"Rescuers searched for a 6-year-old boy and a hiker missing on Wednesday after flash floods in southern Utah killed at least 18 people in a national park and a small town on the Arizona border.
In a double tragedy for the state, a wall of water and debris swept through Hildale, Utah, on Monday afternoon, sweeping away two cars and killing at least a dozen people, while at about the same time flooding killed six people and left one missing in Zion National Park.
More bad weather and the threat of further floods have hampered rescue operations in the park, county officials said."
