Hawaii on high alert as worst flooding in two decades prompts mass evacuations

A Kona Low storm dumped extreme rainfall across Oahu and Maui, triggering a statewide flood watch and mass evacuations—more than 230 people rescued and thousands displaced—as authorities warn that saturated ground means even less rain could trigger dangerous floods; a dam near Honolulu is at risk of collapse, and damages could exceed $1 billion, marking Hawaii’s worst flood in 20 years.
