Flood advisory in effect for Kaʻū District of Big Island, but canceled for Hāmākua Coast

The National Weather Service said a flood advisory is in effect for the Kaʻū District through 7:15 a.m. Thursday.

But the flood advisory has been cancelled for the Hāmākua Coast on the east side of the island.

A flood watch also remains in effect through Friday morning for the entire island because of the possibility of heavy rainfall from the remnants of what was Tropical Storm Norbert.

National Weather Service forecasters in Honolulu report that flooding caused by excessive rainfall is expected, including minor flooding on roads as well as in poor drainage areas and streams.

At 4:10 a.m., Doppler radar and automated rain gauges indicated heavy rain over the Ka’u district from Naalehu to Hawai’i Volcanoes National Park. Minor flooding is ongoing or expected to
begin shortly in the advisory area. Rain was falling at a rate of 1 to 2 inches per hour.

Some locations that will experience flooding include Pāhala, Wood Valley, Punaluʻu Beach, Kawa Flats, Hawaii Volcanoes National Park, Nāʻālehu, Waiʻōhinu and Discovery Harbour.

The public is advised to stay away from streams, drainage ditches and low-lying areas prone to flooding.
