The National Weather Service has issued a flood watch for south central Texas, a week after the area was devastated by deadly flash floods.
The watch, which takes effect at 10 a.m. Saturday and continues through Sunday evening, warns of locally heavy rainfall that could trigger more flash flooding. One to three inches of rainfall is expected, with isolated amounts reaching up to six inches possible.
"A weak upper level system approaching from the north combined with above normal moisture will result in locally heavy rainfall across the region today and Sunday," the weather service warns. "This rainfall along with saturated soils will lead to rapid runoff."
This excessive runoff could prompt flooding in rivers, creeks, streams and other low-lying and flood-prone locations, according to the National Weather Service.

Warning vs watch: What is a flash flood watch?
A flood watch is issued when conditions are favorable for flooding, according to the NWS. It doesn't guarantee flooding will occur, but it means flooding is possible.
A flash flood warning is issued when a flash flood is imminent or already happening, USA TODAY reported. If you’re in a flood-prone area during a flash flood warning, move to higher ground immediately.
Flash floods can develop within six hours of heavy rain, dam or levee failure. They can uproot trees, destroy buildings and bridges and trigger mudslides — sometimes with water rising over 40 feet as witnessed along the Guadalupe River flooding, which rose by 40 feet in less than two hours.
Flash floods can even occur in areas that aren't receiving rain, the NWS warns.
