A series of warm water pulses, known as Kelvin waves, is expected to hit the West Coast this month, potentially raising sea levels by up to a foot. The waves, linked to El Niño, are moving north along the Pacific shoreline, prompting concerns over increased erosion and flooding risks.

The phenomenon, first reported by the Winnipeg Free Press, is part of a larger pattern of oceanic temperature anomalies. These waves, which are not tsunamis but gradual rises in sea level, are causing coastal areas already vulnerable to climate change to face heightened threats. In Washington, local authorities are monitoring the situation closely, while in California, efforts are underway to reinforce coastal defenses with sand barriers.

This event follows a period of increased ocean temperatures, with the Pacific experiencing unusual warmth that has already contributed to beach loss and habitat disruption. Scientists warn that the combination of El Niño and long-term climate trends is accelerating coastal changes. The situation is being closely watched as communities prepare for potential impacts in the coming weeks.
