Thunderfest 

A particularly loud, dangerous, or exciting thunderstorm with lots of rain, lightning, and thunder.

I didn't have track today because the rainy conditions of the thunderfest made it too unfit to run outside.

thunderfart 

Expulsion of a large, loud and foul smelling bolus of gas explosively from the anus. Most often, but not always, accompanied by some liquid substance. Has similarities to projectile vomitting in that there is a large volume expelled in a very short time.

The poor child was writhing in agony, and was saved by the inevitable thunderfart.
