HONOLULU — The City and County of Honolulu is urging residents and visitors to remain vigilant as a severe weather system continues to impact Oʻahu, bringing the potential for heavy rain, damaging winds, and flooding across the island.

Weather Forecast

According to the National Weather Service, a deepening low-pressure system west of the state will bring increasingly unstable weather conditions through the remainder of the week. The system is expected to draw up tropical moisture, resulting in periods of heavy rainfall, thunderstorms, and an elevated risk of flooding.

The heaviest rainfall is currently forecast from late Thursday night through Friday as a frontal boundary intensifies just west of Oʻahu. While a brief break in the weather is possible on Saturday, additional rounds of rain and unsettled conditions may continue into next week.

A Flood Watch remains in effect for Oʻahu through 6 p.m. on Friday, April 10.

High Wind Warning in Effect

The National Weather Service has also issued a High Wind Warning for Oʻahu from 6 a.m. Thursday, April 9 through 6 a.m. Friday, April 10.

South winds of 20 to 30 miles per hour with gusts up to 60 miles per hour are expected, particularly across Central Oʻahu, the North Shore, and higher elevations.

These conditions may result in downed trees, power outages, and damage to structures. Residents are advised to secure loose outdoor items and prepare for possible disruptions.
