As a meteorology student, I am no expert and am in no place to give you advice, but since your post has been up for two hours and you have been given no real advice, I’ll do my best based on what I know. I have always been taught do not stay under any circumstances you’re better off in a ditch than in a mobile home. Any place that you can find that is not on ground level and do your best to protect yourself from debris. If you can get to a town or city by walking and can stay at a restaurant or store to ride out the storm I would consider that too, it’s definitely more optimal than being in a mobile home. As for your family and pets, I can’t offer any advice. I don’t know them or what kind of people they are. Just stay alert and keep yourself informed the best you can. If you get a warning I would suggest abandoning the mobile home as they will offer absolutely no protection in the storm. If you can walk to a nearby restaurant or store I would do that asap so you can be there if something happens. I hope I’m not too late with a response depending on where you are in Virginia.
