You could monitor the level of the fluid in the PAS reservoir. Or wait until it starts making groaning sounds on full lock!
Mine seemed to go very suddenly. I don't recall the PAS groaning on full lock before arriving home and then reversing onto the drive to find the steering incredibly heavy.
If is is that, the good news is that it's relatively cheap to repair. A suitable length of hydraulic hose and some fluid.
