What the National Weather Service wrote

Prolonged heavy rainfall flooded roads across Brown County since September and this new flooding damaged some roads and bridges in the county.

The wider storm

An upper level low pressure system remained park across Baja California through October 17. This feature interacted with plenty of moisture and resulted in periods of very heavy rain from October 15 through the 17.

Widespread flooding developed across the area and many lakes and rivers rose above flood stage and resulted in widespread flooding. Millions of dollars of damage was done to roads and county infrastructure.

Johnson Fork Creek rose high enough that it caused some water to overflow onto one of the lanes on Interstate 10. Interstate 10 had to be closed. The Clear Fork on the Brazos River near Fort Griffin rose to 36.18 feet on October 15; The Llano River at Mason rose to 32.89 foot on October 16; Colorado River near San Saba rose to 32.53 feet on October 17; Colorado River near Ballinger rose to 22.97 feet on October 17; and the San Saba River at San Saba rose to 28.54 inches on October 16.
