KERRVILLE, Texas, July 8 (Reuters) - The death toll from the July Fourth flash flood that ravaged a swath of central Texas Hill Country rose on Tuesday to at least 109, many of them children, as search teams pressed on through mounds of mud-encrusted debris looking for scores of people still missing.

Fears grew Wednesday that the death toll of 110 in the Texas floods could still surge as hopes fade of finding survivors among the many reported still missing several days after the disaster.
