Just tell her to fill an ice chest tonight with ice, in case the electricity goes out. And have a barbecue ready to cook the meat that might defrost from her freezer. Then flashlights, hurricane candles in glass, something to read by candlelight and plenty of bottled water and canned foods for a few days, in case she gets shut in. I like to have a bottle of something alcoholic to sip, but drinking through hurricanes is a Louisiana solution. i don't know if it's in favor here.
