Central Texas faces severe thunderstorms, with meteorologists predicting rainfall rates of 2 to 4 inches per hour. There is a threat to serious flash flooding.

Flood watch in effect through 7 PM Sunday. Locally heavy rainfall could trigger flash flooding across portions of south-central Texas. A weak upper-level system combined with above-normal moisture may lead to heavy localized rainfall and rapid runoff.

Some regions in the mid-Atlantic are also facing risks of flooding. On Sunday, Tropical Storm Chantal flooded parts of North Carolina, where more than 10 inches of rain fell near the Chapel Hill area. The Haw River, near Bynum, North Carolina, crested to nearly 22 feet, the highest crest on record there, as a result of those heavy rains.

Kerr County failed to secure a warning system, even as local officials remained aware of the risks and as billions of dollars were available for similar projects.
