Days of sunshine leading up to the warmest days of the year so far are set to be interrupted by more thunderstorms forecast to hit Bucks this week.

A further yellow warning has been issued by the Met Office as cooler weather is expected to come to Bucks and parts of the south east of England from Wednesday.

The weather service is warning of another spell of thundery rain from Friday to Saturday morning, with a small chance of flooding and damage to some buildings from floodwater, lightning strikes, hail or strong winds.

There is also a small chance of fast flowing or deep floodwater causing danger to life, as well as difficult driving conditions caused by spray and sudden flooding.

The Met Office has also said there is a small chance communities could become cut off by flooded roads and a slight chance of power cuts occurring.

It comes after the county has enjoyed several days of uninterrupted sunshine, with temperatures reaching highs of close to 30C on some days.

The weather service first issued a yellow warning of thunderstorms between 6pm on Wednesday to 6pm on Friday.

The further warning is in place from 9am on Friday (June 18) to 9am on Saturday.

The Met Office said: “There is some uncertainty in storm coverage, particularly western extent, but where they do develop torrential rain, intense thunderstorms, hail and frequent lightning are all possible. Rainfall totals of 20-40 mm, perhaps 60mm in a few areas, are possible in 12 hours.

“With the most intense storms, 30-40 mm could fall in an hour or two. The storms should clear into the North Sea during Saturday morning.”
