"Let's put an end to the conspiracy theories and stop blaming others," Texas Agriculture Commissioner Sid Miller said in a statement.

Texas leads the country in flood deaths. Steep hills, shallow soils and a fault zone have made Hill Country, also called "flash flood alley," one of the state's most dangerous regions.

Texas Hill Country is no stranger to extreme flooding. In the rugged, rolling terrain it’s known for, heavy rains collect quickly in its shallow streams and rivers that can burst into torrents like the deadly flood wave that swept along the Guadalupe River on July 4.

The Gulf, which borders Texas, has become significantly warmer in recent years due to climate change, Swain explained. This results in a very warm body of water that produces a lot of evaporation, releasing more tropical moisture into the air than seen historically.

Some regions in the mid-Atlantic are also facing risks of flooding. On Sunday, Tropical Storm Chantal flooded parts of North Carolina, where more than 10 inches of rain fell near the Chapel Hill area. The Haw River, near Bynum, North Carolina, crested to nearly 22 feet, the highest crest on record there, as a result of those heavy rains.

After a devastating holiday weekend that left dozens dead and many still missing, Central Texas is bracing for more rain. Forecasters warn that additional storms this week could exacerbate already hazardous flood conditions,

The White House is defending the National Weather Service and accusing some Democrats of playing politics in the wake of devastating floods in Texas.

There was little indication of how torrential the Texas downpours would become before dawn. At least 27 people were killed, many of them children at Camp Mystic.

Federal forecasters issued their first flood warning at 1:14 a.m. on July 4. Local officials haven’t shed light on when they saw the warnings or whether they saw them in time to take action.
