How long do y’all want the flooding to last?

We’re getting to the end of when the arc was scheduled to come to a close, but there’s been little conflict between the clans. What do you think we should be using as a source of tension (sickness, some planned conflicts between leaders and groups, maybe some skirmishes breaking out, etc.) or would you rather leave this arc as one that unifies the clans against, for instance, a drought?
