Heavy Rain and Flash Flooding Impact Hawaiian Islands

Heavy rainfall and flash flooding have caused road closures and emergency warnings across several Hawaiian islands. On Kauai, the National Weather Service extended a flash flood warning until 8:45 p.m. following reports of rain falling at rates of 1 to 2 inches per hour. According to the Honolulu Star-Advertiser, Doppler radar and rain gauges indicated heavy rain across the entire island by 5:08 p.m. The flooding resulted in the closure of Kuhio Highway near the Hanalei Bridge. Officials also observed a rapid rise in water levels along the South Fork of the Wailua River. In response to the conditions, Kauai County opened a community-led refuge area at Hale Halawai in Hanalei. County officials noted that this site is an evacuation option of last resort and does not provide medical staff, bedding, food, or water. On Oahu, a flood advisory was issued until 10 p.m. due to rainfall of up to 3 inches over the Koolau mountains. Hawaii News Now reported that minor flooding was expected in several windward areas, including Kailua, Kaneohe, and Manoa. The National Weather Service indicated that the weather system affecting Kauai and Niihau may impact Oahu overnight. Forecasts suggest that a front moving through the island chain late Sunday into Monday will bring drier air and breezy northeasterly trades. Separately, Maui County recently dealt with its own weather crisis. According to Maui Now, a flood watch and flash flood warning for East Maui expired the evening of October 29, 2026. The period of heavy rain caused rockfalls, mudslides, downed trees, and flash flooding in parts of ʻĪao Valley and East Maui. The Maui Emergency Management Agency had previously issued an evacuation warning for the Kīpahulu District of Haleakalā National Park, which was lifted at 5:13 p.m. on October 29. A temporary evacuation point at Helene Hall in Hāna was used by approximately five visitors before closing at 6 p.m. that evening. The heavy rain also led to the closure of various municipal facilities, including the Waiehu Municipal Golf Course and several baseball and tennis fields across the island. --- HOT covers what Americans are searching for most right now.
