Currently a problem in the north-east USA, but applicable after every 

People in the south have more experience with hurricanes, and are used to 
this advice.  But apparently, some folks up north aren't in practice.

Never connect an electric generator to home electrical wiring without 
installing a transfer switch to disconnect power from the electric 
grid.  Back feeding electric power into the utility lines is dangerous 
for the repair crews working on utility lines.

Also, never run a generator indoors or in the garage.  Only outdoors 
20-feet away from doors and windows.

FCC has activated DIRS reporting for tropical storm Henri.  So we should 
see some communication system disaster reporting this afternoon.
