Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

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.

Kerr County officials Tuesday appeared to dodge questions about how soon they were notified about deadly flash floods in central Texas and who was responsible for immediate response efforts, as law enforcement warned the death toll from the flooding will likely rise.
