It was bad...If only LIPA our electric supplier would bury the power lines
then there would be little chance of the same electric problems happening again. They supply electricity to nearly all of Long Island, NY and are a monopoly here.
After all, we're in the path of virtually all the hurricanes that travel up the east coast.

Flooding--well, there isn't anything anyone can do about that.
My primary concern is that the chams will get too cold.
A few days without lights would probably not be so bad but no heat can be a much bigger problem IMHO.
Without a generator, Randi's suggestions are all good ideas for hours but not days. Even a battery backup will only power an incandescent bulb for a few hours at best.
If you have a fireplace or wood stove for heat, then at least they won't be in danger from getting too cold but you'll have to do things to keep the humidity up.
If you're able to boil water, then you can put large pots of boiled water in your cham's room.
Unless you are in a rural enough area, your neighbors won't like the noisy generator running at night.
Bottom line; get a generator and stock up on extra gasoline when a severe storm threatens.
