If you still insist on leaving, do it early.
People can die on the roads that way, officials say.
Some people must leave their homes because they live in evacuation zones. If you're not in an evacuation zone, the best thing may be to batten down in your well-prepared home and ride out the storm there. Finish battening down your home anyway. Move patio furniture, hanging plants and gas grills inside. If your home is likely to sustain damage from rising water, raise valuables and expensive furniture off the floor as best you can.
