- Rip currents are strong, narrow channels of water that flow out, away from shore. They tend to occur near sandy beaches, where trenches and breaks in the sandbar form off the shoreline on the lake bottom. These powerful, channeled currents often develop because of high wind, waves, shoreline structures (such as piers), and weather phenomena. Rip currents can pull even the strongest swimmers far from the shore, at an average speed of approximately 2 feet per second.

- Inundation can arrive in different ways. In the classic scenario, it arrives as a series of waves, with the first wave with slight inundation followed by a withdrawn sea (extended dry shore) by a series of large waves. In other scenarios, this is more muted with a slight withdrawal then the sea coming in as an extended, prolonged flood such as the 2004 Indian ocean tsunami shown here. Occasionally, it can be lead by a massive shoaling wave, but this is less common.
