San Francisco Mayor Daniel Lurie declared a local emergency on October 23 as the city prepares for a potentially strong El Niño winter that could bring heavy rainfall, powerful winds, elevated tides, and coastal flooding. The declaration allows city departments to expedite purchases of critical supplies, including flood barriers, pumps, and generators, and to coordinate emergency preparations more quickly.

The city is preparing for multiple risks, including flooding from intense rainfall and unusually high coastal water levels. Planned measures include installing temporary flood barriers along vulnerable waterfront areas, clearing storm drains, and preparing infrastructure and emergency response resources. State and local officials across California are also preparing for potential storm-related impacts, although the timing and severity of the coming winter’s weather remain uncertain.

Severe storms, flooding, and coastal inundation can create operational challenges for aquaculture facilities, particularly those located in low-lying or coastal areas. Potential concerns include damage to infrastructure, disruptions to power and water systems, impaired site access, and the need to protect equipment and maintain water quality during extreme weather.
