Try to recall a time when you wanted to be somewhere, or go somewhere, but a bad storm was coming. You are afraid to leave as you might get caught in it, but you also want to get home as soon as possible. You might pack the car, listen to every weather report, all the while trying to make the right decision.
Do you stay or do you go? What happens either way can make for an interesting story.
Your task is to write a story in which your character is facing bad weather that has the potential to affect travel plans.
Be sure to use lots of dialogue as this is the stuff that can lead to heated arguments. Once the decision is made, bring on the storm and let the emotions play out. Perhaps tornado forces them to hide in the basement, or the snow storm catches them without chains and therefor they slide off the road. Perhaps there are flight delays that strand them at an airport where tempers flare.
All kinds of exciting things can happen.
Have fun with this one.
