State and local officials in Texas have come under scrutiny over the lack of sirens in place to warn people of impending flash flooding.

The death toll in the July 4 Central Texas flooding rose to 103 on Friday as the search continued for those still missing.

The National Weather Service began sending flash flood warnings that should have triggered cellphone alerts a little after 1 a.m., while local officials began posting on Facebook about four hours later.
