California Coast Faces Rising Sea Levels Due to Unusual Wave
WHO:
Phys.org - California residents and officials are involved in addressing the rising sea levels.
WHAT:
ABC News - Sea levels along the West Coast will begin to rise by up to a foot this month due to a series of pulses of warm water called Kelvin waves.
ABC News - The surge will move north along the California coast at about 6 miles per hour (9.6 kilometers per hour), or 150 miles per day (241 kilometers per day).
ABC News - Experts predict the waves will continue to pass through from October until February.
ABC News - The Kelvin waves are expected to raise sea levels between six to 12 inches higher.
Phys.org - Sea levels in California are set to rise by as much as a foot (30 centimeters).
NY Post - California could soon see its highest sea levels ever recorded.
WHERE:
Phys.org - The event is occurring along the California coast, specifically affecting the U.S. West Coast.
WHEN:
Phys.org - The rise in sea levels is expected to occur in the coming days.
WHY:
ABC News - The Kelvin waves are common during El Niño events, and this year’s super El Niño could intensify the impacts.
Drudge Report - An unusual wave phenomenon is causing the sea levels to rise.
HOW:
ABC News - Kelvin waves are described as bulges of water that lift the sea level as they move along the coast, similar to water sloshing in a bathtub during an earthquake.
Drudge Report - The phenomenon involves an enormous wave washing up the U.S. West Coast.

Sea levels along the West Coast are set to rise by up to a foot this month due to a series of warm water pulses known as Kelvin waves, which are expected to continue from October until February. These waves will travel north along the California coast at about six miles per hour, raising sea levels between six to twelve inches higher as they move. Experts note that these Kelvin waves are common during El Niño events, and this year's super El Niño could further intensify their impacts.

California residents and officials are actively addressing a significant environmental challenge as sea levels along the coast are projected to rise by as much as a foot, or 30 centimeters, in the coming days. This rise is expected to result in the highest sea levels ever recorded for the state, driven by an unusual wave phenomenon that is washing up the U.S. West Coast. As the situation develops, communities are bracing for the impact of these rising waters.
