Kelvin Waves, Explained

10/11/2026

By fisheries.noaa.gov, fisheries.noaa.gov. You may be hearing a lot about Kelvin waves in the news. What are Kelvin waves, and how are they related to El Niño? We asked oceanographer Michael Jacox, from the Southwest Fisheries Science Center and NOAA Physical Sciences Laboratory, to explain the phenomenon. What is a Kelvin wave and… SEE MORE

How Will El Niño Affect Your Local Fisheries?

10/10/2026

By fisheries.noaa.gov, fisheries.noaa.gov. What does El Niño mean for U.S. fisheries and marine life? What can fishermen and coastal communities expect to observe and experience as this event continues and potentially intensifies? And what are scientists at NOAA Fisheries doing to track this natural phenomenon? The El Niño-Southern Oscillation is a powerful… SEE MORE

NOAA’s flood mapping tool now covers nearly 100% of U.S.

10/7/2026

By fisheries.noaa.gov, fisheries.noaa.gov. NOAA’s National Weather Service announced today that Flood Inundation Mapping (FIM), a revolutionary tool for predicting river flooding, is now available on an experimental basis to nearly 100% of the U.S. population. This is a massive expansion from FIM’s prior coverage of 60% of the country. FIM… SEE MORE

Coastally-trapped Kelvin waves, a signature of El Niño, traveled north along the West Coast during the 1997/1998 El Niño, as shown in a map of sea surface height anomalies. Darker reds show sea levels higher than normal, while darker blues show heights below normal. Scientists are now watching for similar waves to move up the West Coast this fall.

Ocean Indicators Help Track El Niño’s Arrival on the West Coast

9/5/2026

By fisheries.noaa.gov, fisheries.noaa.gov. Has El Niño reached the West Coast? You might think it has. After all, the ocean off Southern and Central California is unusually warm. But that is from a recent marine heatwave predates the current El Niño. Much of the Pacific Coast is experiencing relatively normal conditions while still… SEE MORE
