It is a storm with both tropical and extra-tropical characteristics (it is currently undergoing the transition), and they're still calling it a hurricane because it's less confusing for the public.
The important note is that, whatever you call it, it is a
powerful and
dangerous storm, and people under manadatory evacuation orders need to heed them. I'm hearing very disturbing figures coming from NJ and NY.

--Oop, I just heard another transformer pop as I write this. I will probably not have power much longer.
edit 2: My barometer just dropped below 29 inches. I have never seen pressure this low.
