With it being autumn, there's plenty of the wet stuff about in many parts of the world - including in the Netherlands, where I currently live. Whether it's the whisper of a light drizzle or rain that feels like it's both horizontal and made of bullets, you can be sure to find some here.
Whether you want to write about tropical rain (I seem to recall the rain in Florida practically being warm enough to bathe in) or autumn rain, create a shape poem in the form of rain, or just play with the homophones of rain, reign and rein, all options are open here today.
Remember, our prompts are only suggestions; you can find your inspiration wherever your muse leads you. Please visit the other participants' work, share the hashtag #OctPoWriMo on social media, and share your link in the comments below. Let us know how this journey into poetry is going for you.
