This document discusses different types of extreme weather that can cause flash floods, including slow-moving thunderstorms, thunderstorms that repeatedly move over the same area (known as "training"), ice jams that form dams and cause flooding, and torrential rains over a large area. It provides brief explanations of each type of weather event and how it can lead to flash flooding. The document also includes cited image sources and references for additional information.
