A slow-moving storm set off flood warnings in several regions of the Hill Country, including Kerr County, the area hit hardest by the July 4 floods.

Parts of Central Texas are under yet another flood watch this weekend. The impacted areas are the same as those hit by the July 4 deadly floods.

Through the rest of the evening on Sunday, the NWS is predicting a level two of four (slight) risk of storms across the majority of South Central Texas. Rainfall amounts of two to four inches is expected, while some areas could see pockets of nine to 12 inches of rainfall in certain regions.
