Ironically not wind vane is the worst problem. I have seen a Donier shooting down engines directly after vacating rwy. Because engine turbine temperature reached it's limit. Wind is so strong to virtually close the outlets. Even modern aircrafts use plastic or carbon in and around engines what can melt. If need to taxi in high tail wind, some AFMs require minimum N2. That mean constant breaking during that portion.
Wind in storms should not read as 45 knots, gusts 60. It is correctly 60 knots wind but gusts are negative, so in gusts wind is decreased to 45 knots. Strong negative gusts can affect lift because airspeed could be gone. Turbulence near the ground can eat a substantial part of aircraft performance. What is about single engine performance in case you need it.
