More than 160 people are known to be missing after devastating floods swept through Central Texas over the July Fourth weekend, Texas Gov. Greg Abbott (R) said Tuesday — raising the possibility that the death toll could surpass 200 in what is already one of the deadliest flood events in the past five decades.

Meanwhile, Texas authorities have pledged to continue search and rescue operations until every missing person is found.

The National Weather Service issued a flash flood warning in Nashville as strong storms are expected to bring downpour.

Thunderstorms could cluster Tuesday afternoon, resulting in torrential rain for certain areas over a short period of time.
