If you had outdoor plans for this weekend, you may want to rethink them.
Hurricane Gert has become the seventh named storm of the 2017 Atlantic hurricane season and, at category two, it is the strongest one of the year so far.
The warning comes as the tail end of Hurricane Gert spreads across the country.
After the hot spell of scorching weather, parts of England could expected heavy downpours and even "flooding". Rainfall should ease off later in the day, with some sunny spells to break through in the south.
Friday will be mostly cloudy with some heavy blustery showers in the afternoon and evening, as well as fresh gusty west winds.
Monday morning may have opened with grey, damp skies, but a mini heatwave could be winging its way towards the United Kingdom thanks to the remnants of Hurricane Gert.
In the short-term forecast, this Wednesday is expected to see some high temperatures, with London and the South-East experiencing temperatures of up to 24 degrees.
Earlier this week, forecasters said Hurricane Gert would bring risky swells to the east coast of US, before turning into a post-tropical cyclone by Friday.
Temperatures in those regions will likely remain around 18C to 19C on Sunday, while higher ground in parts of western Scotland and north-western England could see up to 25mm of rain - or a third of a month's rainfall - in a few hours.
Skies will cloud over from the west, with outbreaks of rain and drizzle spreading east through the day.
