There are many ways you can approach mindfulness. The whole idea is to get your mind into the present and away from dwelling on things that might happen (which are usually negative things).
You can concentrate on your breathing. Observe the breath going in and out, and if you remember high school biology, imagine how each breath is bringing oxygen to your body and taking away the waste.
You can also try sitting quietly and listening for five different sounds, one at a time. When you hear the sound, think about where it’s coming from, what it means, etc. Don’t use this technique during the storm though, just before the weather picks up.
The technique that’s worked best for me is using an article of clothing or something on your person. Feel it between your fingers, think about what it is or what it does, and think about anything else you can related to the object or piece of clothing.
