I backpacked in the Caribou-Speckled Wilderness SAT/SUN and the forecast I looked at is definitely not what I got, particularly the wind. We camped out on the open ledges down on Cold Brook Trail and went to bed around 10PM to calm winds (Forecast I had last looked at I believe called for like 6-8 mph winds). At about 12:00am I was in an upside down tent in a small puddle trying to find the zippers for my door to flatten out the tent and get it out of the wind and find all the my gear. Got hit with a huge gust that was hard enough to blow my 225 lb body, my gear, a 6-8 lb rock I was using in one corner of the tent as an anchor and my other stuff up and over. To be fair, I wasn't staked in or tied down because it was supposed to be calm and I was on solid ledge and my tent orientation was perpendicular to the eventual wind because that is how the ledge was oriented. Was pretty cool experience actually (although it probably would have been different if it had rained - we didn't see any after about 5PM but you could see the random showers scattered all over the area). I was with a first time backpacker and her EMS tent was flailing around like a shopping bag hooked on the bumper of a car driving down the highway. She took it like a pro though. We had a good time. I can only imagine what was going on up on the higher peaks. We were only at about 2400' or so and somewhat shielded by Speckled Mountain's South shoulder and we were seeing wind gusts of probably 30-40mph.
