At least 161 are still unaccounted for after the July Fourth floods that saw the waters of the Guadalupe rise to historic levels in Central Texas, officials with Kerr County said Friday. Authorities have confirmed 103 deaths, 36 of whom are children.

Recordings provided to CBS News showed first responders asking for an emergency alert to be sent, but dispatchers delayed because they needed special authorization.

The search for more than 160 people still unaccounted for in flood-ravaged central Texas has been temporarily halted due to ongoing rainfall in the region. Officials say the majority of the nearly 130 confirmed deaths occurred over the Fourth of July weekend in Kerr County, one of the areas hardest hit by the historic flooding.

In the days after the devastating flood that killed dozens in Central Texas, local officials have deflected direct questions about preparations and warnings in advance of the storm that struck July Fourth.

In the last nine years, federal funding for a system has been denied to the county as it contends with a tax base hostile to government overspending.

The number of people reported missing in Kerr County, Texas, as a result of last week’s flash floods continues to soar. Authorities say search teams combing through the debris and destruction there are looking for more than 160 people who disappeared in the raging waters.
