I was watching the rudder at the moment of the low level right bank. It did not seem to have been 'stood on' - left - to the reduce the drift and then right aileron (perhaps too much) to keep wings level. Mother nature biting you with no warning. Like all ladies she needs gentle but firm handling. No back-chat.
It is surprising to see AMS (6 rwys) reduced to single operation by NW storms. It is more common than you might think and there are very few alternates in the region. EDDK Cologne is the only NW rwy. Most other rwys are more SW'ly and thus worse X-winds. Fuel in the tanks and a solid plan are essential on such days.
