The official tally of storm-related deaths across Texas rose to 131 on Monday as authorities warned of yet another round of heavy rains 10 days after a Hill Country flash flood that transformed the Guadalupe River into a killer torrent.

As in Friday’s flooding, in 1987, five to 10 inches of rain fell in the upper headwaters of the Guadalupe River basin. In Hunt, Texas, where the Guadalupe River forks, over seven inches had fallen since Thursday afternoon, which was the highest total at the site since the early 1990s.
