In the world of money, the bean counters always say there is a point of 
diminishing returns.

Its impossible to harden a single location against every potential 
disruption. A generator provides some additional resiliancy, but then 
something else would break. Nevertheless, a backup generator still would 
be nice.

The more critical findings concerns WFO Anchorage and WFO Fairbanks 
providing service back up for each other. Any disaster continuity plan 
must prepare for the potential loss of the entire facility, for whatever 
reason.

As the stated in the after action report, the switch over between WFO 
Anchorage and Fairbanks had some hiccups. The assessment in the after 
action report seems fair about the issues. It also recognized the staff 
worked to overcome those deficiencies successfully warning almost all (but 
not everyone) the affected areas.

How many EAS areas have consolidated both LP-1 and LP-2 stations in 
the same building due to mergers and cost savings? I understand that its 
tough enough to find one station to volunteer as a LP, let alone two.

How many EAS areas have an alternete plan if the local WFO facility is 
lost (or the area NWR/SAME transmitters)? I know each WFO is required to 
have a disaster continuity plan.

Stuff always breaks.
