no dont jump straight into the hurricane. make sure you get slightly into boardslide first and then slide into a hurricane, otherwise you might go over the rail and ive never seen someone fall and still be able to ride after doing one of those. it hurts really bad and its super dangerous to jump right into the hurricane, it happened to me and i have a serious mental block from doing them now.
just practice pushing your back foot into the rail and pulling your front foot in the opposite direction right when you get onto it, and try and make it so you are on top of the rail as possible, dont lean off to the side you jumped on to it from, otherwise you won't be able to lock in. its all about the push and pull of your feet/lower body, dont spin on to it or basically, dont go fakie on to it. you should still be able to see in front of you/be faced the same way you started
