The Central Pacific Hurricane Center began issuing advisories at 5 am Thursday 8/22 on what would eventually become Hurricane Hone. Hone was the first named storm to develop in the central Pacific basin since Ema in 2019 (full list of Central North Pacific Names). A Tropical Storm Watch was issued for Hawaii County at 5 pm on Thursday 8/22, which was then upgraded to a Tropical Storm Warning at 5 pm on Friday 8/23. The Tropical Storm Warning was then canceled at 2 pm on Sunday 8/25. Before Hone, the last Tropical Storm Warning for Hawaii County (or any county in the state) was for Tropical Storm Calvin in 2023.
Outer rain bands from Hurricane Hone produced a prolonged period of heavy rainfall from Saturday, August 24 through most of Sunday, August 25. Several rain gages along the windward and southeast facing slopes of the Big Island reported 2-day totals greater than 20 inches. Fortunately, rain rates were mostly below an inch per hour, which mitigated more serious flooding beyond road closures in low-lying areas. The most significant road impacts included Highway 11 at Kawa Flats, and Cane Haul Road and Wood Valley Road near Pahala. North Kulani Road near Mountain View in the Puna District was also closed.
The following are notable automated rain gage totals for the 48-hour period ending at 6 AM HST, August 26. All amounts are in inches. These totals are considered preliminary for information purposes only.

Strong winds developed in advance of Hone during the day on Saturday, then continued into Sunday as Hone passed within 50 miles south of the Big Island. There were several reports of damage from trees and utility poles blown down on the Big Island, with additional reports of damage on Maui and Oahu. At one point, over 20,000 people were without power across the state, with most of the outages occurring on the Big Island
