Word Vomit

Try capturing strong emotions, in general terms, use a free write. Some writers call this "Word Vomit" where you just pour out the words on paper. Try to avoid dropping names. Make it purely a descriptive.

Save these outbursts. Remember that artists thrive on emotion, and art in anything that evokes an emotion, no matter what that emotion is. If you have these scraps saved then you can come back to them for your writing even a year from now.

Its great for when random settings present themselves to you. When I drove from PA to Utah I saw foggy mountain passes, oppressive storms and drove through a spaghetti bowl of interstate bypasses in Wisconsin. If you can take a break, stop for gas and write everything down. You can use it later.

I make a practice of sending my self text messages or accessing One Note on my phone.

This makes things easier for me because I'm not a very emotional person. I have a tendency to be coldly analytical, I detach, and my honest puts people on edge. Lying people are comfortable with, they don't trust honest. So I am training myself to a path of "better left unsaid" and trying to save things like descriptive actions for my writing.
