Hurricane Nolo Strengthens Into Category 1 Storm, Set for Closest Pass Near Hawaii

Hurricane Nolo strengthened into a Category 1 storm on Friday as it churned south of Hawaii, prompting forecasters to warn of catastrophic, life-threatening flooding on the Big Island even though the storm itself is not expected to make direct landfall.

Current Position And Strength

As of the latest advisory, Nolo carried maximum sustained winds of 85 mph and was located roughly 220 miles south of Hawaii's South Point, about 410 miles south-southeast of Honolulu. The storm was moving slowly north-northeast at around 5 mph, giving it time to draw more energy from warm ocean waters before its closest approach to the islands.

The National Weather Service said Nolo is likely to continue strengthening into a Category 3 major hurricane on Friday night, right around the time it makes its nearest pass south of the Big Island on Saturday. While current forecast tracks keep the storm's center offshore, meteorologists stressed that a storm of this size does not need to make landfall to cause serious damage.

Rainfall And Flooding Risk

The bigger concern for residents is rainfall rather than wind. The National Hurricane Center expects the eastern and southern portions of the Big Island to see 15 to 30 inches of rain, with isolated pockets potentially receiving as much as 35 inches. In mountainous, steep terrain, that volume of rain raises the risk of catastrophic, life-threatening flooding and mudslides, conditions authorities are treating as seriously as they would a direct hit.

Watches And Warnings

A hurricane watch and tropical storm warning are currently in effect for the eastern, northern, southern and southeastern interior sections of the Big Island, along with the Kohala, Kona and summit regions. Maui County has been placed under a tropical storm watch as the outer bands of the system are expected to brush the neighboring island as well. Local emergency management officials have urged residents in flood-prone and low-lying areas to prepare for possible evacuation and to stock up on supplies ahead of the weekend.

What Comes Next

Forecasters caution that even small shifts in Nolo's track could change the intensity of impacts on different parts of the island chain, and residents are being told to monitor official updates through the weekend rather than rely on the current forecast track alone. Tourism-dependent local businesses across the Big Island and Maui are also watching the storm closely, given the potential for flight disruptions and road closures if the rainfall materialises as forecast.
