I'm not sure if the headwind was 25 mph or 35 mph, but it was quite strong. Our 2012 Jeep Wrangler's hood didn't like it much, though. I was going 70 mph, but from the hood's point of view the wind was striking it at 100 mph.

The middle of the hood is doing a fair bit of oil-canning, and the legacy over-center hood latches, which are made of a rubbery material, are stretching and letting the hood move around. It's not going to fly up because of the positive metal safety catch in the middle, but it is annoying.
