Update: Flood advisory canceled for northeast, central portions of Kauaʻi

Update at 2:55 p.m. Jan. 9: The National Weather Service in Honolulu reports that stream gauges show a downward trend in water flow and the threat of heavy showers has ended.

Therefore, the flood advisory that was previously in effect for northeast and central portions of Kauaʻi until 3:30 p.m. today was canceled.

Update at 12:50 p.m. Jan. 9: A new flood advisory is now in effect until 3:30 p.m. for northeast and central portions of Kauaʻi as the National Weather Service is forecasting minor flooding on roads and in poor drainage areas and streams because of excessive rainfall.

Rain gauge reports at 12:26 p.m. indicated a sharp increase in rainfall over the Wainiha River during the past hour, and an increase of runoff is expected during the next few hours over north Kauaʻi because of heavy rainfall over Mt. Waialeale during the past few hours.

Some locations that will experience flooding include Kapa’a, Princeville, Kīlauea, Hanalei, North Fork Wailua Trails, Wainiha, Wailua Homesteads, Moloaʻa, Hāʻena, Alakaʻi Swamp Trails, Wailua, Anahola, Nā Pali State Park, Kalihiwai, Wailua River State Park and Keālia.

National Weather Service forecasters advise the public to stay away from streams, drainage ditches and low-lying areas prone to flooding.

The statewide area forecast discussion at just before 10 a.m. today said trade winds will steadily return across the state today, but an upper level disturbance will continue to produce unsettled weather conditions through Friday.

Showers will be focused over windward and mauka areas, with pockets of heavy showers possible through tonight and continuing over the eastern half of the state through tomorrow.

Generally fair weather is expected during the weekend, but some showery weather conditions could linger around windward Big Island and east Maui through Saturday.

Original post at 8:50 a.m. Jan. 9: Most of Kauaʻi is under a flood advisory until 9:15 a.m. today as heavy rains falls over the north and east parts of the island.

The National Weather Service in Honolulu says minor flooding of roads and in poor drainage areas and streams is to be expected as rain falls at up to 2 incheas an hour, with satellite indicating earlier this morning the heaviest located the northeast portion of the island near Moloaʻa and Anahola.

Additional heavy showers will be possible throughout the morning.

Some locations that will experience flooding include Līhuʻe, Kapaʻa, Princeville, Kīlauea, North Fork Wailua Trails, Hanalei, Wainiha, Wailua Homesteads, Alakaʻi Swamp Trails, Hāʻena, Moloaʻa, Wailua, Anahola, Nā Pali State Park, Kōkeʻe State Park, Kalihiwai, Wailua River State Park, Keālia, Hanamāʻulu and Waimea Canyon State Park.

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

A statewide area forecast discussion from early this morning reports that a weakening front over the Kauaʻi Channel continues to produce showers, mainly impacting Oahu.

Lingering moisture combined with an upper disturbance moving over the state will increase rainfall chances statewide today through Friday, along with the chance for thunderstorms.

As trade winds gradually return today, the focus of rainfall will shift to windward and mauka areas through early next week.
