Parts of southern Texas are at risk of “significant to locally catastrophic flash flooding” as slow-moving storms dump heavy rain on the region through Thursday.

Slow-moving storms drenched much of southern Texas with more heavy rain on Wednesday, prompting warnings to evacuate flooded areas after downpours washed out roads and farmland and led to dozens of high-water rescues across the region.

The National Weather Service placed the city of Boerne and Kendall County, as well as Medina County, under a Flash Flood Emergency Wednesday afternoon.

A Flood Watch remains in effect for most of Central Texas, including the Austin metro, as heavy rain falls across the area.
