As much as 20in (500mm) of rain was reported in parts of Texas as storms hit the state, sending devastating torrents of water down river valleys.

Camp Mystic in Kerr County says Monday morning that it is “grieving the loss” of 27 campers and counselors as the search continues for victims of the disaster. The flooding sent a wall of water through the century-old summer camp Friday.

National Weather Service has issued a flood watch for the areas of Central Texas hit most by the deadly flooding over Fourth of July weekend.
