The Guadalupe River basin had drawn July Fourth weekend revelers to its youth and family campgrounds, RV parks and apartment rentals. But this basin was also prone to flash flooding – and soon an entire summer’s worth of rain would begin to fall.

Parts of the state devastated by flash floods that left at least 82 dead were braced for more heavy rains as forecasters extended flood warnings through Monday evening.

With more rain on the way, the risk of life-threatening flooding was still high in central Texas on Monday even as crews search urgently for the missing following a holiday weekend deluge that killed at least 82 people, including children at summer camps. Officials said the death toll was sure to rise.
