Monterey Bay temperatures reached a record 18.18°C on Oct. 26, and researchers say El Niño-associated warm water is arriving via Kelvin waves. Scientists expect continued warming could disrupt food supplies and marine ecosystems; unusual warm-water species have already been observed in the bay.
Biologists are preparing for the possible hatching of 204 olive ridley eggs relocated to the Aquarium of the Pacific after high tides threatened their Orange County nests. Hatching is uncertain, but if it occurs, it would be the first known sea turtle hatch on the U.S. West Coast; the article says an extreme marine heat wave and strong El Niño warmed Southern California waters and helped make nesting there possible.
Humboldt County supervisors abandoned a $3.8-million plan to elevate and armor Centerville Road, citing rapid bluff erosion and the risk that nearby sections could collapse. They directed staff to plan a route farther inland; the article notes a “super” El Niño is on the horizon but does not explicitly attribute the erosion or decision to it.
Forecasters expect a warmer-than-average U.S. winter, with above-average precipitation in several regions, though conditions remain uncertain. The article links El Niño to shifting regional risks, including coastal flooding and drought-relieving rain, and says it may have contributed to recent Southwest floods alongside a marine heat wave.
Las mareas excepcionalmente altas inundaron zonas bajas de San Diego, dañaron una barrera de arena en Mission Bay y dejaron un automóvil inutilizado; un registro de NOAA superó en más de un pie el nivel previsto. Expertos advierten que mareas rey y posibles lluvias podrían agravar las inundaciones en los próximos meses, y el artículo vincula explícitamente los altos niveles del mar con El Niño.
San Diego officials warned of intermittent coastal and street flooding this week from elevated tides, Kelvin waves, seasonal high tides and forecast rain. Flooding already briefly closed part of West Harbor Drive, and a coastal flood warning was in effect through Thursday afternoon, with unusually high tides forecast to inundate low-lying areas.
Record-high tides flooded parts of Mission Bay and other low-lying San Diego areas, damaging property and stranding a car. Officials and residents warn that high tides, possible winter storms, and forecast rain could bring further flooding; a Scripps oceanographer said El Niño is contributing to elevated sea levels that may combine with unusually strong Christmas king tides.
El Servicio Meteorológico Nacional emitió una alerta por inundaciones costeras para los condados de San Diego y Orange hasta el jueves por la tarde, ante la previsión de mareas inusualmente altas que podrían causar inundaciones y cierres de carreteras. Hasta el domingo no se habían reportado daños en San Diego; también se prevén temperaturas más cálidas al comienzo de la semana y lluvias posibles desde el viernes, aunque su momento y cantidad son inciertos.
Metrolink plans to suspend Orange County Line service between Oceanside and Laguna Niguel/Mission Viejo Monday through Friday because of anticipated high tides near San Clemente; no replacement buses will be provided. Amtrak trains are expected to continue operating if conditions remain safe, while crews monitor the coastal tracks.
The NWS issued a coastal flood warning for San Diego and Orange counties through Thursday afternoon, forecasting significant flooding from unusually high morning tides, possible road closures, inundation and shoreline erosion. No damage had been reported in San Diego County as of Sunday morning; rain later in the week remains possible but uncertain.
