The Met Office has issued severe weather warnings for wind and rain for all of England and Wales for Monday, warning people to be prepared.
However, chief forecaster Eddy Carroll said the storm was not guaranteed to hit the British mainland and could pass through the English Channel:

This storm doesn't exist at the moment, but our forecasts models predict it is likely to develop in the west Atlantic on Saturday.
Then it's likely to rapidly intensify just west of the UK late on Sunday before tracking across England and Wales early on Monday.
There is still a chance this storm may take a more southerly track and miss the UK, bringing impacts elsewhere in northern Europe, but people should be aware there is a risk of severe weather and significant disruption.
