Story Concept Brainstorming - Help Develop my next writing Project

Almost a year ago, I wrote about the concept of a story. In simple terms, a story can start as a concept, framed in the form of a what if question. The answer to the question, to your concept, becomes the story. The concept is the platform from which the story can enfold. Let me give an example of a story concept. What if a boy didn’t know he was a wizard?

The what if question above is the concept for the Harry Potter series. I use the what if questions to help me map out story ideas and outlines. And right now, I'm in the midst of figuring out what my next writing project will be and would love your feedback as I flesh them out.

Below I have a few story concepts (what if questions). Your task is to give a possible answer to the what if question - to tell me how the story will enfold from the concept. Or you can ask a follow up question or give me a completely new story idea. There are no wrong answers, so have fun with it! Just leave your feedback in the comments. Here you go.

What if it didn't stop raining for 40 days?

What if a teenage boy's mother passed away during his senior year of high school?

What if every part of the world below 1,000 feet above sea level was underwater?

What if a teenage girl learned her father was cheating on her mother?

What if a 4 year old Boston Terrier named Daisy moved in with Zelda the Pug (Of the Adventures of Zelda series)?
