Super El Niño's Kelvin wave could lift California sea levels by up to 30 centimetres

Researchers warn an internal Kelvin wave from this year's super El Niño could lift California sea levels by up to 30 cm once it reaches the coast. The raised water would add to winter storm surges, though the oceanographer quoted expects it to distort tides for weeks.
