We can get plenty of rain that time of year, so you'll probably want a tent you can put your gear in, while you're inside. Which means a two-man for one person IMO.
With a good-sized vestibule you can use to stash wet boots and rain gear, and run your stove in if needed.
I've been thinking about getting one of those so I'll be following this thread. A decent-sized vestibule is a must for me anyway.
