The Met Office has issued a yellow weather warning for rain this weekend in London.
The warning has been put in place from midnight on Sunday to 3pm on Sunday afternoon.
There is currently eight hours of rain forecast throughout the span of the warning - starting at 6am and ending at around 2pm.
The forecaster warned that a short period of heavy rainfall may bring "some localised flooding and transport disruption".
This means bus and train services will probably be affected and flooding will impact homes, businesses and journey times.
Other parts of the UK have a weather warning in place on Friday and Saturday - but the battering conditions are only due to hit London towards the end of the weekend.
Here's what the Met Office said to expect:
- Flooding of a few homes and businesses is likely
- Bus and train services probably affected with journey times taking longer
- Spray and flooding on roads probably making journey times longer
