加利福尼亚州已正式宣布进入紧急状态，以因应太平洋上持续增强的圣婴现象所可能引发的严重风暴、大规模洪水以及土石流威胁。州长加文·纽森于周一发布了这项紧急声明，要求相关政府部门提前做好防灾准备。

为降低即将到来的灾害风险，州长指示各州立机构评估排水系统等重要基础设施，并加速推进保护公路与桥梁免受洪水及海岸侵蚀的工程。圣婴现象源于赤道太平洋海水异常变暖，历史上曾多次为加州带来伴随强降雨与厚重积雪的极端潮湿冬季。

尽管最剧烈的降雨可能还需要数周才会抵达，加州各地官员与居民已全面展开防汛作业，包括建造防洪海岸护堤以及向公众发放沙袋，以全力保护居民住宅与商业设施免受水灾损害。

California has declared a state of emergency as a strengthening El Niño in the Pacific Ocean increases the threat of destructive storms, widespread flooding, and mudslides throughout the upcoming fall and winter. Governor Gavin Newsom announced the proclamation on Monday to mobilize state resources early.

In preparation for the impending weather risks, the governor directed state agencies to inspect critical infrastructure such as drainage systems and accelerate flood-mitigation projects designed to protect highways and bridges from coastal erosion. El Niño, driven by equatorial Pacific warming, has historically brought exceptionally wet winters with heavy rainfall and mountain snow to California.

Although the most severe storms are expected weeks away, officials across California have already initiated flood-defense measures, including constructing coastal barriers and distributing sandbags to the public to safeguard homes and commercial businesses.
