1/4/2017 11:00 AM 0.56 5.9 M 26.0 M The snow level in the water measuring gauge was 11.0 inches. The 5.9 inches was on the snow measuring table. The wind blows the snow so much that it is difficult to know the level of the snow.
1/5/2017 8:00 AM 0.76 8.0 M 34.0 M Because of wind,snow level on measuring table was 8.0 inches while the snow in the water gauge was 12 inches.
