The Met Office has issued a yellow warning with a risk of potentially severe thunderstorms on Monday night into Tuesday morning.
Between 20 and 60mm of rain has been forecast for regions across the South of England, meaning there is a chance that homes and businesses could experience flooding or damage due to the heavy volume.
Power cuts may also happen, however, the Met Office does not think this is very likely.
In the event of a power cut call 105, you will then be redirected to local people who can help.
It is more likely that this storm will lead to worsened driving conditions, with spray affecting visibility and standing water impacting handling.
The RAC has issued advice on what to do if driving in heavy rain.
Thunderstorms are expected to move north from France on Monday night before clearing into the North Sea by Tuesday morning, Bournemouth and Poole are amongst the local authorities on alert.
Due to how unusual this is for the UK there is a chance of travel disruption on major lines to London; trains and buses may be cancelled.
You can check if your train is running here.
