I guess a experienced climber was blown off the keyhole last week, he was climbing by himself, and the route was paved in verglass. He's ok, just sustained minor injuries. Let this be a reminder to bail, when the weather is shit.
Interesting ... that route can be very windy. It was only a little windy when I climbed it in September but probably gusting over 40mph, so we tried to stay on the E side.
Don't forget also to hike with a string trailing you, just in case someone needs to fly a kite, perfect opportunity. You could even step it up and tie a key into the string for the electrical effect during a storm.
The highest wind gust recorded on Longs was Winter 1981 at 201mph before the wind gauge broke. Since there is no continuous monitoring (as on Mt Washington), there is a good probability that faster winds have occurred.
Anyone that has been on Longs during a typical wind storm experiences: the vacuum that sucks your breath away as you face downwind; hearing the ominous roar of an approaching wind gust; hugging the ground waiting for a lull to move forward; and of course there is no such thing as peeing down wind in such hurricane force winds.
