T'was the Night Before Christmas...and I was testing Hurricane

When I got my new staff from heroic Grim Batol today, I decided I finally had a weapon worth enchanting with the new Hurricane enchant. 

The following test is inconclusive due to the nature of what causes the Hurricane buff to exist.  

I tested it as fire without buffs of any kind and did 250 Scorch casts that procced 107 ignite DoTs.  Scorch has a cast time of 1.39 seconds on my Mage.  Hurricane procced 9 times.  I cannot assume that it only procced off of the Scorch Casts, as people have noted Hurricane proccing on any number of things (See the comments in the posted link).

If we total in ignite DoTs as a potential cause of the Hurricane procs, that would suggest that Hurricane procs roughly every 40 casts, or about once per minute.
