Another major disaster is heading to Seattle in the Grey’s Anatomy season 9 finale. When a freak storm hits the hospital will be affected in a big way.

In Grey’s Anatomy 9×23 “Readiness Is All” a super storm will be heading for Grey + Sloan Memorial hospital according to TV Guide. It will continue into the Grey’s Anatomy season 9 finale episode 9×24 “Perfect Storm” and wreak havoc on the doctors and patients.

The episode is being described as very intense and fans should expect major changes for their beloved characters.

E! Online also revealed that the hospital’s ventilators will stop working. In order to save the patients at risk their loved ones will come in to help keep them breathing.

We’re guessing that the ventilators will stop working due to a power outage. Does this mean that other machines will stop working as well?

Fans will also be wondering about McBaby and whether or not it will be making it’s first appearance in the season 9 finale. Surely having one of the hospital’s board members and valued doctor going into labor in the middle of a freak storm would make a memorable finale.

What do you think will be happening in the ‘Grey’s Anatomy’ season 9 finale? Will Meredith and Derek’s son be delivered in the middle of a storm?
