This GeoColor image animation shows a bomb cyclone bringing an atmospheric river of moisture to the U.S. Pacific Northwest from November 19, 12:00 p.m., EDT [17:00 UTC], to November 19, 7:20 p.m., EDT [November 20, 00:20 UTC]. The imagery was captured by the Advanced Baseline Imager (ABI) instrument aboard the GOES-West (GOES-18) platform. Press the play button in the lower left corner to view the animation.
The bomb cyclone first brought damaging winds on November 19, as one of the northeast Pacific's strongest storms on record, and is bringing extended heavy rain and mountain snow to northern California, Oregon, and Washington through November 22. It is expected that the storm can deliver 12 to 16 inches of rain, increasing chances of flooding, mudslides, and landslides.
