Senate Democratic Leader Chuck Schumer asked the Department of Commerce's acting inspector general Monday to probe whether staffing vacancies at the NWS's San Antonio office contributed to "delays, gaps, or diminished accuracy" in forecasting the flooding. He asked the watchdog to scrutinize the office's communications with Kerr County officials.

NWS says Flash Flood Warnings were issued on July 3 and early July 4 in Central Texas, giving more than three hours of warning.

As searchers continue to look for victims in the deadly flash flooding in Texas, officials are answering questions about the weather forecasts ahead of and during the storm.
