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

The Flood Watch in effect for parts of the southern Plains, including much of Oklahoma and Texas, was expanded southeast this morning to encompass areas that were hit hard by catastrophic and deadly flash flooding last weekend, including Kerr, Travis and Burnet Counties.

The NWS Fort Worth TX released an updated flash flood warning at 9:09 p.m. on Saturday in effect until Sunday at midnight. The warning is for Collin, Dallas and Denton counties.

Flash floods in Texas have killed at least 107 people over the Fourth of July weekend, with more than 160 still missing.

KHOU 11 Meteorologist Pat Cavlin says it's impossible to determine exactly where the heaviest of rain will fall, but everyone in risky areas should stay aware.

This part of Texas Hill Country is known for flash floods. Why were so many people caught off guard when the river turned violent?

This is false. It is not possible that cloud seeding generated the floods, according to experts, as the process can only produce limited precipitation using clouds that already exist.

In the wake of disaster, people are relying on the volunteer fire department, the backbone of the Hill Country.

More than 111 people have died across six counties after flash flooding from heavy rain began affecting the state last week.

Young campers and a dad saving his family were among the dozens killed in the historic flash floods that tore through central Texas over the holiday weekend.
