If she stays, make sure she stays put and doesn’t drive anywhere during the storm, there could be significant flash flooding and falling trees. Also make sure she has at least five gallons of bottled water and some canned/ready to eat food such as soup or spam or bread. Also good to fill up buckets and pots with water for flushing in case water pressure goes out due to lack of electricity to pump it up into water towers. A top-loading washing machine is great for such water storage as well - fill it and turn it off. Also, a gallon of unscented bleach and cloth for straining can be used to disinfect tap water.
Water for flushing toilets, etc. becomes pretty dear in a protracted power outage. Fill the bathtub and possibly even a few sinks for this purpose. Conserve the clean water for drinking, cooking and bathing. Gas grill is very handy, cold canned food gets old quick. Ice for refrigerated and frozen foods so they won’t spoil.
I sent your entire post to her. Thanks
Fill the bathtub. Then, all you need is a 1-gallon bucket to "flush" the toilet.
Use your other containers to store drinking water.
