Readiness is All

Readiness is All is the twenty-third episode of the ninth season and the 195rd overall episode of Grey's Anatomy.

Short Summary
The natural disaster will begin in "Readiness Is All" with the storm hitting full force in the May 16 finale, fittingly titled "Perfect Storm." The superstorm will affect the recently renamed hospital and cause its staff to go into crisis mode in an hour that is being described as very intense with a lot of "major" things changing for the characters in the final two episodes of the season.
