The Fourth of July flooding had an outsized effect not just on the Hill Country but also on rain-starved Texas cities like San Antonio and Austin.

Flash floods in Texas last week killed at least 121 people and left more than 170 missing. Farmers are now working to assess damage to their properties.

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

As a climate scientist who calls Texas home, I can tell you that the Hill Country of Texas is no stranger to flooding. Meteorologists often refer to it as “Flash Flood Alley” because of its steep terrain, shallow soils, and its history of sudden and intense rainfall.

According to local authorities, at least 109 people died on July 4 and 5, most of which were swept up in floodwaters from campgrounds along the Guadalupe River. That’s just shy of the 118 deaths reported as a result of Hurricane Rita in 2005.

NASA’s high-altitude WB-57 aircraft took off from Ellington Field Joint Reserve Base in Houston on Tuesday, and will conduct aerial surveys using its DyNAMITE (Day/Night Airborne Motion Imager for Terrestrial Environments) sensor.

Officials in Texas are facing mounting questions about whether they did enough to get people out of harm’s way before a flash flood swept down the Guadalupe River and killed more than 100 people, including at least 27 children and counselors at an all-girls Christian camp.

Some people online suggested cloud seeding conducted by the company Rainmaker Technology Corporation was to blame for deadly flooding in Texas.
