The death toll in Kerr County crept up to 87 on Tuesday as search and rescue efforts continued in flood-ravaged central Texas, according to officials in the county worst hit by the disaster, which has killed more than 100 people.

A massive Texas search and cleanup effort was set to enter its fifth day Tuesday in response to Guadalupe River flooding that surged through the area on July 4.

The death toll in the central Texas floods has risen to over 100. Officials say the majority of the deaths were in Kerr County. Search and recovery crews there are working through masses of downed trees and other debris.
