Compressor Stall
In my my time belting around the NT and Arnhem Land in a 210, I usually stayed low late in the day in the buildup. Except for the escarpment there's not much to hit and except in really monsoonal trough times, the clouds are not normally on the ground. If they are, then you don't want to be anywhere near it anyway down low or up high.
Was it you that stole my Northern Territory SOP manual?
