The Met Office said: “Storm Evert will bring very strong winds to southwest England, perhaps causing damage to infrastructure and leading to travel disruption.” Amber and yellow weather warnings have been issued, with the Met Office warning that a “danger to life” could be posed by flying debris and enormous waves.
The Met Office is warning of a range of possible impacts from the winds, which could reach gust strength of 75mph (120km/h).
The amber warning, which covers the southwest of England, blanketing Cornwall and the Isles of Scilly, is in place from 9pm on Thursday to 7am on Friday.
The Met Office has warned that damage to buildings is “probable”, with “tiles blown from roofs… there may also be some fallen trees”.
The warning also issues caution over travel, with “road, rail, air and ferry” services likely to be affected.
The warning states: “There is a good chance that power cuts may occur, with the potential to affect other services, such as mobile phone coverage.”
And issuing a stern safety warning, the Met Office said: “Flying debris is likely and could lead to injuries or danger to life.
“Injuries and danger to life are likely from large waves and beach material being thrown onto coastal roads, sea fronts and properties,” it said.
A more widespread – though less severe – yellow warning has also been issued by the Met Office, spanning the southeast, wrapping around the south across Brighton and spreading up the east to Norwich.
These yellow warnings are in place between 8pm on Thursday evening to 6pm on Friday.
The Met Office said the “windy weather on Friday may lead to some travel disruption”.
Short-term power loss is possible in some areas, and fallen trees remain a threat.
The Met Office has advised everyone under the warnings to take extra care when travelling in these conditions.
Storm Evert is the seventh named storm for the 2020/2021 season.
A storm is named when it has the potential to cause an amber or red weather warning, to allow ease of communication between weather agencies and the public.
When the criteria for naming a storm are met, either the Met Office, Met Éireann or KNMI can name a storm.
They then let the public, government and the responder community and the media know to ensure a cohesive approach.
