COMET_CASE_026: COMET Case Study 026:Pacific Northwest Winter Storm


Case 026 follows an early winter storm moving onshore in thePacific Northwest on November 24, 1999. The storm brought heavy precipitation, while the associated cold front brought strong winds to the coasts of Oregon and Washington. The north Oregon coastline reported high winds November 24, as Conon Beach reported wind of 55-60 knots with gusts to 69 knots, while Arch Cape also reported gusts to 69 knots. The northern Oregon coast reported up to 10 inches of rain, causing flodding and landslides.


The case provides an example of a winter storm in the Pacific Northwest, and allows study of storm/precipitation formation in complex terrain under zonal flow
