You can be stranded or trapped by rapidly rising floodwaters. The depth of water is not obvious. Seek higher ground, rapidly rising water may engulf the vehicle and sweep it downstream with potential tragic consequences. Stay away from open windows, metal pipes, fireplaces, sinks, and electrical appliances. You may want to avoid talking on the telephone.
Lightning has been know to hit telephone lines and shock people on the phone nearby.
If you are caught outdoors, do not stand under a tall, isolated tree or telephone pole. Seek shelter under a thick growth of small trees. Do not project above the landscape, go to a low place, such as a ravine or valley. Get away from the beach and open water. If you are swimming or boating, come in off the water immediately.
