UPDATE: 8:40 p.m

A flash flood warning has been issued for the island of Hawaii until 10:45 p.m. as heavy rain continues and three shelters have been opened.

“At 7:39 p.m., radar and automatic rain gauges indicated heavy rain primarily over the windward, southeastern and interior portions of the Big Island. “Rain was falling at a rate of up to 3 inches per hour,” the National Weather Service warning said. “This is resulting in significant rises in stream and river levels, with levels on Honolii Stream and Wailuku River exceeding the minor flood level of 15 feet and 18 feet, respectively. Flash flooding is ongoing or expected to begin shortly.”

Areas that will experience flash flooding include Hilo, Kailua-Kona, Hawaiian Paradise Park, Captain Cook, Waikoloa Village, Kapaau, Honokaa, Pohakuloa Training Area, Pohakuloa Camp, Volcano, Wood Valley, Glenwood, Honaunau, Hawaii Volcanoes National Park, Honalo, Mountain View, Kainaliu, Kealakekua and Puuanahulu.

Evacuation shelters have opened at the Kau District/Robert N. Herkes Gym, Keaau Armory and Naalehu Community Center.

A flood watch until Tuesday afternoon covers the island and Maui.

“Low tropical moisture associated with a low pressure trough will continue to move westward across the state through Tuesday,” flood watch officials said. “Combined with an aloft disturbance, the threat of heavy rain, flash flooding and the possibility of some thunderstorms remains, particularly over windward portions of the Big Island and Maui.”

This leads to a significant increase in water levels in streams and rivers.

PREVIOUS COVERAGE

A flood warning remains in effect for the islands of Maui and Hawaii until Tuesday. The National Weather Service warns of the risk of flash flooding, heavy surf and dangerous conditions for small boats.

Weather officials say heavy rainfall is expected, primarily affecting windward areas of Maui and Hawaii Island due to the influx of tropical moisture. This could lead to flash flooding in low lying areas and urban zones due to increased runoff. Residents and visitors are advised to avoid roads at risk of flooding and to monitor local weather forecasts.

A high surf warning remains in effect today until 6:00 p.m. for the north and west shores of Niihau, Kauai, Oahu, Molokai and the north shore of Maui. Waves reaching 12 to 16 feet on the north shore and 8 to 12 feet on the west coast create dangerous swimming conditions. Beachgoers are urged to follow the guidance of marine safety authorities.

A small boat advisory is in effect for the windward waters of Maui County, Maalaea Bay and the channels surrounding Hawaii Island. East winds of up to 25 knots will create challenging conditions until early Tuesday morning. Sailors, especially those on smaller ships, are warned not to venture out.

Meteorologists expect locally heavy rain and thunderstorms on Maui and the island of Hawaii through Tuesday. However, a cold front will approach the islands on Wednesday, but will stall and dissipate as a new high forms to the north. The shift is expected to bring wetter trade winds and breezy to breezy conditions through the end of the week.
