California – Atmospheric River‑Related Flooding
Situation
Over the last five years, unprecedented wildfires scarred thousands of square miles of California forest and rural lands.
Combined with atmospheric river weather conditions, California finds itself particularly susceptible to severe flood and mud slide catastrophes.
In these emergency situations, California’s public safety professionals need a seamless emergency communications system that is two‑fold:
- To provide critical interdepartmental collaboration tools that allow responders to operate safely during and after the event.
- To notify the public of safety and evacuation information.
Problem
During December 2022 and January 2023, counties across California experienced multiple flooding, mud slide, and storm‑surge events related to atmospheric river conditions.
While these moisture plumes or vapor surges are crucial to the water catchment areas along the West Coast in the United States, they also have the potential to create significant and dangerous flooding conditions requiring swift responses from emergency management personnel.
Solution
More than ten of these counties, including Los Angeles, Humboldt, and Santa Cruz, used the Genasys Protect solution to coordinate their responses and communicate critical information to the public.
Through a single dashboard, county responders were able to communicate and plan, while staying advised of situations, routing first responders, and notifying their citizens of evacuation information that aided in lifesaving efforts to keep the community safe.
During the unprecedented series of atmospheric river flooding events during the winter of 2022‑2023, agency officials in more than ten California counties managed flood advisories, road closures, and shelter operations to safely direct citizens and emergency personnel.
These efforts along with the right tools minimized loss of life during a series of catastrophic weather events that will only become more common as global temperatures continue to rise.
