Thanks, DB. That was my concern
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.
