Scenes of devastation stretched along Texas' Guadalupe River Saturday morning the day after a "deadly flood wave" pushed a 20-foot surge of water several miles down the river, leaving at least 24 dead and dozens more still missing,

The slow-moving storm stuck over central Texas is expected to bring more rain Saturday, with the potential for pockets of heavy downpours and more flooding, said Jason Runyen, of the National Weather Service. The threat could linger overnight and into Sunday morning, he said.
