Earlier in the day the NWS sent out a warning about the dangers of flash flooding. They say 6 inches of fast moving water can knock over and carry away an adult and 12 inches of fast moving water can carry away a small car. When you've got 18 to 24 inches of fast moving water, that can carry away most large SUVs, vans and trucks.
