The NOAA’s GOES West satellite, also referred to as GOES-18, has recently provided striking imagery of a formidable mid-latitude cyclone and an associated atmospheric river that influenced northern California, the Pacific Northwest, and British Columbia on November 19-20, 2024. This significant weather event has brought about damaging winds, heavy rainfall, and substantial snowfall in the mountains, leading to heightened risks of flash floods, rockslides, and debris flows in the affected areas.
The satellite imagery captures the intense low-pressure system, positioned approximately 300 miles off the coast of Washington, which has been pulling in a robust atmospheric river from the Pacific Ocean. This powerful combination resulted in hurricane-force winds that have tragically led to at least two fatalities, left hundreds of thousands without electricity, and caused considerable tree damage. Furthermore, blizzard conditions were reported in the Cascade mountains. This storm is notably intense, classified as a “bomb cyclone” due to its rapid drop in central pressure, signifying a swift intensification.
GOES-18 provides critical geostationary satellite coverage over the Western Hemisphere, including key areas such as the United States and parts of the Pacific. Since becoming fully operational in February 2019 after its launch in March 2018, the satellite has been an essential tool in monitoring severe weather patterns, helping to enhance our understanding of such phenomena.
While the effects of this storm have been devastating, it serves as a reminder of the power of nature and the importance of weather monitoring. Strides in technology, such as those exemplified by the GOES-18 satellite, empower communities to prepare for and respond to such events more efficiently. The ongoing advancements in meteorological science ultimately contribute to improved safety measures and climate resilience.
Overall, even in the face of significant challenges posed by these weather systems, there is hope that enhanced monitoring and emergency preparedness can mitigate impacts and support recovery efforts.
