An alternative that the new team might consider using (in this very outlier circumstance) is remaking the primary raffle threads and pinging everyone over to the new one to do some prize drawing, with the understanding that prize distribution will be delayed due to the emergency. Collect receipts and document the final drawing outcomes, and then (once the 'out in an emergency' organizer is availabe) do the actual prize distribution.

This has the benefit of communicating the situation to everyone impacted by the outage.
