More than 100 people were killed in flash floods in Texas over the weekend, with survivors saying they did not receive any emergency warnings, The Associated Press (AP) reported Monday.

Although the National Weather Service sent out a series of warnings, locals insisted no one saw the floods coming.

"The National Weather Service did get forecasts that provided very useful warnings, the day before they were talking about flash floods," University of Washington Atmospheric Sciences Professor Cliff Mass explained on "The John Curley Show." "Hours before the major disaster happened, they put out extremely strong warnings of the potential for flash flooding."
