On November 19 and 20, 2024, NOAA’s GOES West satellite captured striking imagery of a powerful mid-latitude cyclone alongside an atmospheric river affecting regions in northern California, the Pacific Northwest, and British Columbia. This weather event has been characterized by strong winds, torrential rain, and significant snowfall in mountainous areas, raising concerns over flash floods, rock slides, and debris flows.
The satellite imagery displayed the low-pressure system rotating approximately 300 miles off Washington’s coast, actively pulling in moisture-rich air from the Pacific Ocean. This potent combination has resulted in dangerous winds resembling hurricane strength, leading to at least two fatalities and leaving hundreds of thousands without electricity. Extensive damage to trees has been reported, coupled with blizzard conditions in the Cascade mountains. The storm has been classified as a “bomb cyclone,” marked by a rapid drop in central pressure, indicating a swift intensification of the storm.
GOES West, also referred to as GOES-18, has been instrumental in monitoring weather patterns throughout the Western Hemisphere since its launch in March 2018 and its full operational status in February 2019.
This event highlights the increasing frequency and intensity of extreme weather phenomena, underscoring the need for preparedness and resilience in the face of such natural hazards. Communities in the affected areas are being encouraged to remain vigilant and follow safety guidelines during this tumultuous weather shift.
In light of these challenges, it is crucial to focus on rebuilding efforts and enhancing infrastructure to better withstand future storms. Additionally, this serves as a reminder of the importance of ongoing climate research to understand and mitigate the impacts of such drastic weather changes.
