ARkStorm

An arkstorm is an extreme weather event that brings an excessive amount of rain and snow over a large area. It usually happens in the western part of the United States, but can happen anywhere. During an arkstorm it can rain and snow very hard for days, flooding cities and causing lots of damage. It can also cause mudslides and rock slides, which can put people in danger.
