What happened

The episode as NWS EWX wrote it up.

Additional showers and thunderstorms continued to develop through the afternoon and into the evening of July 1 over the Kendall-Bexar-Comal County area. An additional rainfall of up to 10 inches fell during this period, with the rain continuing through the morning of July 2 over Comal County. This, added to the previous amounts, and in view of soils that were long since saturated, produced widespread flash flooding across the three counties. Damage was now becoming widespread to roads and bridges across the three counties.

The people who died

As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.

What these are

Flash Flood
Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
Flood
Flooding that develops more slowly than a flash flood: rivers leaving their banks, or water standing over land for an extended time.

After NWS Directive 10-1605, the rules offices file Storm Data by.
