Hawaii has been struck by severe flash floods, particularly in areas north of Honolulu, leading to widespread inundation of streets and homes. The National Weather Service reported significant rainfall, with parts of Oahu receiving 8 to 12 inches overnight, and the island's highest peak, Kaala, recording nearly 16 inches. The dire situation has resulted in evacuation orders for thousands of residents due to the imminent risk of failure of the 120-year-old Wahiawa dam. Emergency sirens were activated, and over 230 people have been rescued from the floodwaters.
