A week of thunderstorms across the UK and Ireland delivered heavy rain and lightning, do you know why they are more common as we approach summer?

Before we explore further, we need to understand what causes thunderstorms to begin with. Check out our Weather Explained video below:

As mentioned in our explainer, thunderstorms are more common in summer because the weather helps to fuel their development.

Most important to a thunderstorm are: rising warm air and humidity. Therefore, the more humid the country, the bigger the storms in summer.

A white arrow marks the typhoon’s predicted track towards the north-west, in the direction of Taiwan.
