Several families evacuated flooded homes after daybreak on the 18th, with one report stating that up to 60 homes were surrounded by water, with water reaching into a number them.

Tropical moisture flowing into Deep South Texas well behind Tropical Depression Bill, was given a boost by a leftover upper level trough and boundaries from prior storms across the South Texas Brush Country on June 17th/early June 18th to trigger a band of repeating thunderstorms across central and north Jim Hogg County. Rainfall estimated ranged from 6 to 12 inches across northern Jim Hogg County. This created flash flooding in Hebbronville between 630 pm and 10 pm on the 17th. The rains eased toward the Upper Valley and a persistent south to north band of torrential rains lined up from near Muniz to San Carlos to Faysville between 11 pm and midnight, and continued developing southward to Pharr/Alamo/San Juan through 1 am on the 18th. An estimated 2 to 4 inches of rain fell in little more than an hour and created flash flooding in the colonia of San Carlos, an area known for poor drainage.
