Families stuck for hours. The weather triggering mandatory evacuations. The fear, hillsides scorched by record-setting fires could crumble and turn into deadly mudslides. Part of one home already pushed off its foundation in Encino. To the north, 50-mile-per-hour winds whipping in whiteout conditions. This plane, stuck in a wheelie, the tail covered in more than 16 inches of snow. David, tonight we are under a flash flood watch.
