Connecticut Light and Power offers the following tips: Check medications that need refrigeration. You may want to keep a small cooler handy for that purpose. Have a supply of canned, non-perishable food and drinking water that will last a couple of days. Get extra ice and put it in plastic bags. This will help maintain the temperature in your refrigerator and freezer.

Set aside water. Fill the bathtub with water for toilets; a bucket in the bowl is all that’s needed for flushing. You can buy bottled water for drinking. Be prepared to cook outside, but don’t bring grills into the house.

Stock up on batteries for a battery-powered radio and flashlights, and have extra wood for fireplaces or wood stoves. Fill your car’s gas tank. 

Stay away from downed power lines.

You should avoid talking on the phone or watching TV during a lightning storm. Consider unplugging expensive items such as computers, televisions and refrigerators to avoid power surge damage, which can occur even if they are plugged into surge protectors.
