The May rain has started to fall.

Acid rain destroys forests and has a serious impact on ecosystems.

I encountered a tree rain in the park.

Surprised by the sudden heavy rain, I forgot my umbrella.

Outside the window, a small amount of rain is falling.

When I looked out the window, it was drizzling.

Suddenly, a rainfall that starts and stops abruptly began and then stopped immediately.

The sound of the night rain hits the window glass.

The sound of the night rain is hitting the window glass.

The rainfall that suddenly started and stopped made me realize that I didn't have an umbrella.
