Rain?

I am working, as usual, on my balcony. It is a little after 12:30am. It is cool and pleasant.

There is an unusual sound emanating from the south. I am pretty sure that what is happening is that it is raining heavily about a mile south of me. Here, I am on my balcony as usual, and it is dry. But the rain in the south is pounding the aluminum roofs in Nyamirambo, the neighborhood to the south of me.

The result is a remarkable sound. It is both soothing and gentle, and also a little eerie.
