You live in a mobile home. No matter how well you tie it down, it is unsafe. If you do NOT want to leave your home during a storm, you can stay. But remember, that you will be entirely on your own. No calls for help will be answered during the storm, and if you decide to go out after the storm and you are in a devastated area you may not be able to return to your home, so make sure you have everything you will need to survive for at least two weeks after the storm passes.
Winds are much stronger at higher elevations.
For example, Andrew was about 110 mph at ground level, but 175 to 180 mph just 10 stories up. You know your building is unsafe and you can't repair it. You use life-support equipment that requires electricity. Find out which shelters are closest to you. Evacuation routes are marked along the highways, unmarked roadways can become impassable very early on, so stick to the marked evacuation routes.
