Approximately 3 to 6 inches of rain may fall in areas that already suffered devastating flash flooding last week, killing more than 100 people.

"Life-threatening flash flooding" is ongoing in Kerr and Gillespie Counties -- including the areas of Kerrville, Comfort, Ingram, Hunt, Mountain Home, Waltonia, Harper, Kerrville-Schreiner Park and Cypress Creek -- according to the National Weather Service.

The heavy showers have caused Flash Flood Warnings across Central Texas and prompted officials to close low-water crossings, roads and parks.
