Yeah absolutely agree, communication blackout probably. Like we are seeing around the world, internet going down for a while, etc.

10 days of no power would be absolutely catastrophic. Power outages are so common that people would wait for it to come back on, running generators. Once those generators ran out of gas, gas stations empty, panic would set in. With stations empty you wouldnt even be able to flee. A lot of people would die.

We just finished an entire week of -30* temps. It would have been a complete disaster.
