The death toll, as of Monday at 1 p.m., of 90 fatalities, makes the Central Texas flash floods on July 4 the second-deadliest flood disaster in Texas history.The Hill Country is notorious for flash flooding,

In 1987, sudden and intense rainfall caused the river to surge at an unprecedented rate in mid-July, leading to a tragedy that killed 10 campers at Pot O' Gold Christian Camp, a summer camp near Comfort, Texas. The campers drowned when their bus attempted to evacuate them and was overtaken by floodwater.

The deadly floods in Central Texas were caused by extremely heavy rain. Climate change is causing even more rain to fall during the heaviest storms.
