Since ive been in Hatteras I have heard about the infamous switch of wind from SW to NW in the matter of minutes. Yesterday we saw it in action. It was around 11:00 and ryan when to go grab his board from out side when he looked up and saw a wall of rolling clouds barreling towards the house on a perfectly clear night. He yelled at us to come check it out. Sure enough the wall of clouds (it looked like the mothership from Independence Day) was the NE front moving in quick. It went from SW@15 to NW@30+ . It was crazy to say the least. We stood on the front porch watching the front roll in. As it passed over our heads the 30+ winds hit like a truck. It was quite an experience. I was glad we were not out kiting at the time.
