NOAA launches first-of-its-kind US rip current forecast model

NOAA has revealed a new national rip current forecast model, aimed at saving lives of beach-goers around the USA. The new model can predict the hourly probability of rip currents along US beaches up to six days ahead.

NOAA’s National Ocean Service and National Weather Service collaboratively developed and implemented the model, which leverages wave and water level information from the recently upgraded National Weather Service’s Nearshore Wave Prediction System.

Similar to predicting weather or precipitation, the model predicts the likelihood of dangerous seaward currents on a sliding scale – from 0 to 100%. The forecast model covers a majority of the US East and Gulf Coast and portions of California, Hawaii, Guam and Puerto Rico. Additional coastline coverage will be expanded in the future.

“Safety for beach-goers and boaters is taking a major leap forward with the launch of this new NOAA model,” said Nicole LeBoeuf, acting director of NOAA’s National Ocean Service. “Extending forecasting capabilities for dangerous rip currents out to six days provides forecasters and local authorities greater time to inform residents about the presence of this deadly beach hazard, thereby saving lives and protecting communities.”

“Improved model resolution will enable forecasters to issue more accurate and detailed rip current forecasts further into the future,” added Allison Allen, chief, Marine, Tropical, and Tsunami Services Branch, NOAA’s National Weather Service. “This information enables public safety personnel to better prepare for hazardous beach conditions and inform the public of potential for danger before they head to the beach.”

“Rip currents account for an estimated 100 deaths in the United States each year,” said Gregory Dusek, NOAA scientist who developed the model. “Before this, forecasters were manually predicting rip currents on a large section of the ocean twice a day and only a day or two into the future. The earlier prediction has potential to substantially increase awareness and reduce drownings.”

Further improvements are on the horizon, according to NOAA, and the application of webcam imagery and AI identification of rip currents is showing promise across the research community. Partners in this work include the Southeast Coastal Ocean Observing Regional Association (SECOORA), the United States Geological Survey (USGS), the United States Lifesaving Association (USLA) and academia.
