The Met Office has issued two yellow weather warnings for thunderstorms in Oxfordshire.
The first warning is in place later today from 12 noon until 8pm (September 20) and the second is in place from 1am until midnight on Saturday (September 21).
The forecaster said while many places will remain dry, thunderstorms and heavy showers could cause some disruption on both days in a few places.
It means spray and sudden flooding could lead to difficult driving conditions and some road closures and there is a small chance that some communities become cut off by flooded roads.
There is also a chance of delays and cancellations on public transport and a slight chance of power outages.
Oxfordshire County Council is warning drivers to take extra care.
