Flood water can be deceptive! It is difficult to determine the depth or speed of floodwater.
Do not attempt to cross floodwater in an automobile
Even shallow water can disable or carry away heavy vehicles such as trucks.
If you do find yourself in a automobile which is being carried away by floodwater, abandon it immediately - It is a lost cause.
Do not directly touch floodwater if possible. Floodwater is rarely pure and may contain contaminants such as sewage, chemicals, electical hazards, or sharp debris. Because flood water is often murky, you may not be able to truly see what hazards are in the water.
