Given:

The weather department has predicted that a thunderstorm is likely to occur on a certain day.

To do:

We have to decide whether we should take an umbrella with us if we have to go out on a thunderstorm day.

Solution:

If there is a prediction from the weather department that a thunderstorm is likely to occur, we should not carry an umbrella to avoid an electric shock. Let us know why we should not carry an umbrella with us on a thunderstorms day:

Thunderstorms are accompanied by lightning:

It is a known fact that thunderstorm is a storm that is accompanied by thunder and lightning generally. Lightning is an electric discharge that occurs due to opposite charges in the cloud that causes a loud sound which is called thunder.

Holding an umbrella may give an electric shock:

Based on the above discussion we can conclude that electrical discharges can travel from clouds to metal umbrella rods as metals are good conductors of electricity. The electric discharge from the clouds can cause an electric shock if we are holding an umbrella.

Therefore, we should avoid carrying an umbrella with us on a thunderstorm day to avoid electric shock.
