The morning was chilly but with almost no wind. Wind speed in the afternoon was wildly inconstant, with some gusts over 60 km/h but there were also calm periods. Judging by the snow coming off the mountains, wind at ridge level was often very strong but also inconsistent. Cloud cover increased from 10% at the start to 100% as a sheet of altostratus passed over around noon, then varied from 60% to 80% for the rest of the day.

It was fairly slow with 13 eagles passing by between 12:17 pm and 5:20 pm. 9 Golden Eagles used the eastern ridges and were detected near Mount Lorette or high over Patrick, 3 Bald Eagles moved north along the river valley and 1 unidentified eagle was briefly seen before it disappeared behind Hummingbird Plume Hill.
