A yellow weather warning has been issued for Norfolk by the Met Office amid record-breaking September temperatures.

It is in place from 2pm to 9pm on Saturday and the forecaster has said heavy showers and thunderstorms may cause disruption to travel. 

The warning covers much of the west and south of the county.

Flash flooding and sudden showers can lead to difficult driving conditions and some road closures, the Met Office warns. 

Where flooding or lightning strikes occur, there is a chance of delays and some cancellations of train and bus services.

There is also a slight chance that power cuts could occur and properties could be flooded quickly.
