If possible, sleep in a car/camper. We slept in a tent and kept our cooler and bags in it so the tent was fine but the wind was super loud. In my experience, it wasn’t constant wind but it came in random gusts. Sand bags are the best for holding things down! Bring a hoodie and a beanie

Whatever you think is staked down enough, double it. And take canopies down if you’re not using them. My last time at gorge was a couple years ago but I had JUST gotten a new car the day before and drove it to the gorge. A wind gust came out of nowhere and picked up our canopy (that was staked down) and smashed it against the windshield of my car, shattering it.
