The following counties and areas in Texas currently have a flood warning in place: Guadalupe River near Bloomington affecting Victoria, Refugio and Calhoun counties. Neches River near Diboll, affecting Angelina, Polk and Trinity counties. Rio Grande, Big Bend National Park, affecting Brewster County.

Meteorologists say incredible amounts of moisture in the air fueled a storm that moved slowly over central Texas, creating conditions for fatal flash floods.

At least 24 people have died and about 20 children are missing after a catastrophic flash flood in Texas. The Guadalupe River that runs through Hill Country in central south Texas rose by 26ft (8 metres) in just 45 minutes in the early hours of Friday, according to officials, bursting its banks and damaging roads and property.
