Local officials in Texas on Tuesday said they were unable to answer key questions about how prepared they were for the deadly flooding that struck the area on Friday, including how and when the county emergency manager responded.

Emergency responders kept hope alive as they combed through fallen trees and other debris that littered the hard-hit central Texas communities on the fifth day after devastating floods killed more than 100.

At least 13 fatalities were reported Friday as devastating floods slammed Texas' Hill Country with water rescues taking place along the Guadalupe River, officials said.
