The Met Office said thunderstorms were expected to move north-westwards across some parts of the region bringing spells of heavy rain and frequent lightning with potential for 15 to 25 mm of rainfall in one or two hours. 

Hail and gusty winds may also affect certain locations. 

Drivers should be aware that spray and sudden flooding could lead to difficult driving conditions and some road closures. 

There is also a chance some train and bus services may be cancelled or delayed where flooding or lightning occurs. 

Authorities said there was a slight chance that power cuts could occur and other services to some homes and businesses could be lost. 

There is also a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds. 

The warning map notes the rainfall and storms may affect areas north of the county such as Charlbury and Bicester as well as everywhere in Oxfordshire south of those locations.
