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

Heavy rain poured over parts of central Texas, dumping more than a month's worth of rain for places like San Angelo.

Sources have said FEMA wasn’t authorized to launch search and rescue teams until 72 hours after flooding began.

Heavy rains fell quickly in the predawn hours of Friday in the Texas Hill Country, causing the Guadalupe River to rise 26 feet in just 45 minutes.

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.

The heavy rain that turned a river in Texas into a raging wall of water was fueled by unique atmospheric conditions, according to meteorologists and climate scientists.

"There has been a lot of misinformation flying around lately, so let me clarify: the Texas Department of Agriculture has absolutely no connection to cloud seeding or any form of weather modification," Miller said in a statement.

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.

In the wake of the Texas flooding disaster, parts of Ohio could also experience floods this week. Here are the worst recorded floods in Ohio history.

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,

Flash floods surged through in the middle of the night, but many local officials appeared unaware of the unfolding catastrophe, initially leaving people near the river on their own.
