Land Actions represent the WHOLE time between events. The window is open so long to give people time to enter them without stress, but the actions your characters take start when one event ends and the next begins.
You should treat your action as though it is something that takes you a month to accomplish. The evacuation is only in the few days before the event. You do not need to consider it when doing your action.
