What happened

The episode as NWS EWX wrote it up.

Moderate to heavy rainfall continued through much of the morning on Sunday the 23rd, producing widespread flash flooding over secondary roads and over low water crossings. Flooding also developed over much of Kerr County as the heavy rain forced the Guadalupe River out of banks from Hunt eastward to near Kerrville.Poor visibility in heavy rain caused a woman to drive into a flooded low-water crossing about 8 miles north of the city of Uvalde near 8:30 am Sunday. She and her 13 month-old son were swept into rain- swollen Indian Creek for several minutes, then deposited suddenly by the raging waters onto a patch of dry land. Firefighters found her clutching a tree with one hand and her child with the other. They were taken to a nearby hospital, treated and released.Rain continued over a large part of South Central Texas into the afternoon of Sunday, August 23rd, with the heaviest rainfall over the western Hill Country and the Edwards Plateau. Rainfall amounts were highest in northern Val Verde County, with general 4 to 6 inches totals. Flooding had threated homes along San Felipe Creek in Del Rio through the morning. And, in spite of increasingly strong warnings and requests for evacuation of the area, as well as attempts by Police, Sheriff's Deputies and Firefighters to move residents out of San Felipe Creek, most refused to move.
