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

White House press secretary Karoline Leavitt later began her briefing on the offensive, calling out those who've questioned whether federal cuts to the NWS impacted staffing levels or forecasting abilities as the tragedy unfolded.

Many warnings from the National Weather Service went out to Kerr County, Texas, but the area wasn't equipped with sirens to wake residents up.

After deadly floodwaters swept through Central Texas, there are questions about the timeline of weather alerts and possible gaps in the warning system.

Emergency responders continue to search for missing people and local police said efforts have been slowed by "sightseers who are making things worse."
