What is a rip current? - NOAA's National Ocean Service
Rip currents are powerful, narrow channels of fast-moving water that are prevalent along the East, Gulf, and West coasts of the U.S., as well as along the shores of the Great Lakes. Moving at speeds of up to eight feet per second, rip currents can move faster than an Olympic swimmer.
Rip Currents - NOAA's National Ocean Service
A rip current, sometimes incorrectly called a rip tide, is a localized current that flows away from the shoreline toward the ocean, perpendicular or at an acute angle to the shoreline. It usually breaks up not far from shore and is generally not more than 25 meters (80 feet) wide.
NOAA Launches First National Rip Current Forecast Model
For the first time, NOAA is launching a national rip current forecast model, aimed at saving lives of beach-goers around the country. This new model can predict the hourly probability of rip currents along U.S. beaches up to six days out.
Rip Currents: Preparedness and Prevention - Podcast: Episode 66
Rip currents are powerful, channeled currents of water that can move at speeds of up to eight feet per second, and can occur at any beach with breaking waves. This image shows a rip current using a harmless green dye.
Rip Currents - Discover Your World - NOAA's National Ocean Service
Rip currents are powerful, channeled currents of water flowing away from shore. They can occur at any beach with breaking waves, including many Great Lakes. These currents are killers.
Currents: NOAA's National Ocean Service Education
Rip currents are powerful, channeled currents that flow away from shore and can occur at any beach with breaking waves. Rip currents can be killers and account for over 80% of rescues performed by surf beach lifeguards.
Ten Dangers at the Beach - NOAA's National Ocean Service
Rip Currents Rip currents account for more than 80 percent of rescues performed by surf beach lifeguards. They are powerful, channeled currents of water flowing away from shore that quickly pull swimmers out to sea.
Thermohaline Circulation - NOAA's National Ocean Service
These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.
Currents - NOAA's National Ocean Service
Currents driven by thermohaline circulation occur at both deep and shallow ocean levels and move much slower than tidal or surface currents. The Currents Tutorial is an overview of the types of currents, what causes them, how they are measured, and how they affect people's lives.
