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.

Water levels rose again in central Texas as rain pounded the areas still recovering from last week's deadly floods.

In Kerrville, authorities went door-to-door to some homes early Sunday to alert people that flooding was again possible.
