The Met Office has warned Londoners to take care as the capital faces heavy rain and strong winds.
The authority issued a yellow warning for London and the South East, as areas of rain and heavy winds are expected across much of southern England on the evening of Friday, July 24.
This was an update on a warning made the previous day, as the authority said there was now an increased likelihood of localised flooding, especially across the South East.
These areas are also most likely to be affected by northerly gales, with winds gusting to 45mph in land and around 55mph in coastal areas.
The forecasters said the public should be aware of the potential for disruption, particularly affecting those travelling or engaged in outdoor holiday activities.
Rain is expected in the capital for a number of days with some sunshine breaking through on Thursday, July 30.
