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

Ground search operations were suspended Sunday in Kerr County, Texas, where crews have continued to look for those still lost after catastrophic July 4 flooding.

"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.
