NOAA’s GOES West satellite has recently highlighted the severe weather phenomenon affecting northern California, the Pacific Northwest, and British Columbia from November 19 to 20, 2024. The event features a formidable mid-latitude cyclone combined with an atmospheric river, prompting significant rainfall, powerful winds, and substantial mountain snow across the region.
The enhanced color imagery captured by the Advanced Baseline Imager illustrates a powerful low-pressure system positioned roughly 300 miles off the Washington coast, harnessing moisture from the Pacific. This combination of factors has led to hurricane-force winds, resulting in tragic fatalities and leaving hundreds of thousands without electricity. Damage to trees and infrastructure has been extensive, and blizzard conditions have been reported in the Cascade Mountain range.
This weather system, referred to as a “bomb cyclone,” demonstrates a rapid drop in central pressure, signifying the storm’s intensity. Such events carry an increased risk of flash floods, rock slides, and debris flows, challenging the safety and resilience of local communities.
The GOES-18 satellite, operational since February 2019, continues to provide critical geostationary satellite coverage across the Western Hemisphere, aiding in monitoring and responding to severe weather systems.
Despite the challenges posed by such intense weather events, the extensive monitoring capabilities of satellites like GOES-18 are pivotal in preparing and responding to natural disasters, enhancing the ability to mitigate risks and protect lives.
In summary, while the storm has resulted in significant challenges and risks, the technology and data from NOAA’s satellites are invaluable in understanding and navigating these severe weather occurrences, hopeful for better preparedness and resilience in the future.
