The deaths of scores of people from flash flooding in the state of Texas have raised questions about whether cuts to the U.S. National Weather Service impacted weather forecasting. U.S. President Donald Trump has rejected that suggestion.

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

The U.S. Senate's top Democrat on Monday asked a government watchdog to investigate whether cuts at the National Weather Service affected the forecasting agency's response to catastrophic flooding in Central Texas.
