Flash floods last week in Texas caused the Guadalupe River to rise dramatically, reaching three stories high in just two hours.

Here's what to know about the deadly flooding, the colossal weather system that drove it and ongoing efforts to identify victims.

At least 111 people have been killed and a further 173 are still missing after catastrophic flash flooding swept through Central Texas.

As heavy rains led to heartbreaking losses at a Texas girls camp, other parts of the state were swamped over the July 4 weekend.

Heavy rain poured over parts of central Texas, dumping more than a month's worth of rain for places like San Angelo.
