Kelvin Wave Threatens Elevated Sea Levels and Coastal Flooding in California
Just the facts
Researchers from NASA's Jet Propulsion Laboratory and the National Oceanic and Atmospheric Administration reported that a massive Kelvin wave is moving across the Pacific Ocean toward North America. The ocean phenomenon is projected to increase sea levels along the California coast by up to 12 inches through the winter season. In anticipation of severe high tides, storm surges, and coastal erosion, California Governor Gavin Newsom declared a state of emergency to deploy state resources and staging equipment. Additionally, the California Coastal Commission urged coastal residents and local authorities to inspect infrastructure and prepare flood defenses ahead of expected seasonal storms.
Why this is news
Scientists and oceanographers warned that a planetary-scale ocean Kelvin wave generated by a strong El Niño is moving toward the California coastline.
