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.

Five days after deadly floods struck central Texas, search and rescue teams are continuing to probe debris for those still missing.
