With guaranteed muddy slush and heavy rains. I think Pacific NW eliminated itself from winter Olympics for a long time.
I was there in 2010. No heavy rains at all. It was warmer than usual but there was no rain nor snow. Actually, the lack of precipitations was a bit of an issue which was solved by shipping snow from some mountains to the competition sites. For spectators, it was a two weeks of bliss because it was so sunny and nice that we could walk downtown without umbrellas or heavy clothing and enjoy all the activities. Not sure what you mean by heavy rains. It was not perfect weather but it was great games
