Event narrative (NOAA)
Heavy rain and some snow melt caused flooding that exceeded major severity on the South Fork Nooksack River and mainstem Nooksack River at North Cedarville and Ferndale. There was urban and small stream flooding as well, hitting Bellingham especially hard. The heavy rain also triggered a dozen landslides throughout the area. Significant flooding on the Nooksack River also overflowed at the City of Everson to the degree that flood waters flowed north along an old Nooksack floodway and Johnson Creek where it flooded the cities of Everson and Nooksack, WA, then combined with flooding from the Sumas River and flooded the City of Sumas, WA where over 85% of homes sustained water damage. Damages are reported and estimated; not all damages have been identified. Crop damages are unknown.
