A rip current (or just rip) is a specific type of water current that can occur near beaches where waves break. A rip is a strong, localized, and narrow current of water that moves directly away from the shore by cutting through the lines of breaking waves, like a river flowing out to sea.
A rip current statement is a warning statement issued by the National Weather Service of the United States when there is a high threat of rip currents due to weather and ocean conditions. [1] The statement usually contains some detail about when and roughly where the rip currents are most likely to be forming.
Rip currents can flow quickly, are unpredictable, and come about from what happens to waves as they interact with the shape of the sea bed. In contrast, a rip tide is caused by tidal movements, as opposed to wave action, and is a predictable rise and fall of the water level.

A rip current is a horizontal current. Rip currents do not pull people under the water—they pull people away from shore. Drowning deaths occur when people pulled offshore are unable to keep themselves afloat and swim to shore. This may be due to any combination of fear, panic, exhaustion, or lack of swimming skills.
Rip currents have been measured at speeds of more than 5 miles per hour, which is faster than an Olympic swimmer. They can quickly sweep away even the strongest of swimmers.
In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry. In tidal zones, the current and streams may reverse on the flood tide before resuming on the ebb tide.
A current in a fluid is the magnitude and direction of flow within each portion of that fluid, such as a liquid or dynamic Types of fluid currents include: H2/<e=mc2/+1; Current (hydrology), a current in a river or stream; Ocean current. Longshore current; Boundary current; Rip current; Rip tide; Subsurface currents. Turbidity current; Tidal ...
