Residents across Oahu face extensive cleanup, displaced housing, and health risks from volcanic mud coating structures.

AI Summary

Hawaii's worst flooding in two decades has swept across Oahu, damaging hundreds of homes, schools, and a hospital while coating structures in thick volcanic mud. The deluge swept homes off foundations and floated cars from driveways, with damage expected to exceed $1 billion as residents face an extensive cleanup. The flooding has caused immediate secondary damage, with fresh downpours triggering additional inundation on Oahu's south side even as residents on the North Shore began assessing losses. The volcanic mud coating—a distinctive hazard of Hawaii's geology—complicates cleanup efforts and poses health risks as residents work to restore their homes and community infrastructure.
