposed areas may experience gusts of 70 mph or higher.
Sussex already had one warning in force for the southern part of the county between midnight and 5pm on Friday, October 23.
A further warning was issued on Thursday morning for the remainder of Sussex, taking effect from 10am until 9pm.
Although conditions in the newly covered area were not expected to be as severe as those further south and west, inland gales could occur on Friday, with gusts of about 45 to 55 mph.
Periods of heavy rain in some locations, alongside trees retaining their foliage, increase the possibility of power cuts and disruption to transport services.
Temporary interruptions to electricity supply and delays to transport networks were also considered possible.
Storm Austen is the first named storm of 2026/27.
The Met Office announced the new list in September after considering more than 40,000 suggestions submitted by the public.
Those proposals included names honouring children, pets and fictional characters such as Shaun the Sheep, as well as tributes to deceased relatives and pioneers in meteorology.
The naming scheme is operated with Met Éireann in Ireland and KNMI in the Netherlands.
New lists are introduced each September to coincide with the start of the autumn storm season.
Storms are listed alphabetically, with the letters Q, U, X, Y and Z excluded.
Austen was selected by Met Éireann to recognise Austen Nagle, the inaugural director of the Irish Meteorological Service, during its 90th anniversary year.
Under the system, a storm receives a name when forecasts indicate that it is likely to have a medium or high impact in the UK, Ireland or the Netherlands.
Wind is the main factor, although notable impacts from rain or snow can also lead to a storm being named.
