Heavy rain has been forecast beginning at midnight and lasting most of the day on Friday, and between midnight and 11pm on Saturday.
London is set to see persistent downpours from the early hours of Friday, with heavy rain continuing until midday before easing to lighter showers through the afternoon.
Conditions are expected to worsen again from around 7pm, with another spell of heavy rain lasting into the night.
Saturday will bring a much drier but overcast day, with cloud cover dominating from the early hours through to late evening.
Temperatures are set to remain cool, with highs of 14°C and lows of 10°C on Friday, dropping slightly to a maximum of 12°C and a minimum of 8°C on Saturday.
