UVALDE, Texas (AP) — Dangerous flooding in Texas has intensified after days of pounding rain, sending emergency crews scrambling to rescue people from high water before sunrise Thursday and setting off urgent warnings from forecasters: “Move to higher ground now!”

The National Weather Service in San Antonio said a “large and deadly flood wave” was barreling down the same river devastated by floods a year ago when two dozen children and counselors were killed at Camp Mystic.
