It is such a nightmare. My hubby is from California and is not familiar with 'flash' floods that produce a wall of water. I grew up in Sanderson Tx and a 'flash' flood came through there in the 60s and nearly washed it away. That kind of flooding takes people completely by surprise. My heart goes out to all of the people who were caught in that situation. Will continue praying for the families that have suffered such great tragedy.
