Would a windshear alert be generated at 2000'? Normally 1500' is the cutoff... but I don't have any A320 manuals to hand in order to verify that statement.
As to the rest, winds can do that, A/floor is a possible consequence but until any of us see the data or the report absolutely none of us can comment...
ps. F+1F isn't an A320 conf setting I've heard of [pedantic mode;-)]
