If you need to monitor processes in realtime, use iotop instead.
top can show total amount of iowait of all processes in wa parameter:
wa, IO-wait : time waiting for I/O completion
In addition with top you can see load average that show average number of running + waiting threads. This metric can indirectly indicate disk problems

Is the WA measured in percentages and updated in real time?

@fsefs, yes it is. From man pages:As a default, percentages for these individual categories are displayed.
