When this conversation comes up, first let's define what we need to communicate and with whom?
1. If I communicate with the ham friends I already have skeds with; nothing changes. Turn the radio ON at sked time and start communicating. Of course, if my friends and distant relatives are outside of the impacted area, the radio ops I have skeds with can call my family & friends outside the area, they can relay messages for and from my family. There are times when a 25 word Radiogram is worth it's weight in gold. Morse code works extremely well for my needs.
2. If I want to pass a health and welfare message to friends and family outside of the impacted area (BT&DT) I can use WINLINK. Another gem is The National Traffic System/RRI using nothing more than Morse , paper and pencil with my QRP rig.
3. The first thing I want to know is: 'what is the actual 'impacted area?' Is it my block, my county, my State, half way to Nebraska? That's all information I have generally gleaned from RADIO during past interruptions. Future trends, weather forecasts, storm centers & tracks etc. Plan and act accordingly.
4. I have zero personal need to send a 5 MB PowerPoint presentation to some government entity. YMMV
